We have a Samsung 1080p TV model LN40B540, the picture seems to go on and off but the sound is just fine. What needs to be replaced? Is it worth fixing? The picture goes off about 10 minutes after we turn on the TV....

SOURCE: Samsung LTN1765 has blinking green power indicator, but no picture or sound

Try replacing C51, a 10 microfarad 16v. surface mount electrolytic. It's near IC23 on the upper center of the board.
This part had high ESR on a couple of sets I serviced which
kept the power supply from starting.

SOURCE: samsung plasma ppm42s3 , picture wobbling,sometimes screen goes blank

Hello arunaik_6,

This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.

I hope this helps,

Thank you,

Samsung TV model un40eh53000fxza have sound but no picture


It all depends on the connections and cable.
If you are using a HDMI cable and have sound but no picture, then your TV probably needs to be fix.
if you are using a RCA cable or component cable, make sure that you have the correct TV input.
you don't specify what type of TV you have, but if I were you, I'll check the connections first.

How to fix TV


If you are willing to take a chance...and you have some technical skills you may be able to repair it. I was able to replace 2 capacitors on my power board for under $5. I had no picture, no sound. Not saying that is what is your problem. Search the internet for your model number and no picture. I see several youtubes on yours as well.

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
