Went dead on me. At power on, I can hear relays click and a green led on one of the PCBs is "on" when Powered on. No audio, no picture. Am waiting on schematics. Any ideas where I need to start???
The problems I have found with this Mitsubishi has been mostly poor solder connections and shorted horizontal output transistors. A couple of times I have had shorted horizontal output transistor, along with a bad flyback transformer. I have had IC302 be bad a couple of times, causing the set to go dead. Also D707 has had a high resistance leakage a couple of times, R995 has changed value, and have had C736 open up and cause the set to not start up. There could also be the main regulator IC in the main power supply could have failed. Good Luck with the repair of thei TV set, and please let us know if you fix this TV and what you find the fault to be.
