This TV came with a defective LED, I fixed it, now is working but has a high frequency noise. When I touch a transformer leg (the yellow one on the right) the sound decreases.

Re: Sony KDL-55EX640
There are no part numbers for the individual LEDs. There are plenty of strips in China though, my search engine is full of vendors However not everything is being shipped currently due to Coronavirus.Originally posted by ajshoe View Post
LEDs are identified by their size, colour temperature measured in Kelvin, voltage and current. Plenty of options to choose from on Aliexpress but again, Chinese shipping issues.Comment

Re: Sony KDL-55EX640
One thing to realize on this set is if the LEDS are bad - the set can act funny on startup and while running. This set would turn on, no video, and then after some time freeze up (video), then comeback on, and cycle several times until red indicator light comes on and blinks 6 times. Set would act as if shutting down and then rebooting.Comment
