What's your problem? tv shuts down

in your problem i think power supply is the problem of your tv. try to call a tv technician. dont worry its affordable. if you confuse about the labor cost ask the technician before make a repair.

It sounds that the voltage output from its internal power regulator board is not proper. Check it.

This is a typical memory problem. Better refer it to a qualified service technician.

Ballast is possible if repeated lamp failure but I have a solution I posted several times for this type of problem that works and is simple to try:

does the power indicator blink when the set shuts down? If so thats an error code let me know the number of blinks and I will assist with the reason why the set is shutting down.

Hi Brian,

The operation LED indicators on DLP Projection TV's also act as 'Diagnostic Indiactors'.

The flash sequence of these LED's indicate the appropriate fault - you will need to refer to your User Manual which should explain what each flash sequence means.

Generally, most faults on DLP TV's relate to either cooling (fan operation), faulty/expired lamp, or even a loose panel (lamp door etc) somewhere is not correctly secured, causing a micro switch to trigger a shut down.

If you don't have a User Manual, try downloading it from the manufacturer's website.


Hope this helps......

Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

Check to see if the back of the TV is hot to the touch when it shuts off. If so, your TV may be saving itself with a temperature sensor. This feature will keep TV's from melting down literally.
If this is the problem. I recommend running a fan over the back of the TV. Some TV's unfortunately are poorly designed and don't allow for proper ventilation.

The lamp needs to be replaced. It's on the back and easy to do. I replaced mine about 3 months ago and it was about $182.00. Hope this works, I know it's hard to fork out that kind of money at this time but once you do the TV will be as good as new. Take care

Hi there stuibel,
is there any ticking sound that's coming from the inside? if there is than could be the relay (posistor)
that's causing your tv to shut down. need to replace that.

thanks,

George.
