You probably have convergence IC's bad (part number STK392-040). This is not uncommon in these sets. The picture is probably a little cloudy and faded on the edges. This is an indication that the fluid in the blue crt may need changing also.

Sound and no picture


Set was actually made by Samsung who owns and uses that name.

Rear projection with three picture tubes.

Problem could be in the high voltage area and likely is.

Only other area that could cause this is the main board.

In either case someone needs to open set and do some checks.

Model # pt4298 i have no picture and sound


Disconnect all scart cables and see what happens if you change sources on the remote. If no response and still no pix or audio then it is likely that you have a power supply fault.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.
