Question about Sony KV-36XBR400 36" TV

1 Answer

TV shuts off by itself in full picture mode

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.

42 inch Samsung DLP TV shuts off by itself. I can turn it back on and sometimes it stays on and other times shuts off within seconds. Some days it stays on all day without a problem. Other days it shuts...

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.

Tv turns on and off by itself

Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.

TV turns itself off after a few seconds, no picture at all

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/

TV Switches itself back to standby mode continuously

if your remote is ok then this is due to power supply failure in your tv. either it is loose in oscillator ckt in switching section or it has failed. if not tech person call tech to fix it. not a major problem.
