Question about Toshiba 55HX70 55" Rear Projection Television

1 Answer

Won't lock on standard resolution

Replaced the STK392's. Problem solved. Then I was in the service menu doing convergence in 1080i mode. When I went to exit (press 7 . . .) I think I hit a wrong key. The TV switched to the off-air input while still in service mode. I hit a couple remote keys (bad idea). I ended up with great looking 1080i but the standard def resolutions look very bad. Colors are dramatically mis-converged. The set will shut down after a few seconds of this. The power led flashes. (I had my own shop for a couple decades but I am not transitioning to PDF manuals very well.) I would be very grateful for some clues or maybe a magic bullet. Thanks.

Re: Won't lock on standard resolution

LOL No such thing my friend. Thats what happens when you mess with the wrong buttons I'm afraid in the service maode. You will need to go back to the service menu and start over from scratch in the other scan modes. Sorry, no magic bullet

Display to big with PS3

All CRT RPTVs have overscan, and some sources bring this out more than others.

It can always be cured to at least be able to see the needed parts of the pic, but hoses your picture beyond belief, and correcting that takes time, experience, patience and expertise.

I do overscan reduction on all CRT RPTVs as part of what my calibrations offer, but charge extra to do so.

Samsung HC-P4752W Blurry ONLY on HD Channels

Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
