These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

50PF9631D won't turn on... red light flashing/blinking 6 times


Your TV main board is damaged and you need a new one. You can order one on ebay and fix it yourself. Make sure you have the TV model/serial number on the back label of the TV to have the right part when ordering.

I have a Panasonic TCP55GT30 and the red power light flashes seven times.


I also had the 7 blinking lights and no picture on my TCP55GT30 16 month old TV. The diagnositics show a bad SC board. Panisonic will cover the cost of the board only. The $350 labor charge is mine to eat. I spoke to Panisonic and they basically don't care. They know they have a problem but aren't willing to accept it and recall the boards or cover the total repair cost. So for me I think the cost (25% of the total cost of the TV) on top of what I already paid for the TV is rediculous. This was supposed to be a state of the art, top quality TV, which it obviously is not. My $300 Emerson flat screen, 4 yr old TV work just fine. I wil never buy another Panisonic product in my life time. I understand that things go wrong with anything, but the difference is how the company handles the problem. Oh yeah, my brothers did the same thing at 12 months. Real quality.

Tv will not come on. Red light blinking on bottom left front. Red light blinks 7 times


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.comj

Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
