Mitsubishi WS-55819 55" Rear Projection Television - Page 7 Questions & Answers
I have a mitsubishi WS55819 and every time i turn
I suspect what you are describing is a convergence problem---when it acts up go into the customer menu and select convergence--then advanced--it will bring up a grid of lines---if red, or blue is skewed this is your problem.
I have repaired hundreds of these sets--this model uses two of the STK-392-570 convergence chips and I have seen many where the convergence comes and goes--what happens in these sets is not a soldering problem but the pins inside the chips come loose--Each chip has about 16 pins--I have had ones that when I removed the solder pins fell out of the chip.
The pair of chips can be bought on Ebay for about 12 dollars plus shipping (I know the best seller there) and if you or someone you know can do it you can save the set and a lot of money.
Most shops are going to charge at LEAST 300 for this repair--and some will not do it in your home--it can be easily done in the home and takes about 1 hour.
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS MODEL.
If you think you can do it yourself let me know and we will get the instructions to you.

My mitsubishi ws-55919 powers on then powers off
Did you do the self check this set should have? When you turn it on and it goes off-----On the front of the set press and hold both the MENU and INPUT OR DEVICE BUTTONS FOR AT LEAST 5 SECONDS AND THEN RELEASE BOTH BUTTONS.
The power light should blink a two digit error code--for example--two blinks, a pause, and two blinks---this is the most common error code and I can tell you exactly what is needed to fix it. I have fixed hundreds of these sets with the 2-2 error code=====98% of the time it is the same problem.
If you let me know what error code you find---I will tell you what it means and what you have to do----I hope you have the 2-2 error code.
Let me know what error code you find--it will repeat the code at least 5 times.

Need assistance changing the convergence IC's
I have step by step start to finish instructions for this repair if you want them.
You can use regular solder--the original is lead free, it does not matter.
If you want the instructions rate this solution with 4 thumbs and I will post the instructions for you.
they will tell you everything you need to do the repair and step by step start to finish instructions.

My picture goes 3-d like on the sides, and if your
WS-55819 uses two of the STK-392-570 convergence chips-----usually it is not a soldering problem--I have seen dozens of these sets that use this chip--some of the chips before they totally fail do this--convergence comes and goes--I have also seen several when I unsoldered them that the pins literally fell out of the chips--
I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--if you can solder well and are handy--you can buy a pair of the chips on Ebay for less than 13 dollars plus shipping.
I cannot give you my email address but..........
I have also photos of a few things you need to look at if you do this repair----The instructions tell you how to do the repair and also tell you EVERYTHING you will need to do it.
If you have some idea of how I can get the instructions to you other than here let me know--
Take my word for it---if convergence is jumping in or out you need to replace both chips and the set will not have this problem again for 5-8 years--lifespan on these parts.

Can not align red even though convergence board WS-55819
Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?
98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.
WHICH DID YOU REPLACE?
I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Convergence is out at the corners, and adjust
you have a convergence amp ic that has failed
you will need to repalce them and perahps a resistor or two and possibly a pico fuse
if you have the tools and soldering station and some know how you can change them your self or
you may want to recruit a local tech to assist you with this repair
Picture goes in and out
Most likely cold solder joint around the p.i.p module;
remove the back cover and try moving lightly some of the circuits that are standing up(while the set is working)just be careful where you put your fingers,if that makes a difference you`ll need to remove those boards (plugins)and solder the terminals.Also the main board will have to be lifted and and soldered where the boards connect. good luck

Can't get it back to tv input - tv connected to 2
You set may be set to Home Theater mode.
I think it is in the advanced menu.
Set home theater to off. This will fix the input on the television to input one, no matter what you do.
I hope that this helps you.

Mitsubishi 55" rear projection TV, wouldn't turn off
um . that model doesn't have a reset button . but if no lights on front of the set even blink when you press the power button on the front or on the remote .then suspect front panel buttons ,with that model.
Picture is double and colors are out of focus
This is a common problem that would require 2 Convergence output IC's to fix . The part # STK392-560 replace with STK 392-570. a repair shop would charge between $200-$300 (parts cost $60.00)
Screen seems to have convex curves at the top and
If it is convergence and was soldered once--it will most likely need the convergence chips replaced--this model uses two STK-392-570 chips----even if bad soldering was the first problem based on the fact that the set is a 2001 model--should have just replaced the chips then as the amount of work to get at them to solder is the same as changing them--if the chips are replaced the set should be good for 5-8 years--not 3 years.
Let me know if you have questions or need advice.

We have a ws55819, and it won't power on at all
it will probably be the power supply
so first you will need to check for obvious stuff like board fuse,switch,blown caps or dry joints
if looks ok then check the dc voltage on mains filter cap (only do this if you are experienced in electronics) if ok you will have to determine how the stage is not been driven google up the number on the drive chip and check if voltages are how the should be.
Mitsubishi ws55819 wont power on?
The would be due to a bad power supply a switch out would find you a working Tv again now the power unit can be reapaired but you might just want to save face here and get a new one the folks at
www.partstore.com have been benefical to me in finding the parts for all my clients I am sure they will help you with your tv parts if you like to do a "do it yourself repair". Please do a review/rating on my solution here I do take time out of my busy day answering free questions it does not hurt me to do it but I look for good ratings, Thanks Btw, I’m available to help over the phone in case u need at
