Changed out that cap anyway and still no joy.

Well I ended up ordering a power supply board and that fixed it. Sure wish I could have fixed this one.Comment

At least you got it working, it may help to take those voltage readings to see which one is not correct.Never stop learning

Re: Samsung LN32A450C1D Red light
Ok I have the same problem, I have 5 volts Stand by only, short pin 3 to pin 1 and no result,
Solution: Replace resisitors RM815, RM825, diode DM810, ICM801 and cap CM810.Attached FilesLast edited by andariego; 09-30-2015, 12:31 PM.Comment

Good to know. Have any part numbers and where to purchase them?Comment

Re: Samsung LN32A450C1D Red light
To be honest. The service manual says the values, but what I did, was desoldering a resistance with the same value (1002) in good condition and measures the value(10 khoms), the same thing with the diode and the IC801 take another chassis that was in my workshop as the capacitor.

TV: Samsung QLED QE65Q7FNAT
PSU: BN4400940A
MB: BN94-12832K
I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r... -
Hello,
I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.
I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere.... -
Hello everyone,
I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
What I already found is that the 12.8V are not an the connector to the main board connector to the power... -
Hello everyone!
Tonight I picked up a Samsung UN65NU6900FXZA with a curious issue.
Symptoms:
1) Plug TV in to AC outlet, stand-by light illuminates briefly and goes out.
2) TV does not appear to turn on
3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
4) "Power on" terminal on Power Supply has 3.26v
5) "A13V" terminals have 12.9v
6) Stand-by test jumper on Power Supply has 12.9V
7) Optical audio jack on Main Board illuminates
8) With stand-by...
