Lamp goes off and on.

Suspect number one is not fan, lamp or Color wheel--optical light engine with dmd is.

Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.
TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™.
TEMP light is blinking amber A projector fan has failed and the projector will automatically shut down. If the problem persists, contact Dell™.

Possible that the lamp /lamp holder has burned. if the lamp is not lit then it is possible that the power supply has tripped due to a thermal shut down. Allow the unit to cool down , remove the power and then try again.
if there is no sucess then it is possible that the lamp/power to the lamp is faulty.

Hi,
Time to replace Lamp in TV.
Existing lamp getting weak and causing that problem, replace lamp and TV will be fixed.
Buy Sony original lamp for TV safety and lamp replacement procedure is written in user manual.
Thanks.

If the set shuts off then tries to turn itself back on then I suspect the lamp. The lamp part number is BP96-01472A. If it just shuts down and then you are able to turn it back on, then in most cases you have a bad digital board. The part number for the main/digital board is BP94-02262D...Please take a few moments to rate my answer. Thanks...

Has the lamp ever been replaced on this TV? If not it would be the first suspect. The next time the picture goes out look for light coming from the back of the TV where the lamp is. If you see no light then replace the lamp. Please take a few moments to rate my answer. Thank you...

Hi,
Please count red light flash again.

5 times flash shows Lamp Error.
6 times flash shows No "DD 6V " output (G1 board) Its bit technical term.

Need fuhrer help, please Post it here.
Thank you.

Remove the lamp and check to see if the connections of the lamp and the lamp driver(ballast) are ok or they look bit burned.Also the lamp should always be replaced first especially if is two years old or more.
Check to see how many times the error indicator flashes.If it flashes 5 times then the lamp driver is probably defective.
common problems are lamp and lamp driver(ballast).
let me know if you need more help.
Good luck.
