I have a Samsung 23" LCD TV, model number LNS2352W. When I press the power button, nothing happens and the standby light stays on. If I press it again, sometimes the standby light will go off. I opened the back and found that one of the capacitors on the power supply board was bulging and burnt. I found a replacement board online and put it in, but still have the same results. Does anyone know if there is a main fuse on the model TV that can be replaced? Or what other component could be the cause of no power?

Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On... -
Hey Everyone,
So I've got this Samsung and the reported issue is that when powered on the backlight comes on, but no picture, no sound, it will flicker, the standby light will flash red twice and repeat the whole process...each loop lasts about 15 seconds.
I've googled the issue and understand it is likely a panel/driver board issue, but was hoping the "tape method" could be successful. Before I did that though, I disconnected the left LVDS cable and powered the TV on. This time I got sound, no picture and the two blink standby light stopped. Did the same...03-27-2023, 07:01 PM -

I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
