Question about Mitsubishi WS-55809 55" Rear Projection Television

Mitsubishi WS-55809 dark scenes display green lines in background

I just add my convergence power supplies replaced at a TV repair shop, now during dark scenes I can notice wavy horizontal green lines in the background, they are in no defined pattern, but some of them almost look like the picture looked before my convergence ICs were repaired (an arc at the top and bottom of the display)

You have either bad convergence ICs or just bad grounds on the IC. I would go ahead and replace the ICs and check those small ohm resistors, as you have to pull the signal board out anyway. For futher instructions see the website www.TvRepairKits.com. They may have what you are looking for. Be sure you have the TV model number next to you. Thanks for asking and show a few hands of support!

Flashing green light when i hit power botton.


2 blinks and 2 blinks is the error code for short protection---usually in this set the most common cause is a bad convergence chip that has shorted; it takes out one or two pico fuses in the set's power supply---the set detects no voltage to the convergence chips and shuts down.

Almost any good tech can do this repair in your home in about a hour or less--shops charge 300-400 for this kind of repair--look in your area and find someone who has done this brand before--I do lots of them here for 200-250 depending on model---This is the slow time of year for TV repair shops so look around--if someone says it "has to go to the shop" keep looking.


I have detailed start to finish instructions (verify the model number to me) for doing this repair; If you have the skill to do it yourself--you can buy the chip on Ebay A WS-55809 model uses a single STK-393-110 chip---about 14 dollars on Ebay plus shipping----let me know if you want the instructions and if you have questions reply to this post here.

Ws 55809 convergence


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
