This plasma tv when plugged in only gets the red light with no response from the power buttons. Im seeing some rusted resistors on the power supply. Just wondering if there are common components for this model that fail.

Re: Samsung SP-R4212 Plasma Red Light
You appear to have 3 red circular fuses on the power board. I cannot read the designated numbers. Have you check they are not open circuited?Attached FilesLast edited by dick_barton; 01-13-2019, 11:34 AM.Willing to help but I'm no expert. -

Re: Samsung SP-R4212 Plasma Red Light
Anyway, i just re-seated the cables coming from the power supply to all of the other boards and it started working again. This made me think i had a cold solder joint but i hauled it back out and checked the soldered connections and didn't notice anything out of the ordinary.Comment

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... -
The TV is a 2013 Samsung plasma, model # PN60F5300AFXZA.
Snagged it up in non-working condition a couple years ago. Previous owner said that sometimes he could get it to come on after repeated tries but other than that he couldn't get it to turn on.
Personally I haven't been able to get it to turn on at all. The standby light comes on solid when plugged in, but pressing the power button results in the standby light flashing once every 4 or so seconds. No "click" noises, no light from the panel at all. Just the flashing standby light.

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...
