I have a Samsung 51 inch pn51F4500, and it just won't turn on. When the power button is pressed, the light comes on and off. Will this do the trick?

Does the TV make a clicking sound also? You may want to look in the back first and see if there are any capacitors with cracked tops. If so, this will likely work.

I had similair problem with my Samsung. I looked it up on YouTube.com and found that it was blown capacitors. Looked like and easy fix. Search Google and found that Amazon.com sold a capacitor repair kit. Also purchased a soildering iron and fixed it with ease! Under $30!! Good luck.

No sure. My tv was a lcd and the model posted is a Plasma. I don't know if the board is similar or what year it is. You may have to google it and do some more research. Most likely it should but can't be sure.

Dont buy the sansung they have a problem with their power supply. I bought one about a year ago it was great would have recommended it to anyone, but one day it just wouldnt turn on anymore. Did some research online to find alot of people with the exact same problem. Samsung was no help at all. In my opinion Sony makes one with all the same features even the upscaler buy it.

Unplug the power and plug it back in. If you don't see a picture, it might be stuck in the wrong video mode. If it is, you might not be able to fix it without plugging it into a television that supports the mode it is currently in.

Yes, it immediately turns on when power is applied, regardless of former state. If there is no signal on the (HDMI) input, it will power off within about 30 seconds. When it senses a signal it powered on and remained on unless it was turned off via the pushbutton panel or remote. Works very well and scales signals from 1080i, 720p, WXGA, and others quite well. Some resolutions look sharper than others. I liked 720p the best.

not sure...when you installed the battery was the unit plugged in or not? if it was plugged in, try unplugging it after powering it off, intall battery, then try the power buttonwhat happens next? is it just dead or do you get lights at all even for a moment? mine just worked and was not an issue.....did you dbl check the model numbers? and it fits ok, not wobbly?mine has been working like a champ....no complaints at all!!!!

My model Samsung is the 8000, but touch buttons are also on the right, and they never show up unless I choose to select and push. I would think your TV is defective...

Man, I wish I could help. I know mine automatically turns off when I turn off my LED TV so they are somehow synced already. I never did anything special when I set it up. I have a Samsung TV. I don't know if that makes any difference at all. I'm also using all HDMI. I'm thinking maybe it's the configuration of how your system is set up? Please do update when you figure it out as I'm getting ready to purchase a new TV to hook up with mine and I might just have the same trouble.

I bought mine for a Samsung and it worked fine. I believe that the power connections are the same but could not swear to it. Cheap enough to probably give it a try.

We just received out Samsung 32 inch TV and after reading these posts turned the back light 8. It worked for awhile but I think there is something wrong with these TVS. Anyone have anything else to try

This might sound crazy, but did you turn on the power button? It does not automatically turn on just because plugged into the wall... I've had mine for over a year now. Still working perfectly. Very happy. Good luck!

i guess calling samsung would be the best thing. maybe it may be a power issue. the tv does suck up a lot of power at start up. but then again 5 seconds is a long time. the tv should not take that long to come on let alone buzz

Yes, the light should turn on by plugging it in. I know because I own it. Try plugging it in to a different outlet. If it doesn't turn on, the product is defective

That happened with mine also. For me, holding the power button down for a ridiculously long time worked and it powered on. 99% of the time, it turns on easily now. Only once since then has it failed to power up normally. Holding the power button for the prolonged time was successful again. Best of luck!

Yes,just make sure the power button is on.It's the crescent shaped one at the top of your unit with the power icon.

i just took mine into the shop for the same problem, very irritating hearing it turn on and off all the time just to start, it would take like 10 minutes for my tv to finally turn on, the technician at the shop said the power supply was bad and i wasn't getting enough power to the main board to turn the TV on, 200 bucks later, I am happy, fix it, it is worth it.

I don't know if this is any help but you should be careful to hit the on/off button just once. This unit is molasses slow especially when you turn it on. You may be hitting the button more than once and accidentally turning the television back on.
