    +Everything was fine when we turned the TV off last night. Went to turn it back on today and the power light just blinks 3 times and quits. We recently stopped our direct TV but we've been able to watch DVDs since then. Can't figure out what the problem is. Any help is appreciated.

Sounds like the two large caps in the psu have gone slightly low in value and may need replacing.

SHARP LED TV does not power on


Sounds like main board fault. 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.

I have a Sharp 70" (LC-70LE632U) LED TV. When you turn it on, the front led is on, but no screen. After a few seconds, the front led starts 5 short and 2 longer blink and continue this way constantly.

Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

Good day!!!

That problem is usually cause of bulged capacitors on the power supply board..

This the sample picture of your power supply board and I marked the possible problems on capacitors..
2_2_2012_2_50_18_am.jpg
Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps..

Tv sony stop after 20 min standby led flashes 3 times


HI,
By three blink it means the B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is because there is problem in the power supply circuit. Check for any dry soldering in the power supply side. If the tv is working properly for 20 minutes then its sure that there is some dry soldering joints in the power supply side. You have to resolder suspected soldering contacts using soldering ion and solder. The dry soldering joints will look like on in the picture.

42 inch philips lcd no picture no sound


Sometime a no picture, no sound still has the power light or some other led blinking. The blinks might be an error code that will isolate the problem.

In general on LCD TVs with no picture, no sound, no blink code, the main power supply has failed. The capacitors weaken and when bad enough, damage the power supply.

If there is a blink code, the most, if not all of the power supply is OK and the blink code could point to the problem.

TV turns off by itself after being on for 60 seconds


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

Toshiba TV


Will not power, led blinking
check R640 (1K 1/4w) if open replace ic600 (8-759-670-30)
Standby led blinks slowly, a few times, chassis won't start up
I changed the vertical deflection ic type TDA8170 and I measured two leaky capacitors in the power supply. Better to change all 4 capacitors in the power unit, everything was then ok !
