take the back off and get to the power supply most likely you will find some bad capacitors in it they will probaly have the tops of the caps bulgeing.
SOURCE: Soyo 32'' power supply is good checked it in another tv
Check caps and look for fuses there should be two.. Check continuity on transformers and if you find one that is open that's it. You can sometimes replace the transformer with one from another board. don't have to be same brand..
SOURCE: Olevia 42" LT42HVi has sound but picture had gone blank.
You do have sound, but no picture.
I believe the power supply and main board is ok, because you can hear the audio.
Most of the majority of these problems that have no picture is the back light inverter. That's what supplies power to the screen. I would look into that as the source of the problem.
SOURCE: fuse and power supply look ok to the eye slight
Your power supply on the dc output should have the floowing DC voltages, 5v, 12v, and 24v. Just start probing the connectors of the power supply. 24v is needed for the backlights inverter board, 12v for sounds, 5v for logic board.
SOURCE: no picture power supply appears to be fine removed
Yes,this could be ur problems.But u have sound right?Not u might have more problems,that a start.
