Question about Projection Televisions

1 Answer

My samsung sp50l7hx dlp tv wont turn on,last night i fell asleep while watching and awoke to see tv switch off then back on by itself, colour was dull, this morning i tried turning unit on. it started loading up i heard speakers switched but no sound & no picture, the unit switched itself off then on about 3 times with no picture coming up then in the circle on the front it had a warning symbol come up with a picture of a small light globe under it. i automatically thought the odvious, the bulb has died. so i rang a few tv repairers to see if i could get a bulb. one told me that it may not be the bulb. it could be the power supply to the bulb. i don't know wheather he is just trying to make money from me or could this be the case. i have had unit 3 years and have misplaced the user guide with the troubleshooters guide.please help i am having big tv withdrawals already.

Usually when that symbol comes up it means your lamp is defective so I would replace the lamp because if you had the set for that long and not replaced the lamp chances are thats your problem and you may be able to get a user manual for your tv by going to this sight

I have replaced the bulb but still it will not turn you can hear everything start up but it seems as not enough power to light the bulb help please I have a samsung DLP SP50L7HX it still shows the bulb...


Hi,Sometimes its something simple.Did you close the door cover,it has a switch that wont let lamp power on if its not pressed.Did you reset the lamp timer? you can do this by unplugging the tv wait 5 min and plug it back again.Any strange noises like clicking or buzzing sounds? If you heard clicking it will be an issue w the board that powers the lamp its called the ballast.If you heard buzzing it could be an issue with the color wheel,which is a small disc that creates tyhe colors on your tv. Last question did you get the Original Philips lamp or a generic? If you got a generic send it back for testing or get refund and get yourself the original.Email me if you have further questions at r2d2repair@gmail.com have a blessed life!

Samsung DLP 62 inch turns off by itself after being switched on


take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

Sony 46" lcd turns off by itself and will not power up again.


Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.
