No there is no reset button . you would unplug the set for 5 min's and this will allow a reset . . with the symptoms you give id say you have a shut down issue . the set has detected a error and is putting it into a shut down sequence to protect it self from major damage .

A chirping sound from a TV set is the switch mode power supply trying to start up, but gets shut down because of a major short inside the set or in one of the circuits.. Most likly in this set, the horizontal output transistor is shorted because of a defective flyback transformer. Thats whats the common problem is with this set. A repair like this, if this is the only parts that are bad, will run you about 300 to 400 bucks or so. In some cases, not many but a few times, I have seen poor solder connections on L401 cause the horizontal output transistor to go bad. There are no user replacable parts inside this set, so please play it safe and seek out a pro to assist you in this repair. Good luck PS Please do not forget to rate this thread.

Most likely there was one or more marginal connections on the main board and moving the set has completely opened those connections. If you can solder, try resoldering any connections on the boards that appear to be grainy or have rings. Update this with the results. That may resolve the problem. If not, we'll look further into the set for component failures.

Failure of the HV splitter was a very common problem when I was doing these big screens on the road. The set won't come on if the splitter shorts. We used to test if that was the cause by pulling the HV input lead out of the splitter (leaving it still inside the plastic cup so it wouldn't arc anywhere) and turning the set on. Most often the set would fire right up (without picture of course).
I believe the RCA part number for the splitter is 205064, and it's available from a number of sources. I'm not home right now so I can't check. If I have the number wrong I'll post a follow-up comment.
