Re: Samsung UN48J6300AF TV - no power, no standby
When I bought this TV, the only difference I knew of was the TS01 used a Samsung panel. All the other features/specs are identical. You could find the TS01 on the shelf next to the US02 - both sold as model UN48J6300AF.
If you look at the attachment in my previous post it lists the parts for both versions.
Panels: different part numbers
Main board: different part numbers
Power supply: same part numbers
TCon: different part number
See link below for a pic of the 2 main boards...

Re: Samsung UN48J6300AF TV - no power, no standby
Thanks for all the help. Is there any hope of tracking down the exact point of failure on the main board? Maybe it's possible just to replace the bad component?
When I went order the new main board I discovered that this Samsung TV has 2 versions (TS01 and US02) - see attachment below. The TS01 main board in my TV is much less common - only the authorized Samsung Parts website seems to carry it. And the TS01 main board costs 4 times more ($220) than the US02 main board.
What's the likelihood the US02...Last edited by mildew; 11-08-2018, 10:00 PM.Leave a comment:

Re: Samsung UN48J6300AF TV - no power, no standby
I put the power board back into the TV and the results are listed below. I noticed when i leave the ribbon cable going from the power board to the main board unplugged I get backlight, but when the ribbon cable is connected no backlight.
Pressing the power button doesn't seem to doesn't seem to change any of the readings.
1) 8.78v
3) 8.78v
5) 8.78v
7) 8.78v
2) 1.0v
4) .01v
6) .09vLeave a comment:

Re: Samsung UN48J6300AF TV - no power, no standby
I just checked and with board not connected to the TV:
pins 1, 3, 5, 7 all had 12.72V
I guess this indicates the power board isn't completely dead like I originally thought. What should i try next?Leave a comment:

Re: Samsung UN48J6300AF TV - no power, no standby
Thanks for the quick reply.
The power board fuse has continuity. So I need to measure voltage across pins 1 and 9 (see new pic of CNM803 below) and should I be expecting 8V or 13V? The legend makes me think 13V but it shows at the top of the board standby is 8V.
Do I need to reconnect the power board to the TV before testing this?
The strike did take out the cable box connected to the TV, but the DVD player was unharmed. I've also attached a pic of the mainboard....Leave a comment:

Samsung UN48J6300AF TV - no power, no standby
I'm not getting any power and there is no stand by light - it went out after a lightening storm. I figured the power supply board is the first place to start, but I'm not sure how to test for standby. At the very top of the board it shows: STB:8V ON:13V (see 1st pic below), but where exactly do I take those readings? I've already pulled the power board out so when I take the readings is it OK to test it outside of the TV?
I'd also like to check the mainboard but I'm not sure where to start with that one....Last edited by mildew; 11-05-2018, 10:24 AM. -
Re: Finding replacements for Su'scon caps
Any concern about the ripple current on the Nichicon 33uF and .22uF perhaps not being up to spec? I'm not sure if that's the case since like I mentioned before I can find the full specs on those 2 Su'scons.Leave a comment:

Finding replacements for Su'scon caps
This is for an lcd monitor that won't power on. At least 3 Su'scon caps have gone bad and I plan on replacing them all.
Su'scon 1000uF, 16V, 10x20mm, SG Series (R.C.=1820)
Su'scon 470uF, 35V, 10x20mm, SG Series (R.C.=1820)
Su'scon 33uF, 50V, 6x11mm, SG Series (R.C.= ?)
Su'scon .22uF, 50V, 5x11mm, SK Series (R.C.=11 ?)
This is what I planned on replacing the Su'scons with:
1000uF -> Nichicon UDH Series - UHD1C102MPD (R.C.=1820)
470uF -> Nichicon UHD Series - UHD1V471MPD (R.C.=1820)
33uF -> Nichicon UPW Series - UPW1H330MED... -
