Recently my TV picture and sound would go blank and the power/standby light would flash green. It would flash continuously until the picture and sound came back on. It would go blank for about 10 seconds, then be ok for about 5 minutes. It;s a continuous cycle. Picture good for a few minutes, then fade to black. I tried everything the sony website recommended, including resetting the TV. I really don't want to pay the big bucks to have it repaired if the only problem is something simple. Could it be the Lamp is starting to go out? Please help. Thanks

The self-diagnostic function of the projection TV will cause the STANDBY
light to blink or flash when the television detects an issue. The number of
times the STANDBY light flashes corresponds to a specific issue. As per the two
examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in
sequence, the lamp cover is not securely attached. Reattach the lamp cover to
resolve this issue.
If the STANDBY light flashes four times in
sequence, the TV may be overheating. To resolve this issue, ensure that the back
of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash,
follow the steps below to perform a power reset:
Turn off the television.
IMPORTANT: For a
projection TV that uses an internal lamp, wait 5 minutes after turning off the
TV to allow the lamp to cool before continuing with the following steps.
Unplug the TV power cord from the electrical outlet.
Let the TV remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the TV is plugged into
a power strip or surge protector, remove it from the power strip or surge
protector and plug it directly into the wall outlet. If the issue is resolved,
the problem is with the power strip or surge protector and not the TV.
Turn on the television.
NOTE: If the TV does not turn on
immediately, the fan may need to finish its cycle. This is part of the cooling
process for some projection TVs and is normal operation. After the fan turns
off, attempt to turn the TV on again.
If the issue is still unresolved after following all of
the troubleshooting steps, service may be required . Please note the number of times the
STANDBY light flashes and relay that information to the service center.
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here.
