Samsung LNR 328W TV turns itself off and turns itself back on

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.

CAPS (capacitors) on the power supply board are going bad. TV putting itself into fault protection by turning itself off..... If you can give the model number I can better help you.....

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

lamp, ballast or colorwheel

Replace the lamp - they only last about 2 years with 4 hours use per day.

Might be overheating and might need a firmware update. I'm guessing overheating.

Hello LNR328W
You have a bad T-con board. This board is mounted directly on the panel. Its located near the top of the set in the middle. This part is sold with the panel which makes it expensive. I have a few T-con board in stock. Let me know

90% of the time this is caused by a bad LCD panel. The other 10% is caused by a bad Main board. You may want to try and change the main board first. This set carries 2 different type of main board. You MUST look at your Version Number located on the side of the unit. (Version AM02 uses BN94-00667S.Cost $177.81) (Version 0001 uses BN94-00629R.Cost $176.14) LCD pane BN07-00194A Cost $806.49
