1 Answer

Toshiba 42H81 I don't how this happened but the question writen under my name iduno14, was not the question i asked but one for a 32a33 ever what that is. My problem is my Toshiba 42H81 Clicks when pluged in, but i get no picture or sound ever. The Red power light blicks continuously and you cannot turn it off without unplugging the set. I know i will probalbly have to call a technician but thought it my be cheaper if i found the parts.

    Mine just started doing the same thing. It clicks on and off but never stays on long enought to get a picture or sound.

    My Toshiba would click off and the light would blink and the only way to get it to turn back on was to unplug and plug in again. Yesterday there was a static sound and it went off. When I plugged it back in we only had sound and no picture. I am being told over the phone by a tech. the parts are too expensive & potentially unavailable. Convergence and lights...any truth to this. He hasn't even checked anything.

Won't be any cheaper if you go looking and you'll probably get sold some chinese knock-offs anyway... It sounds like you'll need to replace the convergence amps, both STK392-110 Sanyo originals. Also the tech will test the yoke return path circuits and the resistors therein... Likely s/he'll find that one or more has change slightly in value and change those as well for a more reliable repair...
Hope this helps!

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
