TV will not power on. Can't tell if it is off or on - no picture. The standby button flashes 4 times then pauses, then does it again. When you push the power button you can hear it click several times but nothing happens. we bought the TV in 2003. is it worth getting it repaired??

The Standby light flashing that you see is the built in diagnostic program signalling an issue. This particular one means that the D board is not getting the 15 volts it needs, and normally IC5004 is causing the issue. It has been awhile since I dealt with this repair and I therefore have no idea what it will cost you to have it resolved.

If you have some experience working with TV's you might want to take a run at fixing the issue. You would have to ensure you have the tools you need as well as a copy of the service manual, which you can purchase or download of the Internet. I would not advise trying the repair yourself if you have no experience with the inside of a TV. There are lethal voltages and amps inside that must be dealt with in the correct way so that it is safe to work inside the TV.

I would suggest calling your area Sony repair shops, let them know what the flashing code is and what it is signifying, and then asking them for a quote to fix the issue. As most electronic repair center charge from $85-125.00 an hour for labor I would get an estimate and then decide if it is worth fixing, or would it be less expensive to buy a new TV.
