Question about Mitsubishi WS-55859 55" Rear Projection Television

1 Answer

I have a Mitsubishi WS55859 and had the convergence IC go out recently.. I got a replacement STK393-110 from electronic repair kits and got it installed, however, now it's just making me mad. Upon powering the set up the convergence is way out, let it sit for about 10-15 minutes and convergence comes in. I've gone into the setup menu and adjusted things more times than I can count but can not seem to get this to stop. Does anyone have any ideas?

Most likely a solder issue if it works intermittent. I would double check the solder on the IC pins

Power comes on and the back off.... Code is two flashes then paus then two flashes.... Where do I check to find fuses to the convergence?


Hi,

This is a short protect error code. The affected parts is not only the pico fuses but also the convergence IC(STK393-110) that is mounted on the large aluminum heat sink. I have a link where you can buy the repair kit that includes steps-by-steps instructions that will guide you in the whole process of repair. Click the link below.

I have had a Mitsubishi DLP 52525 for 6+ years now and recently the green timer light started to rapidly blink when the unit was turned on and it continued to blink without the picture coming on. After...


I don't know about nettiser's credentials, but I've found plenty of people who would disagree with his/her assessment.

The flashing green timer light after a lightning storm seems to be a very common problem with old Mistubishi rear projection TV's. A friend and I had the exact same problem.

Using this and other sites, I spent $36 bucks and a little time with a soldering iron to replace the capacitors on the DM board and got mine up and running (WS55859). I've never really worked on electronic circuit boards before, but the helpful advice at these sites got me up and running. Definitely check it out before you hire someone or replace your TV:

HD 1080 Series (WD-55809) - Color convergence issue


I don't know of illustrated instructions but I can provide you with the service manual for your TV. It does have illustrations of disassembly and components as well as schematics. Your set very likely needs new convergence IC chips. This is a common problem with all projection TVs. The repair is not expensive ($60-75 in parts)  but does involve unsoldering and removing the old chips and soldering in new ones. Some times there are some fuses that need to be replaced as well. If you want the manual provide me with an email address.

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.

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...


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
