SOURCE: TV keeps clicking on and off and doesn't come on.

When a TV is clicking on the back and it doesn't turn on its most likely the ballast, the clicking you hear is the ballast trying to turn the lamp on, but apparently it's doesn't have the enough power to send the amount of voltage that the lamp requires to turn on. So you might have to change the ballast board for your TV to work. Please contact me if you have any other question!! (:

My Techwood TV, The sound keeps going off, Turn tv off wait 30 secs turn on again, sound works for another 10 mins, Then repeat over & over


Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts. http://electronicshelponline.blogspot.com/

TV sound keeps going off and on,if I unplug it for a few days,it works fine for about a week. TV about 4 years old


Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
