WHEN FIRST STARTED PICRURE LOOKS LIKE A BAD ANTENNA SIGNAL.AFTER STARTING A SECONDE TIME IT CLEARS RIGHT UP. SONY MODEL # KD-30XS955

Anthony from Infotech posted the solution at another location:
6 and 7 blink codes 90% of the time are failure of the two control chips on the DZ board IC8002 and IC6501 both are MCZ3001D available from www.mcmelectronics.com
An ability to solder well is required to do this
Alternate solutions are to send the board to www.ptscorp.com and they will replace the chips or replace the board subject to availibility
A technician would charge $350 for this depends where you are

Short circuit protection circuit energizes, and shuts the TV down to prevent further damages. Check for any short circuit at its main board components; especially to horizontal output transistor. Contact any service technician. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view. It will make surf easy.

The flashing light is "Code" for diagnostics. Count the flashes before it pauses. Some Sony user manuals will have the answer in the troubleshooting section of the manual. If you don't have your manual,

Sounds like you have an antenna problem. Find where the antenna plugs into the radio. Unplug it and find a nail or something the same diameter as the center pin wrap about 3-5 turns of a four foot piece of wire around the nail and plug the nail into the antenna input on the radio. If it clears up reception you have a bad or grounded antenna. Follow the antenna wire back to the windshield or fender etc. mounted antenna, sometimes there are other plug in points that get knocked loose.

Since the PIP is working properly, I would think that the set is hooked up properly. Make sure that the main picture (the one on the left), is on the proper Antenna input, I.e. antenna A. If the hook up is correct and all inputs are correct, then, the problem is probably the main tuner.
