Mitsubishi WS-55819 55" Rear Projection Television - Page 3 - Answered Questions & Fixed issues

Is the model number of the tv correct? If not please get me the correct model number from the label at the back. As for this tv, no it is not HD.

Hi there you need to get an adapter for your component to HDMI
something like these:

Error Code Operational Check

Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occurred since the last Initialization

An error code of 22 indicates a shorted component or shorted power supply line.

Look for a button on the TV that says 'source'. Push it and wait for a few seconds, if the picture does not come back, push it again and wait a few more seconds. Do this until you have cycled through all of the input sources for your TV.

Hi Bross,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the dried electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.

For starters..Your convergence board is my first concern. If you can pull the board out, do so with great care. There are many, many bad grounds here by now. I can not say this enough. The convergence IC has been separated from the board. Examine the pins and resolder as necessary. Do not over solder, you do not want to solder the pins together or you will create a short. This goes for any IC with pins you resolder. Check the diode connections, resistor connections, jumper pin connections,connections where cables jump together between boards, capacitor grounds. If you can, check all electrolytic capacitors with an ESR meter, and replace capacitors as needed. Heat sinks will need resoldered tightly to the boards. Start with this and see what happens. There is much to do, with the one board. The next board will be the power supply, and you will have to repeat the effort just mentioned. But, try the first plan and see what happens.

Hi,
If you are handy with electronics stuff repair and can replace parts in circuit board (soldering work is required) then yes, you can repair it, I'll try best to assist you.
Let me know your expertise/ skills level to proceed. Problem seems in convergence output section of tv and two big black ICs will be replaced, soldering is needed to replace these ICs etc.
Thanks.

I had a similar problem. I had a 52" RCArear projection tv. It would do this when I initially turned on the television, but then after a few "on/off, on/off, on/off" cycles it would stay on. Eventually it started doing it more; until finally there was a spark and that was it. The tv was dead.The bloggers called it "the blinking green light of death" (because of green light on the panel).The power board is going out.ALSO holding down the Input and Menu buttons afterward will give you some diagnostic information via 2 sets of blinking indicator lights.

You may very well have issues with capacitors on this set being that it is or very similar to the V26 chassis. Since I have spare test lamps laying around, I would normally try that first. If the lamp still would not stay lit, I would then suspect the electrical chassis (capacitors). When I suspect the chassis, I can usually verify it by pulling it out and partially disassemble it and find blown capacitors

Some easy steps to determine where and what your problem is:


1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.


Let me know what more information you need--I am here to help.

Hi,
Most common problem in WS-55819 is failure of convergence output chips and blown pico fuses in power supply section.
You need to read out error code in tv, procedure is as follows:
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four
times.
Error codes detail:
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
"12" ... indicates no error has occurred.
"21" ... X-Ray Protect circuit.
"22" ... Short Protect circuit.
"23" ... Horizontal Deflection failure.
"24" ... Vertical Deflection failure.
This way you can determine what section got problem in tv and causing problem.
Let me know if you need further info.
Thanks.

It sounds like it is in high voltage shut down, you need to check and see if the horizontal transistor is not shorted, it is located by the fly back transformer, on a metal heat sink, and if it is OK then you probably have a bad convergence module. To have either one of the problems repair you are looking at around 450.

We have a 55in mitsubishi rear projection tv.
It was working great when the electricity went out (it was plug'd into a power strip) when the electricity came back on it did not turn on at all. The only thing that is showing that there is even any power going to it is a flashing green light by the reset button that does not turn off unless unplugged. I have followed the troubleshooting instructions for resetting etc but no help. Any suggestions would be appreciated. M Deisley

Hi,

Hello, friend you have a convergence issue, first see if they will move manually in your menu, they should be able to move up down left and right, and if not this is when two chips labeled STK392-xxx Failed. They can be located by finding the largest heat sinks in the unit.

Along with the possibility being an open resistor and or open fuse in the convergence circuit. All of the resistors around these chips should be checked pay attention to the ones that are standing up and they all should read low ohms, If they are in the k ohms they are probably open which is bad ,This is a tricky repair, if you have Never done this repair I don't suggest it friend.

But if you are willing to tackle this problem the only step by step procedure I found for you would be to watch someone do the repair, and this I found on the internet in the convergence problem screen. This will give you an idea of the work involved and also what the parts look like.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

First, to answer your last question, not all power outages and subsequent surges are created equally nor are all surge protectors. Also, after a power outage where the subsequent surge is so strong that it got past your surge protector and knocks out your TV and it's never done that before... REPLACE YOUR SURGE PROTECTOR.
However, that being said, in my experience it is unlikely that the TV is going to require a technician. Understand that the person that you spoke with in tech Support is not a technician and is reading off of a list of troubleshooting pages that are more extensive then what's in the manual. What the technician is probably not aware of is that your TV, like most home electronics, has a safety failsafe that requires the device to be separated from power completely before doing a system reset
First, after pressing the button it's supposed to flash for about a minute anyway but I'm assuming that after it's done pressing that the TV is still not firing up.
Unplug the TV, let it sit for an hour, plug it back in (to the wall, not the suspect surge protector). If the light is still flashing, press the reset button again and wait for it to stop flashing and attempt to turn it on again. If it doesn't work, unplug the TV, follow the same steps however, let it sit for 24 hours before plugging it back in. That length of time is not common but some sets do require it.
If none of this works, then I would say that it's time to call a technician.

you should be able to sharpen the picture yourself. most projections if you open them up you can adjust the canisters for color and sharpness. by turning them in a certain direction.

Ur tv is 100% have a convergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts on the tv convergence board,must be replaced to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

Well I see this frequently, lightning causes so many problems and does weird thing to electronics. What has most likely happened is that the Spike/Surge/Dropout, received, when the unit went Off & On again. has most likely destroyed the Input Buffer and Amplifier, in the front end.
Below is your service and repair manual, should you wish to DIY, below that is your User manual, both are invaluable when attempting any repairs.

This most likely, a simpler repair, I think, that if it is just what I have suggested, and it hasn't caused any "Other" damage, then I expect, it would cost around $175 - $250.00 parts & labor. BUT as usual please ask for a "Quote" BEFORE allowing any repair work to commence.
