Question about Mitsubishi WS-55859 55" Rear Projection Television

1 Answer

Mitsubishi WS55859, was getting 2 and 2 blink, replaced the pico fuses and convergence chip - 3 times, each fix worked better than the next but evenually failed - now have it working, trying to adjust convergence and red and blue crosshair lines will move up and down, but will not move far enough right (red) or left (blue) to align with the green crosshairs. In the fine tuning of convergence, the top middle is close, then get distorted at bottom and left and right - try IC convergence chip AGAIN, or am I missing something?

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

My Mitsubishi tv vs70707 convergence problems. I just replaced my 2 STK convergence chips, and double check my soldering. Still have 3d pictures and can't find pico fuses. Glass fuses are ok.


Need a better picture, but usually fuses are listed as F(number) and would be on the power input to the STK chips. The resistors should be checked as well.

What pico fuses does the Mitsubishi ws55859 use? My email is duh024@icloud.com


There should be 3 fuses...the picture is attached. The two that fail most often are the F9A04 and F9A05. Depending on the problem, you may need to replace 2 Convergence IC's (STK392-570).

My mitsubishi 48' wideacreen tv will not turn on.


Sure, two,two is short protection: One of the two pico fuses that protects the convergence circuit is blown----you will need to replace both chips (Need a exact model number to tell which) and the pico fuse that is blown.

Mitsubishi 65" WS-65869 Blinking Green Light 3-2 pattern,


two ideas:

Make sure you tested the pico fuses inside the unit with the caps==two or three of them.


Also from front of set behind speaker grill unplug both plugs that go up to front keyboard--set will still work with remote===if set functions now then the reset micro switch is bad/damaged.

Will bad convergance ic's keep my Mitsubishi


If one of the two stk-392-570 chips has shorted it will blow a pico fuse on middle board and set will not come on.

Plug set in, turn on, when green power light goes out on the front of the set press and hold both the menu and input (device) buttons for at least five seconds and release both.

Power light will blink a two digit error code: if 2,2 it is a blown pico fuse and the chips also must be replaced. I have start to finish step by step instructions that are available if the customer selects me to answer in the new Marketplace here on Fixya.

see attached photo of chip and also part of middle board with the green pico fuses.

hi,
Error code 2-2 indicates "Short Protect Circuit" problem in tv.
Need to check pico fuses in power supply as one or two got blown due to bad convergence chips.
Below is an exploded view of tv chassis, power supply and convergence area has been marked to give you better idea to look for pico fuses.
Unplug tv from wall socket before to repair/check any thing inside tv.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Mitsubishi WS55859 turns on for 3 sec. then turns off


Ic's went out again. Did you check all the bias resistors? Must always look the board over for cold solder joints also.

Mitsubish WS-819 Protective Shutdown. 2 blinks, pause, 2 blinks


Over 95% of the time a 2 - 2 blink code on that model is a convergence output problem. You need to replace both of the convergence output IC's and perhaps the pico fuses feeding them voltage. The pico fuses are F9A04 and F9A05. They are on the same board with the convergence outputs.
