The standby/power switch should be flashing in a repeatec count. Please post that count. It is an internal diagnostic that will tell us the problem with the set and thus the actions required to repair it.
1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.
With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.
your flyback is bad on the D board thats what makes the led blink 8 times replace the flyback and you should be fine. If you need a link on where to get the flyback and instructions on how to change it let me know and I will post a link
That code means that the +5 line is either overloaded or shorted on the A or B board. It may be worth repairing if the shop is an authorized Sony repair shop as they will have access to the Sony TSS logs and should be able to repair it without much trouble.
sounds to me to be a shorted HOT transistor or short somewhere.
the click sound is the switch mode power suppy powering up sensing a short and quickly shuts down. the hot transitor is mounted to a heatsink
near your flyback. check for emitter to collector short. you can try replacing it if shorted and if lucky that all that was ..but if shorts again you looking at probably a bad flyback.
TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR
The STANDBY light is flashing on the television and there is no picture or sound.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
Turn off the television.
IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television 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 television.
Turn on the television.
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.
