Y-sustain drive should be checked. These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can vet an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts.

Sony trinitron kd-34xs955 standby light is blinking 7 times


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
As you can see here, seven blinks of standby light is due to some over voltate at the final anode of the picture tube. This is a protection process that going on insde the tV circuits, to prevent more damage to other comnponents on board. The most common cause for this is with the main power regulator out voltage itself. If any way, it ahs exceeded 135VDC, this kind of fault will occur. Check the main power regulator section circuit for any damaged component/s. Replace all the small electrolytic capacitors there. Visit the site named 'Electro-help' for more details. Check this LINK and select the site named above. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy. Some times, the ads attached with each posts might help you to find the availability of spare parts. There are more than 550 posts to different brand TVs. Blinking codes and details are there.

2004 Sony 52" Wega dont turn onnthe stand by light stays flashing. This TV first started by taking long to turn on and now and then would turn off until one day it just didnt turn on and the standby button...


When that model Sony shuts down the LED starts blinking as you say but it is telling you something because it blinks a certain number of times and then pauses and repeats the number of blinks. Count the number and then I might be able to help you narrow down where the trouble is.
