Question about Toshiba 61H70 61" Rear Projection Television

1 Answer

Tohsiba 61HD70 Rear Projection

I have a Toshiba 61hd70 rear projection. The picture has begun to distort and there is basically a rainbow effect on the bottom and top of the screen. Scrolling words will start on the left then move to the center before going back down to the right side. It does not do this all the time, sometimes the picture is working good. Does this sound like a convergence problem? How do I fix it and is it something I can do myself?

Today the picture shrunk and a bunch of lines appeared in the middle. The picture then went off wouldnt turn back on and the red power light is flashing? After shutting it off for a few minutes the picture came back on, but will still flash on occasion.

Let me know if you need more informaiton.

Thanks

Yes, its a convergence problem and you may be able to fix this yourself if you have a soldering station and a few basic tools. Its possible that all that is necessary is to re-solder the pin connections on the convergence output ICs on the underside of the cicuit board. There may also be a poor solder connection on a jumper wire connection near the ICs. Its near the plastic frame. If this does not resolve the issue, you will need to replace the ICs. Remember to unplug the TV before doing any service.

Chances are you have a defective hyper module. The symptom with this problem is called piecrusting and appears as a squiggly and distorted picture, usually worse at the top. It may dissipate after 20 to 30 minutes as well. This module has been out of production for a few years but some regional companies will rebuild it for around $125.

Convergence color has a rainbow effect


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com
