We switched apartments and now all of a sudden this TV is having issues. It does not stay on for very long at all--yet when I have it on doublt picture mode, it often remains powered on. Occasionally it will turn off constantly, regardless of being in double picture mode, and there is no hope of keeping it on. I have noticed that while watching wide-screen movies on it, there is a better chance it stays on also. I have a hunch it must be an easy fix, but I don't know anything about TV repairs.

Re: TV shuts off by itself in full picture mode
The Sony sets are full of circuits which monitor and detect faults throughout the set. These circuits monitor main B+ voltage and current, low B+ voltage and current, vertical and horizontal circuits and CRT current. Finding an intermitten problem in these circuits is no easy task and should be left to someone with experience in Sony sets.

I don't think you had backlight issues like you thought you did as the set should have shut down the backlights totally as soon as it sensed over voltage or over current, I'd try a new main board and see if that fixes things up for you
I bypassed the safety switch (it was bad) and vacuumed and blew out all of the dust. So far with this set, 3 years old, I have replaced the bulb twice,it exploded both times, and the color wheel which also exploded! We love the picture but the next time it goes out, it goes out to the trash and I will purchase a top of the line LED/LCD set. No moving parts!!! Samsung designed and manufactured a whole bunch of lemon sets and will not admit it. I have found several hundred complaints about their DLP sets and only a few on other brands.
It sounds like an eeprom issue. But you can try to reset the set. Turn the set off by the main power on the set. wait a minute or two then together push both the main power button and the standby power button. This should resett the tv. If that doesnt work you will need service as the zoom and the various modes are all controled by the eeprom. Only hold the two buttons for a second. sometimes you will hear the crts discharge while resetting.Hope this helps
