    OK, every once and a while the picture come on. Is there a quick fix or is this TV dead.

This is due to the fact that the front end of the RF section is faulty and so there is no signal available to the video amp to be processed.
The fault can be any where from the input tuner, the VI F/SIF sections or the conversions( A/D).
You might ahve to start with a signal test to arrive easily at issue, possible that it can be the tuner itself as it most prone to failure.
Finally check the mode section secction of the AV/tuner which can be a suspected area due to a gate failure.

    Could be loose cconnecction or dry soldering on the PCB , you can tap on board to confirm , do a good soldering touch up.

DVD Player doesn't work on DRC6355N VCR/DVD Combo


With most dvd/vcr combo units there is separate wiring. When I use my emerson combo unit I have it wired that I have to be on different inputs on my tv to view a dvd and a vhs. On some units the vcr portion is wired via a regular cable line, while the dvd portion is wired with the yellow, red, and white component cable. Try inserting a dvd and scrolling through your tv inputs until you find the picture or check your wiring to ensure nothing has come loose. If that has no result you could try wiring it differently if possible to eliminate that as a possibility.

Whole Screen Turns Blue in seconds....


This could be a problem with the Blue CRT it archs or overdrives intermittently. I would have a technician test the set and give you an estimate - if it's the CRT it's usually not worth repair- but it could be video or a screen voltage related problem. It's worth the estimate.

Can you try just running a/v cable from your tv output to the inputs on the ilo, then whatever you watch on your tv you can record on your dvd burner. My new SDTV doesnt have audio out except Coax so this won't work for me on that tv. Why doesnt the newer tv's have audio AND video outputs???
