Most times when this unit chirps the horiz output transistor has shorted. If I remember correctly the transistor is Q401. Some times the flyback transformer can be bad as well T401.

RCA BIG SCREEN TV WONT TURN ON HELP !!!!!!!!!!!!


Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

Best Regards,

James

Picture to big, half the screen is cut off


First off did you get the right remote. I had this same problem and was not able to fix it because I had the wrong remote. You should have DSP mode on the remote near the select / ok button in the middle of the remote. The left and right arrows allow you to move through the different picture zoom / format settings. You will need to set yours to the 16/9 format to get it correct. I use the
RCA Universal Remote 5717P. Works great.

Thanks.
