Hi I have a SONY triniton 100hz digital plus tv, its about five years old and have never had any problems, but just recently it keeps turning off, I will leave it for a while then turn it back on and its ok for a while, then it turns off again. I finally got a TV repair man out, he seems to be baffled, he said deffinately not a conector problem. but would have to take it into the workshop.
Also when my tv turns off the standby flashes 5 times if this is any help
Model Number: KV-28FX65U
Its the BULB people! You need to change it every 3 to 5 years! I have had my sony 55" for 6 years... I had Best Buy come out 3 years ago, changed the bulb... it worked fine. Just started flasshing and shut its self off and back on again. Time for another bulb.

Re: SONY TV KEEPS TURNING ITSELF OFF!!
You have to take it in to get it fixed. Five blinks means AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the Cboard, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
Ok, my sony wega, 42 inch, 5 years old has been turning itself off. The light flashes for about 32 seconds and then turns itself back on, just to turn itself off again a minute later. I don't know what to do, not sure if it is worth taking in.
Thanx for the solution. About 2 weeks of not having the TV working it started working again. That was after I posted the message in May. It has now gone back to the same problem. It does 2 flashes. I will pass the info onto my technical hubby and get him to check it out or get it checked out. TV can be a pain not working when you have a small child in the house.

make it sure that the coaxial cable has its own signal! if your tv has a raster (sometimes blue) and it says that the tv is good, but if there's no channel at all then the problem is in digital converter or the connection of the coaxial cable comes from..you can also try auto programing but if the problem still occured then contak your cable subscription channel
First make the set have a hard reset. To do this, unplug the power cord for at least 4 hours to 6 hours (over night), and then try using the set. You will have to re-do the user setup. This will reset the internal programming and restore it to factory user defaults settings. Unplugging for a shorter period of time may not do the trick.
If the hard reset does not fix the problem it probably has a defective eeprom or a bad voltage regulator that feeds the controller IC-EEPROM IC's. In which case you will need a tv tech to dignose the exact fault condition and determine the failed parts. (There are about 120+ parts associated with these functions).
This can be a number of hours of work to troubleshoot. Then there will be the cost of the parts, if they are still available for this model. If the main IC/EEPROM has to changed, the complete factory alignments will have to be done.
