I was trying to repair my tv wich previously had a blinking red led 2 times and it kept going. After shorting the sdm the blinking led changed 5 slow blinks and 3 fast ones wich in the service manual meant error 53 / the fusion chip.
After I heated the fusion chip with a hairdryer for 5 minutes it started working perfectly but after a day it stopped this time no led blinks even in sdm mode.
After probing the psu I have 3.49v and for 1 second I have at least 2 12.3v lines active the fusion chip gets warm in that second the led turns on and then the 12v lines start losing power...
