Tv cutting on and off

Ebay lamps can cause this as they are not originals also the balast supply, is gas discharge type, can fail.

Main System Board is faulty.

** If you don't know what your doing back there, probably best not to go poking around. Power supply capacitors can bite hard and unmercifully, even when they've been unplugged for days. If you know how to safely discharge them, then do this before you touch anything. Until this is done, Keep one hand behind your back at all times, and this is no joke. To locate the power supply, follow the connections from the AC cord that go into the TV. The board that these wires are connected to is the power supply. Plenty of videos online about how to locate bad capacitors. Which is a very common problem in some tv's.

It sounds that the voltage output from its internal power regulator board is not proper. Check it.

Check your Stablelizer if it still goes off then check the timer 

Hi,

Please dont rate me if could not fix your problem. Check the tv lamp. If doest work well, replace it. Thank you..

try adjusting your color tuners located inside tv behind speakers.

You will most likely need both convergence IC's in your TV. Need a service call.

Normally this denotes a protect condition. Remove the speaker wires from the back of the amp and see if the green light stays on. If this fixes the problem, then there is a short circuit in your wires, speaker level volume control or speakers. The amp sees the short and goes into protect. After a couple seconds it closes the connection again and if the short is still present it goes back into protect.

Hi,
sounds like a picture tube problem its a problem that probably cant be fixed only by a professional
