I have some problems turning MY 1999 50-inch Sony Trinitron KV-34XTR10
When I turn on the TV, the led blinks and I have the audio, but the picture does not appear until some time. First 15 minutes, then worsened to nearly 1 hour. Some forums attribute this problem to dirt, so I opened up the set and did a bit of cleaning, but I had not any luck. I did not disconnect the flyback to clean the connection to the tube because I was not sure how to discharge it first. Is this related to dirt, or do I have to change the flyback? Is this problem caused by something else that I ignore??
Thanks for your help in advance!!!
Is this a good question?
