TV will not come on - power indicator light blinks red

These blinks (Flashes) are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check these link s

start by checking the power supply in the set and if not able to do that consider taking it to a shop for an estimate.

you will need to replace the lamp

part# A-1606-034-B

see the following web site:

red light blinking genreally indicates a problem with the bulb or the fan

Power light blinking red indicates tv got internal problem and went on protection mode.
Please count how many times red light blinks after 3 seconds long pause as it is an error code that has info about defective section in tv and will help me to suggest any solution to fix the issue.
Thanks.

i have the same problem

yeah, should stay red when unit is turned off, indicating there's power but it's doing nothing.

Per user manual:
Solid red - power off (standby mode)
blinking red - power off (now cooling)
blinking green - power on (preparing to light lamp)
solid green - power on

If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: missionelectronics@sbcglobal.net The cost is 375.00 and that includes parts.
Good Luck.

Having similar issue with my PT-44LCX65. Lamp blew and replaced it (last month), never figured out how to reset timer. Now red indicator light blinks once every 5 seconds and after about 4 minutes TV goes black.... Any ideas?

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
