Question about Televison & Video
I've seen solutions to this problem for other models, but want to make sure it is the same for mine.
After unplugging my ws55909 before a lightning storm, I'm getting error 22 (short circuit protection). Ironic. It was working fine before and this is what happens when you're cautious. I Should've left it plugged in!
The only other thing that has happened before is that occasionally the convergence won't load at power on and be wayyy out. Shutting down and turning back on always fixed this. One time, it didn't and I re-set the grid and convergence from the service menu. Don't know if this has anything to do with my current problem.
From what I've read, the DM board is to blame? Another forum breifly stated that only malfunctioning low voltage supply will cause error 22. I have the service manual, but like others have said, it doesn't even tell you where to start troubleshooting with this problem.
-- Thanks --
1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT
