It shuts its self off picture is still great everything works great it just makes a loud pop and shuts its self off i can turn it back on after a few minutes sometimes it shuts off again minutes later and sometimes it goes for several days it is a quasar projection tv

Might have popped an internal fuse

When my TV did this in the past it ended up being the color wheel. I had someone replace it and it worked fine. I asked it if had to be calibrated after it is installed and he said no. Also make sure the door switch is pushed down when you install the back bulb door. Sometimes this switch can go bad as well.

Check for any external shorting of the speaker wires. Check for kinks or cuts in the cable that feeds the speakers. Also check the posts or socket at the back of the speakers for damage or wiring shorting out. Proactive IT Support PC Repairs Laptop Repairs Custom Built PC Leading IT...

That pop sound was your lamp blowing up. The crackling you here now is the ballast trying to light the lamp. Replace your lamp.

It ur power board,Tries buy it replaced it ur self it pretty easy.

Color wheel you can get one at the following link with instructions on how to replace it

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Bill ,i dont suspect the control unit is the problem im going back to the loud pop you heard I would say the pop you heard was one of the elemants blowing and that the reason the the breaker tripped if you say the clock,timer and light functon are ok it more so points to an elemant in most cases when an elemant blows it breaks the circuit .but the other componants also work when you reset the breaker i think in this case bill i would call a electrician it needs testing,sorry i could not help this time bill,but do not hesatate to contact me if i can help you again.adrian

TV was on with no picture problem. Left the room and when I returned the picture was very dim. Turned system off and turned back on. Picture didn't change, but heard a loud pop from the back of the TV.

my guess is that that high voltage seals on tubes are leaking out high voltage from tubes if not probly sealed with silicon they will leak out high voltage.replace them and seal coorrectly this may fix your problem
