My Sony KV-24FV-12 was bought a little over 3 year ago and the extended warranty has expired. It's been a decent TV, although I don't know whether I'll buy another Sony as the last few I've owned have developed problems early on.
This KV-24FV-12 has a few problems. it's connected to a Direct TV Satellite dish and a Panasonic VCR. It's been used rather extensively, but onky for viewing TV or watching DVDs.
The most annoying problem it developed a couple weeks ago is an intermittant blackout on any channel, even when watching a DVD, The picture will be fine then all of a sudden the screen will go black for a second, then the picture will return to normal and a couple seconds later it will go black again. this sequence will repeat itself, then it will cease for several minutes before acting up again.
Seems like the audio does not drop off when the picture goes blank. It happens on all channels from Direct TV as well as when I have the Direct TV box turned off and am watching a DVD. It seesm to be occuring more frequently, and I cannot watch the TV anymore it's such so annoying.
On the same TV, I've noticed the picture quality has started to deteriorate. It's not as rich as other TVs in the house, the colours almost look faded. Sometimes when I look at the Direct TV guide the background colours are faded, other times I'll switch to the guide and they're nice and strong, and this is without switching the picture mode to Vivid, Sports, etc.
Lastly, I get a high pitch audio hum when the volume is turned down low, it goes away when I turn up the Volume, but I don't like to have the Volume at a very loud level at times.
Thanks for any help,

Re: Sony KV-24FV12 Image intermittant Blackout
the picture tube on your TV set is exausted. Please contact your nearest Authorized Sony Service for further help/advice.
After all, Sony is a good choice. The next TV set you buy could be one of Sony-s Bravia LCD.

Hello!I bought 12 years ago a SONY TV KV-28FX60D with out any technical issue so far.The last couple of days I powered on and after five minutes it starts showing only half of the screen, losing the bottom half of the picture. what do you think it might be. Can you suggest a part to be replaced and if it is worth fixing, cost wise? Thanks KONSTANTINOS

know this isn't what you want to hear, but the problem you've described
can't be fixed with troubleshooting. Your TV will have to be repaired.
There is a part that has developed a defect and needs to be replaced. If you bought the TV within the last year, it should still be under the manufacturer's warranty. The repair would also be covered under an extended warranty if you purchased one.
If you're out of warranty, before paying a TV
repair person $75+ to diagnose the problem, ask yourself if you're
willing to pay $150 minimum to fix this particular set. Also keep in
mind that TVs that are 3 years old or more have a very limited number of replacement
parts still available. Normally it will cost at least $75 to have the
set looked at by a repair shop (diagnostics). If the part needed to
complete the repair isn't available, you won't get that money back.
I hope I've provided you useful assistance and that this information
allows you to make an informed decision as to how to proceed from here.
Please let me know if I can be of further assistance.
The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.
When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.
It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.
