SOURCE: Power light blinks

I found a solution, Heat. When the set is on and heats up it stays on, but once off for the night it gets cold and can't start, try using a hair dryer on full blast and put the heat around the back top vent like structure and wait for the light to stop blinking, this only takes about 2 min or so

My lg 52ld 550ub, has a problem . No picture, on lg logo comes on and red blinking light


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.

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.

Samsung TV won't turn on. Red light is solid, won't blink when pressed. All capacitors seem fine (none swollen or vented).


That model is covered under a class actions lawsuit settlement over bad power supply boards. You need to contact Samsung about this and get a warranty claim started, even if the original warranty is over the settlement terms will cover parts and labor. You can get additional information about this along with contact information here: http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

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
