Hi.. i have a Samsung un32eh4003fxza and the picture has gone dim. You can faintly see a picture and the screen prompts are pretty bright but also dim. But the picture is barely visible. Just trying to pick a good starting point for repair. Your help would be appreciated.. thanks

What do you do if there is an image with the flashlight test? Would it be the backlight driver board?

iI have this exact TV set in this video.. A Samsung UN32EH4003F - UN32EH4003 And we have sound but no picture. Should I hook up a DVD player and see if there is a picture? I do not see any burnt out componets on both boards. From what you have said it may be the tcon board, is that correct? If so can it be tested? Any information would be helpful. Thank you.

I have a Samsung LT27D390SW/XU with sound but not backlit. It showed the image when checking the screen with a torch. I dismantled the unit to find that the connector onto the backlight LED strip wasn't soldered onto the board entirely. It was loose and hence why intermittent backlight power, which eventually failed completely when it fell off: https://i.imgur.com/1mqjfgd.jpg

Hi, I've got a Samsung UN50J5200AFXZA which is flashing all the LEDs periodically as soon as it's plugged in. No picture or sound. At this point I've replaced both the power board and the main board; same result. I also did a test where I disconnected the main board from the power board and it still flashes. Any ideas on what I'm looking at? The LEDs are bad? I suppose there's a chance that both power boards are bad as well. Any help would be appreciated, thanks

My TV looks exactly like the one on this video. It's a Samsung model number: UN32EH4003FXZA. Initially the TV would not turn on. When I opened up the TV I found three bad capacitors on the power supply board. I replaced these capacitors, but the TV still would not turn on. I saw another video on youtube that showed disconnecting the connector between the power supply and the main board, and if the LED's come on when doing so, then the problem is likely the main board. The LED's did turn on when this connector was disconnected so I acquired a replacement main board from a TV with a damaged screen.

The replacement main board looks identical to the original one except the TV tuner unit is slightly larger. Both boards have a placard with the number: BN97-05375B. Since replacement of the main board, the red LED standby light comes on, the TV turns on, makes the sound that indicates that it's on, and the backlight LED's light up, but it has no picture. None of the remote buttons (menu, source, etc.) have any affect, although the Red LED blinks when the remote buttons are pressed indicating that it's receiving the remote signal.

Just to be sure that I didn't still have a power supply problem, I checked the voltages on the connector that goes to the main board and got the following results: pin 1: 13v; pin 2: 3v; pin 3: 13v; pin 4: 13v; pin 5: 13v; pin 6: 5v; pin 7: 13v; pin 8: 0v (gnd.); pin 9: 0v (gnd.); pin 10: 0v (gnd.); pin 11: 5.25v; pin 12: 5.25v; pin 13: 5.25v; pin 14: 3.5v. These were obtained with the TV turned on, and are consistent with the voltages shown on the legend adjacent to the connector on the board.

The ribbon cable from the main board to the panel board appears to be in excellent condition and I was very careful with it while connecting and disconnecting. Interestingly, the TV behaves exactly the same with the ribbon cable connected to the panel board as it does with it disconnected. Do you think I have a defective main board, or perhaps a bad panel board? I appreciate any help you could provide, and will purchase what you think I need from you.

Best Regards,

I have a Samsung un55fh6030 When I turn the eco sensor to Off, the tv is darkest say 50%, low 55% Medium 60% and High where I have it 90%. I feel it's a bad or failing eco sensor issue but don't know where it's located . When enabled, the backlight setting can only go up to 12, anything higher the screen darkens to below 50%. It's strange that the brightest I can get the tv is when the eco settings are turned on three highest. Which is opposite from my understanding.

Hi Jimmy, I have a Samsung UE46D6530WS led tv. I replaced the t-con board because my tv broke down out of nowhere. I didnt had backlight/screen or audio. Now I do have backlight and audio because I replaced the t con board. What can I do to get a screen? Do I have to replace the main board too or something else? Can you help me out please. I dont know much about technical stuff so please use simple terms to instruct me. Thanks!

Hello! I enjoy your videos. Thanks for posting them. I have a Samsung UN55ES6100 LED TV. Upon power on, back lights turn on for about 2 seconds, then off. So, back lights do not stay on and flashlight test shows no image on the screen. Power supply is producing 5V & 12V, which is making it to the main board via the connector. Disconnecting main board from power supply results in back lights coming on and staying on continuously. Disconnecting all connectors from the main board, except for the cable from the power supply to main board, results in same initial symptom of back lights on for about 2 seconds, then off. No caps look swollen and no burnt components; however the main chip on the main board gets too hot to keep your finger on it for more than about 2 seconds. Thanks in advance for any help.

Jimmy. I have a Samsung UNF60FH6200F 60 inch LCD. I purchased the replacement Power board/LED driver BN44-00669A from you. When I replace the board and plug in the power (tv off) the board sparks and pops. It only does this when the connector for the LCD strips is plugged in. Never the connection from the Logic board. Can not find an explanation. Is the Board connecting to the LEDs bad? Wouldn’t think a blown LED would do that. TYIA.

Oops, I just send you a message to another video. I see now you explained the T-con is under or together with the screen?? can still be change??
This is the message I sent to the other video
Hi, and thanks for the video, they are very informative. I have a Samsung TV model #is un48h5500. I have a problem on the screen that started couple of days ago. There is a white spot on the screen, only one, in every input. I made a picture test and still there, is about in the middle of the screen to the right. I have a picture I can send. I call Samsung, they first laugh at me and then told me to call a technician. I work repairing computers so I'm I can replace a board, thinking that that's the problem. If you have an advice please. Im sure is either the t-con or the main board, do you sell those? which one you think is? If you have the parts in ebay send me the link so i can buy it.
Thanks, Marcelo

Hi, I have a Samsung UA40K5570AULXL TV , unfortunately my son grabbed some cable and TV falled down. Actually when it falled only the right frame was cracked and left one was misaligned but TV screen was working fine and I let it work for 10 days, Then I called a samsung technician to make that frame align, the frame was aligned but he made a hole at the bottom center of the panel and gave his friend's number to my wife and said to consult for repair. His friend is saying nonsense that screen is broken
How come the tv worked for 10 days and it broked after he came, please help the symtom was horizontal lines and vertical lines on left side also a black patch. After a while whole screen gone and no image seen on the display.

Thank you for the video. Samsung 50 inch that had the back light on, the sound was on. It faded to black while viewing. One T-conn board later and boom, it's back. I really didn't want to replace the tv as it was only 2.5 years old.$50 and the reassurance of this video, and I get my tv back. Thanks again Shop Jimmy
