It looks like its time to call Sony. You might do a search over on AVS for your make and model to see what issues have shown up.

for instance, I know for my Sony A2020 there was a problem with the early chips and purple blotching on screen.

If you already know what the issue is and know of others that have had a similar issue, it might make dealing with Sony more expedient.
