    Could this problem be the color wheel or power supply. Does anyone have an idea. Again, the tv warms up the screen is black with no sound. I hear the fan and another noise humming that goes lound and then goes low up and down for approximately 1 minute. The tv then shuts off with the lamp indicator goes to a solid red.

Hi and welcome to FixYa,

Always, any sound out of the ordinary indicates a fault; intermittent clicking - relay, chirping - power supply, screeching - high speed motor.

Two ways to address the problem:

  • DIY (do-it-yourself) repair. This would require familiarity with electronic components & circuitry, use of a DVM/VOM and a soldering iron. It would be to your advantage to have access to a Service Manual or at the very least a schematic diagram with voltage measurements;
  • seek the services of a qualified professional for a repair quotation.
While it would be possible to effect your own repairs, there would be the above mentioned pre-requisites; otherwise, it would be guess work and unfortunately may lead to false diagnosis/parts replacement. A quote on the other hand would cost depending on the going rate within your location. The advantage is that you would have an idea of the possible cost of parts and service fee. This would be significant since this information factored in with downtime, efforts to have the TV repair would present you an evaluation of your options to consider including, DIY, repair person or worst, replacing the unit entirely.

If you are comfortable with the DIY, pls post back. Good luck and thank you for using FixYa.

There is a safety latch where the lamp door closes you have to make sure that the latch is getting depressed when you put the lamp in if not the set will not turn on, some people have stated the when they change the lamp that the latch is not being depressed and the set will not fire up.
thanks.

The noils lets think to a fault concerning the power supply.

If no blinking code is given the tv must be taken apart and tested by a technician.

On PSU board, capacitors and components must be tested.

If problem is not there , get the service manual and follow troubleshooting diagrams.

Hello

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
OK.

Heard a loud pop noise and the tv cut out. Left it off to cool down and turned it back on but no sound or picture. The green light was on and the fans attempted to start but then shut down


Easy one. Your lamp needs replaced. part number is labeled on the lamp itself and is easily accessed from the rear of the TV. Approximately 6" lamp cover removes with a few screws then a couple more for the lamp. Simply pull out and replace. Cost for the lamp is around $219. Make sure to replace with OEM parts.
