THIS PROBLEM COULD BE SOLVED IF THE LIGHT BULB IS CHECKED FIRST,IF THE LIGHT BULB IS FOGGY REPLACE IT PLEASE.

Lamp inside of your TV set is nearing end of lifespan. Replace it.

replace the lamp. . thats all . and make sure to put the lamp door back on of course.

I may be late with this but it souonds once again ike dust in and on the bulb cage. These TV's will turn off by themselves if they over heat. The extra dust(not much) can/will cause the TV to heat up and shutdown for a few seconds to a minute. Depending on the time of year and location of the TV can vary.

Try removing the bulb and cleaning it with compressed air and a micr fiber towel. Of course don't touch the blub itself as the skin oils will cause it to break.

This could be caused by dust on the bulb. Dust can cause the unit to over heat and will shutdown for a few seconds to a minute and then come back on when it has cooled down. This time can vary depending on the location of the unit and the temputure in the house. The dust becomes hot and so the Thermal unit shutsdown for a short while and then comes back on.

Clean the bulb by removing the cage and using compressed air and a micro fiber towel and install back intot he unit. Make sure you follow the Sony Maunal. Also make sure not to touch the bulb as the oils from your skin will cause it to burn out quickly.

Try taking off the back pannel and spray compressed air on the fand and lamp. There is probably too much dust in the fan and on the lamp, triggering a sensor to go off and you loose your picture. If the sound goes off too, then it my be something more techmical. My tv had the same problem. This is how I fixed it. You can also try replacing the bulb. They are at least half price on the internet than they are if you buy them at a local retailer.

its the bulb i have the same problem with that model the service tech said life spann on bulb is 2years he replaced it fixed you have to readjust all the pic settings because new bulb make pic too bright

I finally wet out and bought the tv repair manual. Thought the problem had to be more than the bulb because i was losing sound too. Everything in hte repair manual brought me to the bulb or the ballast. I ordered a replacemant bulb. I spent about 150, which included overnight shipping. I replaced the bulb just before Thanksgiving and haven't had any problems as of yet....
