Mitsubishi WS-55819 55" Rear Projection Television - Page 6 Questions & Answers
Scored a Mitsubishi rear projection
Hi
Thanks for using FixYa. From what you have described it seems that you have to
replace the convergence IC and check power resistor for leakage, if values are
not exact you have to replace them. The typical cost to get this fixed by a pro
is about $300 - and it doesn't mean that he/they will do a job better than you
do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do
it yourself. Replacing only the IC's MAY solve the problem; however, many
people have also had blown resistors requiring replacement. Why would you ask
should you replace both of the IC's if only one is shot?! If one is shot the
other one is not far away and for that little price of the chips it worth
changing them both at the same time. Also the convergence board should be
checked for cracked solder. If you replace the ICs and the resistors are shot,
the ICs may blow again almost immediately, meaning you may have to do the
repair twice. Its great however, if you are replacing the complete board. Please do accept the solution if the issue is resolved or else
revert for further assistance.
Thanks

WS-55819 TV, about 8 years old, stopped working.
DO THE SELF CHECK YOUR SET HAS:
When you turn it on and power light goes off in a few seconds;
On the front of the set push and hold both the Menu and Input (Device) buttons for at least 5 seconds and release both.
Power light will then blink a two digit code, most common is 2 blinks, a pause and 2 blinks--it will repeat the code at least 5 times.
Let me know what code you find and I will tell you what it means and maybe what is wrong with your tv.
I hope you find 2,2, as that is the most easy to fix.

Mitsubishi WS - 55819 Power
Hi,
Check / replace fuse F9A04 in power supply that provide +24V to convergence out chips in TV.
If fuse blew off again then convergence out chips would be replaced.
Let me know if you have additional question.
Thanks.
Turns off immediatley
WS-55819?
If the power light comes on for a moment and then goes off---Please do the self check this set has.
When it shuts off and the power light goes off:
ON THE FRONT OF THE SET press both the Menu and Input (or device) buttons at the same time and hold both of them for at least 5 seconds and then release both.
The power light should blink a two digit error code---the most common one is 2 blinks, a pause and 2 blinks ------it will repeat the code at least 5 times----- after that to get it to repeat you would have to unplug the set and try to turn it on again and repeat the process.
Let me know what error code you find---I hope it is 2,2 error code---for many people that can be a do it yourself repair.

Inputs randomly stop registering, screen goes blank
Code 12 indicates no error. Push the Menu and Device buttons after the TV has shut off to get the proper code, not after you unplug and plug it back.
It seems your set is not Mitsubishi WS-55819 so it will help if you can give the exact model.

I got a free WS-55819 tv because overtime the red
I am the right person for you to talk to. I know these sets very well--ws-55819 uses two of the STK-392-570 convergence chips.
What I have seen happen in dozens of these is one of the chips develops internal connection problems--resoldering the pins on the bottom of the board will not fix this.
If the set is working you can get a pair of the chips and almost everything else to do this repair for about 30 dollars total.
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR ON THIS MODEL.
I have fixed hundreds of these sets with this kind of problem.
The instructions tell you everything you will need and how to do the repair from start to finish.
This is a HD set and cost a lot of money when new--if you want the instructions and where to get the parts let me know. I am here to help--by the way--do not burn pressed wood--it contains nasty chemicals like formaldehyde.

Is there a way to hookup more than 1 hd device at
if your asking if you can hook-up more than one HDMI device into a tv with only one HDMI input, then the answer is yes. The cheapest way is to buy an HDMI switcher. Some are remotely controlled some are manual, all depends on what you want to spend. The other more high-end solution is to buy a good home theater receiver with multiple HDMI inputs. A quick google search should find you any of these products.
When I try to use the advanced convergence, the
WS-55819 uses two of the STK-392-570 CONVERGENCE Ic chips. If convergence is skewed and or will not adjust in some area both chips and any of the 3.9 ohm blue protect resistors right in front of them need to be replaced.
You can buy a pair of the chips on Ebay for under 14 dollars plus shipping---total parts cost for this fix should be under 30 dollars---most shops are going to get 300 or more for this repair in this set.
I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL. If you or someone you know can do it you can save the set and a lot of money. The instructions tell you every thing you will need for the repair.
If you want them let me know and I will post them here for you. If you have questions or need help let me know.

Timer light keeps blinking and can not stop it or
THIS IS MY STANDARD ANSWER TO THIS QUESTION==SOMETIMES PEOPLE DO NOT
TRY THE EASY POSSIBLE REASON--IF YOU HAVE ANY QUESTIONS LET ME
KNOW---IF THE ANSWER TOLD YOU something you did not know--rate the
solution----
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.

Our tv just turns itself after 10 minutes we can
Replace the function switches. To see if switches are bad remove front grill and small panel if needed. disconnect the plug that goes to the switch board. You can use the remote to operate the tv. If the problem stops the switches are bad. Common problem on this set. Also swollen capacitors in the Digital module will cause shut down.
