Sony CRT frozen on cross-hatch pattern (help!)
I have a Sony KD-34XBR970. I asked a technician to look at the set and make some corrections. He connected his Leader LCG-397 pattern generator to display a cross-hatch pattern, and now the TV is frozen on the pattern. We can only turn the TV on and off and enter the service menu. Nothing else. Even when the generator was turned off and disconnected, the set is still frozen on the pattern. When we power down the TV and power it back up, we see snow for a few moments before it returns to displaying this cross-hatch pattern. We have done everything to get out of this. Any help?
