Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board..

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.

Where is the power board for a phillips 50inch model #50pl9126d/37


Hello

As far as the lamp stays lit for a few seconds, all other voltages comes to the lamp and inverter board are OK. If the lamp has reached its life time, this type of fault can occur.

Sharp lc-32sb220u lcd tv. Green Power LED flashes steady


Okay, I found the problem. There is a problem with the
ccfl (lamp) groung PCB. Mine is completely burnt through. I am going to attempt to repair it, but will likely need to extract it from a different unit. This board is on the front right of the lx in the lamp housing behind the
lcd panel. What is happening: The inverter circuit on the power supply is detecting that one of the lamps is not lighting and it goes into shut down.

Hope this helps!

If you just replaced the lamp then there's something wrong in the power circuit or you have a bad lamp. If you can I would take the back cover off and look at the board where the power cord connects and lok around it for swollen capacitors. Let me know if you find anything.

Replaced bulb in Mitsubishi WD-52525 and it still does not work


Press the input/device button and the menu button at the same time. Green LED will blink a two digit code blink 1st digit short pause blink 2nd digit longer pause and repeat. Any number of problems can cause this same symptom.

If the red LED your refering to is the Status LED and not the Lamp LED then you have big problems. A red Status LED indicates no communication from the Format board to the DMD board (light engine). 1/2 the time caps on the format board itself the other 1/2 must send entire electronics package to Mitsubishi.

Status Light Flashes Red


first did you getthe lamp from miths and if notyou could have bought a bad lamp. you need to get a lamp form mits if you did not buy from them. if you did buy from mits have them replace the lamp it has a 90 day warranty. try hitting the menu and device / input buttons for 5 sec and repost the blink code. it is a 2 digits blink code. (ex. 23 or 33 or 26 like that)
