Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

TV pops and shuts off

My 55 inch Toshiba has multiple issues. The picture will "Bend" top to bottom distorting the image on the screen. We can fix it by turning off/turning back on the TV and sometimes it fixes it and some times 15 minutes later it will reoccur. The TV also pops frequnetly and then shuts its self off for a second and then turns itself back on - like a power surge. Again sometimes it does it multiple times while watch a show and some times not at all. The TV is part of a surround sound system and none of the other components experience any problems working with out the TV (DVD/CD Player, Receiver.

Its two maybe three issues that your having trouble with. First thing is the convergence. That problem could be a cold solder connection on the convergence IC's or the Ic's have a thermal problem, as after they heat up they go bad. The second is the popping. This could be an issue with the rear channel Audio output Ic intermittanly shorting and shutting down the set, or it could be a bad ground around the picture tubes, or a leaky hi voltage block, or a second anode lead going to the picture tubes could be split. The other common problem with this set is the STR#### regulator IC in the power supply. Now unless your a tech you shouldnt attempt any of these repairs as there is very high voltage in this set and could cause great harm to you. seek the help of an authorized repair shop for Toshiba. Try this # if you cant find one in your area 800-457-7777 Good Luck

How to widen my curtis 42 inch flat sreen top and bottom


Some TV's have a zoom function others do not. The program you're watching controls whether the top and bottom of the screen have black bars and is not the fault of the TV. Widening the picture cuts off a lot of the viewable picture and distorts the image. Circles tend to be oval. If your TV has a zoom function, use it.

My 46 inch samsung has a picture distortion, it's like it has a mirror image , how can i fix this?


Anthony, you did not list a model #. If you would it makes it eassier to determine what may have happened with your Samsung TV. An LCD would start with LN46----.
I have had screen issues with some samsung product. As well as other makes of televisions that use Samsung 46 inch dislay lcd.
