My guess is the power supply has failed, especially if the standby light is off

I have a Samsung LN52A550P3FXZA. The TV does not come on.

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.

Why wont this model stay powered on

I spent 4hr this morning trying to fix my Samsung t.v. I replaced the bulb, cleaned entire insides of t.v., checked if both fans were running, yes, checked for any corrosion or disconnects on boards/wires the best I could, I read several internet sites an kept checking what was suggested, then I found this one, I disconnected the blue & white sensor wire from top connector(right above the bulb casing). I put one end of a piece of wire in each of the holes -2 holes, it didn't work.. I tried several times...I took my piece of wire out and plugged it back into the sensor, then I unplugged the blue and white from bottom connector, this had 3 holes.. I separated one side of my 1 piece of wire (rope type) into 3 and inserted (snugly) into coupling and my tv is now working fine. I had to try this a couple times and discovered that I didn't have my wire pushed in snuggly. I will replace temp sensor, still need to figure out if I need to replace top or bottom panel, I'm guessing the bottom panel ?????? The standby light and bulb light are both off now, yay. I have a large Samsung t.v. I think 52" that I purchased from Circuit City around 5 yrs ago, model # Hl85086W. The problem I was having; Standby Light was on when I'd turn the t.v. on, would hear a low Beeping Noise from back of tv, the Lamp Light would come on I could hear the t.v. would try to turn on and in seconds the t.v. would just Shut Off, Both Lights would stay on, I'd unplug and plug back in and try again and get the exact same thing, Both Lights would come on/ stay on, t.v. would try to turn on and Automatically Shut Off. Thank you krimi !!!, for taking the time a year ago to post this. Very Grateful! Robin from Indiana I hope this helps someone else.

My Sony wega tv won't turn on goes into standby red light blinks 10 times then shuts off?

Look at the owner manual as the 10 blinks is a error code or Google the model number to locate that information--Sony error codes are general and often misleading.

I would if looking at the set inspect the lamp first.

Sony HCD LX20i audio shelf sysyem won't turn on. Standby light flashing. Disc stuck in it.

Check the speaker wires for shorts, if okay! suspect the audio output ic's, the protection circuit won't come out of standby because there is a short.

My samsung 40# shut off and won't come back on model# LN40B500P3FXZA please help

set has a shutdown or failsafe circuit:

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.

Samsung T220hd won't turn back on from standby

Power up issues on the T220HD monitor are caused by a failure of the capacitors on the IP-49135b power supply board that this unit uses. The repair is easy, you just need to replace the 7 failed capacitors and the unit should be as good as new. Here is a link to some information showing what needs to be replaced to repair the power supply board.

I hope this helps.

The Samsung HL-S5086W turns off after about 20 seconds. The Standby/Temp, Timer, & Lamp lights will blink simultaneously and then it shuts down. We blew it all out to clean the dust, removed the back...

Because the problem was the lamp. The unit will not power up unless the faulty lamp's replaced with new one. Click this LINK to buy online.
Hope I helped you.
Have a nice day!
Thanks for using Fixya
