Sony triniton 37 inch flat screen ( five years old)
The problem I'm having is the set-up screen keeps popping up at about
10 second intervals. I have tried unpugging the tv, pressing the menu button on the remote, and the display button. This only shuts it off for a few seconds. I had this same problem about two years ago but it stopped
doing it after a day. Can anyone help with this problem? I would appreciate any advice.

Re: sony triniton 37 inch flat screen ( five years old)
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.

Sony has a feature called a shut down circuit. If the standby light is blinking at (1-2 ) second intervals, you have a possible power supply drawing excessive current. This TV would require further diagnostic evaluatation . Not a 75 cent fix Good Luck with it.
The continuous blink code indicates some failure in communication between the computer in the set and the big signal-processing chip that controls most of the TV's video functions. Since the set fell, it's probably due to a either cracked circuit board or a broken picture tube.
If the board is cracked, it might repairable if the broken circuit traces can be found and patched. If the tube is broken (because the shock of the fall cracks the glass neck of the tube and allows air to leak in), it's time to replace the TV.
There's really nothing you can do on your own to fix this. Your best bet is to see if a professional can come out and give you an estimate. (Or use this as an excuse to get new flat-screen which would take up a lot less room!)
For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.
I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
The 7 blinks indicate a high voltage shutdown (high voltage exceeded 33,000V). This is usually caused by a defective regulator. Could you please post the exact model number (KVxxx) and I'll look up the part you will likely need?
How old is your TV?
TV's have a circuit that monitors the high voltage and shuts down the
set if it senses something amiss. If the set is at least 10 years
old this is typical and not worth repairing. If less, figure on
replacing the flyback transformer.
Hope ya fix it!
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.
