hi
this tv has only the red led is light but it is oscillating very fast, and is not powering up, i tested the 5v but i found it goes from 4.6v to 5.2v up and down ,even every voltage on the board is oscillating even the main capacitors, their volt is not stable.. i tested all the capacitors with no sucess

Check all the diodes and check the bottom of the power board for bad/cold solder joints, look closely sometimes they look good but are bad or loose.
