Hi everyone,
Having some difficulties with my 70" Sharp TV purchased around 3 years ago. Model number is LC70UQ17U. Around a month ago the image on the tv occasionally started flickering pretty severely:

If you restarted the TV the problem would go away. Around a week after it first started, however, the TV shut off while we were watching it and it won't turn back on. The front light blinks in the same pattern repeatedly -- three long blinks, pause, one short blink. Based on some research I did it sounded like it might be the power supply board, so I tried replacing it but it didn't work, still have the same blinking pattern. Then I thought the replacement part I had been shipped may have been defective, so I ordered another new one and it didn't work either.
Someone pointed me to the service manual, and they found this:

Anyone knows how I'd go about fixing this, or if it's fixable? Thanks a lot
