Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?


Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

TY-LA1001 Timer reset

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Hi, Our Sony Bravia TV model number KDF E50A11E is not working. There is a red blinking light flashes three times and then goes green and then red blinking again after about 3 seconds. Is this a bulb...


On that particular model I believe there is both a lamp indicator light and then the power indicator light. If it is lamp related the lamp indicator light (LED that looks like a sun in a cup...) would be on.

If the power indicator light is flashing red to green, that is a self diagnostic code, and you will have to contact an authorized Sony repair fascility for them to translate the problem. The error codes are not listed in the user manual, since most are not user serviceable.

Replaced both bulbs with brand-new bulbs. Now all


Verify that the lamp doors are securely closed. The blinking red lights indicate a lamp problem. In this case, both appear to be defective. I doubt that the lamps are the problem. double chack all connections and doors for proper seating. Update this if the problem remains.

Thanks,

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

NO PICTURE OR SOUND


Hi
Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here

Hope this helps

Sony Wega 55" Replaced Bulb TV still does not work


Hello, please check how many times the red light flashes. If it is 3 times this means that the lamp cover is not fastened securely. If the red light flashes 5 times this means that the lamp driver is defect. If you need more help please advice
