Turning on the tv, the green light comes on and I can hear it trying to turn on. Then, there is a clicking noise. Wait another clicking noise, then shuts off.

i have the same thing but what i do is unplug the tv and plug again till i hear a click then replug immediately and wait for the tv to come on .this is normally a symptom of a weak surge protector in the back, inside of the tv.it is normally not an expensive repair and better still if the tv is still on gaurantee it should cost nothing.

Replace the deflection board. You can get deflection boards from www.tvrepairworld.com for your model.

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
Thanks.

What light do you get, green blinking, red blinking, yellow steady light or yellow blinking light. The led lights will tell what is wrong with your tv.

un-plug the TV, wait at least 30 seconds, now turn it on again and close your ear to the back of the TV while turning it on, pay attention on hearing a hogh pitching sound coming from the back of the TV, the sound may be quick and go from a lower frequency to a higher frequency really quick if this sound is present then it means the switching power supply. if you don't hear any noises then the power supply is bad. It could also be a bad horizontal driver transistor, it depends on the model TV you got.

check power supply

it sounds like you could have a signal board problem they are pretty expensive but there is a web site that sells refurbed parts

hello sir

The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
