Every 30 seconds, screen goes, dark, sound goes quiet for 20 seconds, then comes back on. Can a bad lamp cuase picture and sound problems? TV is 3 years old tomorrow.
I have a sony KDF-E60A20 projection tv. The picture would go out for about 30 seconds and come back on. It would continue to cycle this way. The green power light would stay on and not flash. The sound would go off when the picture went out and come back on when the picture came back on. I tried taking the bottom cover off the back exposing the fan and blowed it out with a vacuum cleaner, also taking out the bulb and blowing it out. That didn't help. So I ordered a new bulb from Advancedlamps.com and that's what it was. I have now had it on and off for two days and no problems. Cost of lamp was $107.00 including shipping. Good Luck!
This may be a problem with the power supply board losing power and coming back on intermittently. This also could be a problem with the control board having the same problem. This unit should check thoroughly by a service technician for bad components due to overheating and aging You can go on to the Sony website at www.sony.com. Go to the support section and put in the model number of your television and check the frequently asked question and troubleshooting sections to see if some has had this problem and had the solution posted.You can call Sony television service number at 1-239-768-7547 for technical assistance. I hope this helps you with your problem.
