Good Day;

You have poor connections on your "convergence IC's. Middle board IC's on large silver heat sink. Redo solder before total failure. Good Luck, big IRISH.

Wavy picture when first turned on and then shuts off within 30sec.unplug 2-3 times and then picture clears and stays on until turned off.Then repeats same problems when turned back on.


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

Toshiba projection tv with lines on screen


I have seen a lot of sets where the problem only happens when the set is first turned on---99% of the time one of the two STK-392-110 CONVERGENCE chips this set uses is Flakey--intermittant---The only way to know is replace both of the convergence IC's and see what you have---a bad IC can cause the set to shut down---and sooner or later the set will just shut down and not come on at all.

Let me know if you need more information about this type of repair as I have done hundreds of sets with this type of problem----every one I have ever seen where the convergence was intermittent----replacing the two IC's cured the problem.

Cannot reset vertical convergance


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

Toshiba 61H70 Weird Convergence Issue?


They may have gotten some cheap convergence ICs, thats a real possibility. I would recommend switching the two origional STK392-110 with some STK392-150 they will run alot cooler and last alot longer. Just use a good coating of heat sink compound on the back of the ICs. I will post a link where you can get top quality Convergence ICs and they provide free instalation instructions with pictures so you can do the job yourself in under an hour and save quite a bit of money. Heres the link.

42" RCA Projection TV - Sound good, but Picture goes out intermittently.


resolder the vertical output IC . bad solder there can make the CRTs blank for protection and you will lose the picture when the vertical drops out.

Mitsibishi 50" vs50607 convergence?


Rolling picture could be a pip module problem as both horizontal and vertical sync goes through the PIP module. These sets have been known to have bad caps in the pip board causeing loss of vertical sync.If you need any more info let me know.
