Keeps turning off by itself after about 30 minutes

Sounds like your lamp is overheating...possibly because the fan is not workign or clogged...or the thermal sensor has is failing...google both topics

check the tv by takeing the tv to were you bought it

this is a bad color wheel, however you cannot just change the color wheel on this set you have to replace the entire light engine.

the fan sound your hearing is the berrings in the light engine you will need the engine replaced

Sounds like a fan getting cought on some dust inside you might want to have this serviced if you do not know how to clean it.

The humming would be a fan the buzzing would be the fan getting stuck!!

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

bad lamp google for part 3

Your light engine is going bad. Toshiba part# 75003333

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
