Tip

Projection TV Convergence


Your Projection TV has what appears to be ghosts in red, green and blue on it.
If the error is severe, this is a convergence problem. Convergence ICs are not too hard to change but require good soldering skills. There can be two or three ICs. There may be a blown solder-in fuse or two.
A service shop will charge $200 -$600 depending on service call, parts costs, labour, etc.
A slight error in one or two colours that just barely won't correct is an alignment issue. There are a lot of internal adjustments done by remote control. Digital adjustments are not forgiving. Have a pro do the adjustment.

Can't correct my red blue convergence manually or by using factory preset...the unit is 7 years old, is my picture tube bad?


You have bad convergence ICs. There are 2 ICs in the convergence circuit, one is for the Blue the other is for the Red. You can buy 2 ICs for under $40.00. Replacing these ICs require soldering and desoldering skills. Sometime, the resistors in the convergence circuit go bad also. Be very careful, there is a very high voltage in a CRT projection TV the voltage is over 30,000 volts.
Best of Luck

Mitsubishi 1080 hd ws-65809 wont power up


This issue is almost always caused by a faulty Convergence IC inside your TV. These chips heat up and can become damaged over time. The most common cause I have seen for the picture distortion is the heat of the Convergence IC weakening the solder connection to the TV circuit board. If you look on various messages board you will see people rigging wooden dowels and other items to apply pressure to the chips in order to correct their picture issue. This works because when the solder joint is weakened the chip becomes loose and vibrations or pressure will cause it to work or not work correctly. Aside from all that information the correct fix is to have the IC chips replaces on your TV.

The solutions for this issue are as follows:

1. located a tv repair shop that will replace the parts for you. I had the same issue with my 65" Tv and the quote was $350 for the labor and parts.


2. You can ordered the IC replacements yourself online by going to google and looking up a reseller of the STK392-110 Convergence IC that is inside your model TV. You will need 2 of them and they cost around $6 each. If you have the soldering skills to remove the old chips and install the new ones this is by far the most cost effective route. It is a fairly simple process and guides can be found online.

Toshiba big screen The tv is like double exposed . I have a toshiba big screen tv and I have double images in red and green. How do I fix this problem?


This is likely your convergence ICs(chips). If you can bump it then the ICs (chips) are still ok, it just needs resoldering.
my company charges $300-400 for the full repair (replacing ICs, full realignment plus cleaning)
if you can find a company that will resolder for you, it could cost $100-200 maybe. if you are a handy person with soldering skills, you could repair yourself. i can instruct if needed, but convergence IC soldering requires decent soldering skills. you will find the ICs on the largest heatsink in the tv. the part number starts with STK. if you replace them, check the resistors in front of them and replace accordingly. most toshiba will blow up to 3 fuses (f850, f851, f852)

Sounds like possible solder connections on the convergence ICs. If so, you will see the red, green, and blue not lining up on ever input and even the mits menu. If you can bump it to correct, its just a solder connection, but if its out all the time then the ICs need replaced. This is a difficult repair only recommended for skilled technicians (40 solder connections + possible re-alignment needed)
