When you click on the power of our samsung tv, it takes 15 minutes before it actually turn on. what could b e the problem and how do we fix it?

Hi,

please pull the power plug out again for 15 minutes before powering on the tv. Now, you can remove any unecessary accessories and watch for any issues within the next week. if an issue occurs, please re-do the 15-minute fix and then attempt to update your tv's software. If the issue occurs later, you can re-do the 15 minute fix and then factory reset your tv.

Thank you.

Give it up, stop the bleeding and frustration and replace the TV.

Samsung 46" LCD TV (LNT4665F) turns off and on over again -

You likely have the infamous Samsung capacitor problem. A capacitor(s) on your power supply board has failed, or is failing. Youtube has several videos (search "samsing capacitor) that are generic to Samsung TVs, showing how to identify and replace the failed capacitors with parts that are readily available. What it takes, more than anything, is soldering skills. I own the exact same TV you have (P3F variant), and have fixed it. I'm an electrical engineer with the parts available in my basement, but for me, the fix took about 15 - 30 minutes with the most time removing the back cover, plus if you don't have the parts, a trip to an electrical parts store or Radio Shack, or an order to DigiKey (less than $10). Some have reported that haranguing Samsung customer service brought free fixes even though the warranty has expired. If all else fails, I'd be willing to repair your power supply board, but you'd have to mail it to me and I'm not sure how contact info is passed on Fixya.

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Ur tv the Ballast board the help to turn on the tv projection bulb is dead.Try website like Tvrepairworld.com to buy the Ballast board for the replacement.The Samsung/Akai tvs use the same Ballast board.When in the website go to the menu that said Samsung/Akai circuit boards.Pick that option click on it,u will see a picture of a Ballast board look like.

I have a Philips 60" Rear Projection, and all of a sudden I have no picture or sound. I push the power button, and all it does is click. It will keep clicking until I turn it off. Anyone seen this problem?

you have a couple of caps going bad on the power supply. look at the power supply and you will see some caps puffed up on top just replaced them with some of same value.

Hello Ruben,
This type of failure is common on these TVs. The power supply might need to be replaced due to bulging capacitors. If you are able to replaced the capacitors, it is a cheaper alternative.
Check the link below to find service parts.

If you mean the actual mains switch needs multiple cycles, it could be faulty.. does anything, say a power indicator, come on when the TV doesn't?
If the actual switch is OK, then you probably have a fault in the power supply section... often faulty electrolytic capacitors. U need service.
