Re: Samsung PN50C540G3FFXZC snowy picture
I checked all the voltages and they were good.
Can someone tell me what the YSUS and XSUS boards do? Could one of these boards cause this issue?
Sorry I don't have pics. Been busy with school and fighting a nasty flu so hope someone can give me an idea.

Never seen this before so posting again. I get this even when I hit the menu button, which is on the bottom picture. Is it tcon, main or panel.

Insignia IS-HDPLTV42 with screen issue
Insignia plasma TV with a strange screen issue. The picture is very small and distorted. Is this a panel/main board or tcon issue.
sorry I didnt take the tv apart to do inside pics. I am very busy and if it is a panel issue no sense wasting my time. Thanks in advance for any help. This is my first Insignia TV.

Samsung PN43D440A5D Plasma will not power up.
The set comes on with the samsung power on music, but the screen is black and no video or picture. My VA/VS voltages both drop right away and the led on the logic flashes slowly, indicating an issue. I get my DC voltages on the power supply, just VA/VS drop after power on.
My VS-ON comes up at 5v at power up then quickly drops back to 0V, and the VA/VS voltages disappear. I know the VS-ON comes from the main board, so is this a possible main board issue. Its not the p/s as I replaced it with one in my shop.
See pics below.

Re: LED TV Driver circuit
So your sure the panel12V comes from the main board. I did continuity checks on main board and only found the 12v at the one pin of the buck converter. The 12V goes to the T-Con, could a TCON problem on the 12V line kill the 12V.Last edited by tech2014; 09-16-2016, 05:06 PM.Leave a comment:

Re: Isolation Transformer
we use 120VAC here.Leave a comment:

Re: LED TV Driver circuit
umm, yeah I do know. Found missing voltage on the main board. Found a buck converter IC with no output voltage. I replaced it and no joy....Leave a comment:

Re: Isolation Transformer
Fuck sakes wasted over $120 on this useless piece of shit, just a big fucking paperweight. I may try and sell it on ebay to recoup....Leave a comment:

Re: Isolation Transformer
I did a resistance check and there is no continuity between the input and output so it is indeed isolated. Problem is I am only getting 60VAC since it is a step down. Is there a way to modify or some way i can still get it to output 120VAC.Leave a comment:

Re: Isolation Transformer
The eBay seller lied in his listing as it says its an isolation transformer. Opened a return request since its useless to me....Leave a comment:

Re: Isolation Transformer
Yes. It is big and very heavy. The listing link is below.

Re: Isolation Transformer
ok I got my isolation transformer. I connected the transformer mains power into the wall outlet, and connected my SMPS I am testing, to the output cable of the isolation transformer. For some reason I am only getting about 45Volts AC out of the isolation transformer. Is there something wrong with it? I got it on eBay.Leave a comment:

Re: LED TV Driver circuit
I tested the voltages on the main board and I am missing the PNL12V TP4000/TP4001 12V. I get 0.017V at SRV-12V on the main board. I did the flashlight test and saw no video.Last edited by tech2014; 09-09-2016, 06:26 PM.Leave a comment:

Re: LED TV Driver circuit
So the BL_ON command does comes from the main board?Last edited by tech2014; 09-09-2016, 06:16 PM.Leave a comment:
