About three months ago I replaced the convergence chip in my T.V and everything has been working fine, until yesterday when the power went out to my house. I was watching the T.V when the power shut down and then cycled about three times within a couple of minutes. After that all I got was a flashing green indicator on the T.V. I tried unplugging it several times for different durations but still nothing. I then opened the back and checked all the fuses including the DM module and all check out OK. Any suggestions on where to go next? This is a WS55511 about 4-5 years old.
