SOURCE: screen went black on my 42" sanyo model dp42647 lcd

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

That is odd.

What I'd do is open up the TV and try moving the LDVS cable (the one with many many wires on the main board - no other has as many as it does) to see if that's going to affect the image.

Chances are it would - connectors wear out, get rusty etc. and this is a relatively common issue.

It may also be a bad connection on the other side of the T-CON board (which is where that cable leads to), but that is less likely.

It may also be a bad T-CON board itself.

Alas, no silver bullet for that issue.

I have a Sanyo TV model HT30744. The problem is that there is sound but no picture when the TV is turned on. After about 10-15 minutes a picture will appear. Distorted at first, the picture gradually...


Yes, its still reasonable to have it fix , because the tv will be working fine after they replace probably the tube.

Hope that helps.........
