Customer Question

Sony LCD Projection TV Model #KDF-E42A10. Sometimes when turning on, the green indicator light blinks indefinitely and TV doesn't turn on. Turning it off and then back on usually corrects it after one or two tries. No problem with picture once it turns on. Sometimes you have to unplug the set before you try turning it on.

Thanks for the info, this kind of symptoms appear when lamp in TV has reached at end of working hours lifespan but not dead/ broken yet. Since lamp has never been replaced in TV (it is 2006 year model) so it seems it's time to replace it in TV to resolve the issue, in other words lamp is about to die/ broke and new lamp will help to get the TV back in business.

Lamp replacement is easy and procedure is written in TV user manual, click following link to download copy..
