Re: Vizio M55-C2 Mainboard Issues

you might want to post a picture of the back to show how things are connected. Of course, you might want to check what the inductor was connected to in the cabling, if it is and then follow that to...

Re: LG 60PX950N - no HDMI - partly repaired

you can get into the service mode by "creating a special remote" using a computer file and "playing" the file and having an "adapter" to basically "pulse" out the "audio". There are some posts here...

Re: whole new repair / learning world... plasma! Yikes!

yep, that's all my displays are setup. Based on a quick read of the internet, it appears that panasonic changed the "black level compensation design" in 2011 and beyond to not do any "voltage...

Re: whole new repair / learning world... plasma! Yikes!

the sets got 20825 hours on it... so it ain't "unused". Hopefully, the black level "clock" / adjustment hasn't been...

Re: Vizio M50-C1 will not power on

Power supplies voltages will "drift" higher when not under load. measure the resistance on the pin of the cable when it is disconnected from the board to see what the power supply is driving.

Re: whole new repair / learning world... plasma! Yikes!

So the set is now working. The picture is so so as the "mosquito noise" seems very "heavy" compared to my 50 in samsung plasma that is of the same vintage (ie. 2010/2011). Not sure whether that...

Re: whole new repair / learning world... plasma! Yikes!

Did the "short SC50 connector" test with the new board installed. Set (LED) stays on with no flashing. I guess that means the old board still has an issue as suggested herein. I haven't tried...

Re: whole new repair / learning world... plasma! Yikes!

The parts list for the set doesn't show / list any parts for the "missing smd caps" (ie. the ones not on the AF baord)... not sure why that would be yet they are "stamped" on the board so the design...

Re: Vizio M50-C1 will not power on

There is a fuse somewhere on the tcon. (FXXX or something).

Further, the 12v is coming out of the PS. It is sent to the main to be switched to the TCON as required.

As suggested, you don't...

Re: board versioning: tnpa5351...

Re: whole new repair / learning world... plasma! Yikes!

the resistance checks out at 47k (47.1k).

Anyway, I thought I would "throw in the towel" and get a replacement board (supposedly tested). Well, the "towel" might be over my head... :-)

Re: LG LED TV 65UH5500 No picture

before you go too far too fast.... try disconnecting, one at time, the tcon to panel cables and see what happens on power up. Go from there.

Re: Vizio M50-C1 will not power on

It would be nice if schematics were available but you can still do a lot without them.
Your picture obviously shows that the 12v supply is switched by the main board to get sent to the tcon... as...

Re: Vizio M50-C1 will not power on

Re: whole new repair / learning world... plasma! Yikes!

Thanks for the guidance on this as I know little about scope specs other than "features" and "bandwidth". This is a hobby for my "fixed income" self so it is unlikely that the budget (or the...

Re: Samsung UN55FS9000 Half-Screen Dark/Ghosting Issue

As I think about it, maybe not. My reasoning is... basically they are working the same way as they would normally... I think it was referred to as a "push pull" design. In terms of circuit, a...

Re: Samsung UN55FS9000 Half-Screen Dark/Ghosting Issue

Re: Sharp LC46D64U Power and OPC Flash

oops... I misread the number of flashes you posted.
It would appear to be a "det_10v" failure.

but... can you provide a history of the set?

Re: Samsung UN55FS9000 Half-Screen Dark/Ghosting Issue

well... you have to "lose" something by removing something... just the "law of the universe"... :-) The "save" is not "perfect" so if you have "golden eyes", you will be disappointed.... maybe...
