To all who are having power supply issues: Samsung is now acknowledging a problem with faulty capacitors. I called 1 800 726-7864 and they said they would repair certain out-of-warranty TVs if the problem is related to the capacitors. I just called and they are sending a service rep out to diagnose the problem

SOURCE: Samsung 40" tv won't turn on

i had the same problem, you'll have to call the samsung service center. You TV's part which looks after the voltage connectivity has failed. This majorly happens due to voltage fluctuations. The part will cost around Rs. 2800 and service charges will be applied by the company.

SOURCE: 3 year old Samsung 40 inch LCD TV will not turn on

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

Is it worth to replace the LCD panel ?\ The Replacement LCD panel code is BN95-00604A How to do the LCD panel repleacment


Considering the price of a TV I'd say not.

Did a google search and found this site using BN95-00604A: http://www.encompassparts.com/item/9186449/SAMSUNG/BN95-00604A/PRODUCT_LCD-AMLCD where they list the part at 565.00 including a 102 core charge which I presume would be returned to you once the core is received. It is unknown if this source is the only source, that this source would actually sell the part to anyone other than authorized service providers, it also doesn't address shipping costs or taxes and damages that may occur in transit. Also from this site, I learned that this part is used in a Samsung UN40ES6100FXZA 40-Inch Led 6100 Series Smart Tv
Here it is on Amazon for 829 with free shipping: http://www.amazon.com/Samsung-UN40ES6100-40-Inch-1080p-Black/dp/B0076M04QU

My 40 inch LCD sanding tv won't turn on for awhile. It keeps doing the clicking sound for about two minutes before it catches and turns on. Shat should I do?


> Shat should I do?

Take it to a qualified TV/video technician, for proper trouble-shooting and repair, because this problem has no "end-user" repairable parts.

Samsung LCD 40 inch LNT4061


Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.
