Toshiba Model 42HM66 DLP Projection TV

TV is approximately 2 years old. When I turn the TV on I get nothing but a blue screen. Could this be the lamp assembly?

I strongly doubt it's the lamp assy since you can actually see the blue screen. If the lamp failed, you would not see anything on the screen. This blue screen indicates to me that either the tuner is no longer decoding the signal, in improper input has been selected (ie: input 1 is selected while actual signal is on composite 1), or something of that nature. If you are getting audio then the input is selected properly but the video decoder has failed.

If your cable signal is going through a VCR or DVD, disconnect it from there and go directly to the TV (ie: bypass the VCR/DVD). If your picture comes back, there's some kind of problem with your VCR/DVD player.

If you have multiple inputs, try connecting an input signal to another input (ie: video 1, or aux from a dvd player) and see if you get a picture there. If you do get a picture, the whatever input you're currently using has malfunctioned.

Could be the power supply. You can check the power from supply with multi-tester or voltmeter. If have a service manual, then I suggest testing the ballast as well

14 MONTH OLD TOSHIBA TURNS OFF BY ITSELF


I repair a lot of these and a average tv lasts like 3 years . It is not like the old days. I suspect the lamp or fans or therm protector.

I would call a local tv shop see what they charge for estimate it might be worth his estimate to find out what it is.


Thanks doctor video
