Check its horizontal output section and CRT base board components. Replace damaged ones.

There is some shorted component/s on the main power supply regulator baord to your TV. Work with main power board circuit is fatal to any inexperienced person, as 80% of the components at this stage will be Hot [electrically], when the set is switched ON. Without switch it ON, you cant check the voltages at this section. S, if you are not experienced to do this work, contact any experienced service technician to get this set repaired.

Maybe theres a loose connection in the cercuit board, you need to resolder the board. you need a qualified technician to fix your problem.

it sounds like a memory chip going bad, or you are having tuner problems

Ur IR control board one of it button might be damage.Tries unplug the tv for couple hours see if it reset itself tv might work again.If u lucky.Or the IR control board is bad or the IC that help the IR board is dead.

If you can hear sound and the sound coems from your TV, try changing the volume with teh TV remote control. Your TV isn't off it is still on. Just the video board or portion is cutting out. this could be a ton of things, I would try changing out the power strip or plugging the tv into the wall directly to make sure it has enough power. other then that you can try a home brew solution like putting a fan next to your tv to cool the component that seems to be overheating and shutting down your picture.

Ur power inverter board is dead.
U need new one.

the power supply is main cause problem of tv,you coldsolder the main board of your tv.

if you see near plug it might be due to sparking in socket or plug by calling electrician it might be repaired easily. But you have seen blue light in tv & chattering sound than it is dangerous. do not put on tv &call skilled person.
