Re: LG Plasma 60pk950-UA no picture or sound
Reseated both ends of LVDS. As far as a power sure I don't know. A while back the HDMI port on my DirecTV DVR burnt out and they assumed it was a power surge.Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
Ok, I did this again and my screen starts changing colors. So I assume the main board is bad too?...Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
Got my buffer board today and intalled it. -Vy,Vsc voltages good now. Still no picture. Any ideas?Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
Ok, its the lower buffer. With it unhooked the voltages are good and the top half of the screen has a faint white glow. Thanks a million for your help. Also is there a way to donate to the forum or to you for the great service provided?...Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
OK, something strange going on. I unplugged the white wire going between the buffers. Uhooked p104 and tested voltage and it was good. Hooked p104 and unhooked p105, tested and voltage was good. Hooked everything back up and voltage was good? Also I guess I need to know what voltage you want checked. Also what should I see for voltage on Vsc and -Vy?Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
When you say isolate the buffers, do you mean remove the p106,p206 connector that jumps from one board to the other?...Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
Sorry, kinda jumped the gun on that one. If I unplug p104,p105 the voltages are good. ShopJimmy has the Y-SUS and buffers in stock. Would you recommend replacing the buffers too?...Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
If I unplug p113,p114 and take the y-sus out of the equation my voltages on f801,501,301 are good. When the Y-SUS is connected my incoming voltage to the power supply drops to 60v....Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
-Vy jumps between 10v-40v
Vsc jumps between 10v-30v...Leave a comment:

Re: LG Plasma 60pk950-UA no picture or sound
I was doing some more research on here and I found a block diagram for the 60pk750 with the 60r1 panel. Since it has all the same boards and panel as mine except for the main board am I to assume the voltages will be the same? If so I took some measurements on the power supply. f801,f501, and f301 only read half of what they should according to the diagram.
VS=201.6
VA=59.6V
M5V=5.15V
17V=17.17V
STBY=5.15V
F801
stby 0v
run 174.7v
F501...Leave a comment:

This is the only board I am having trouble finding. Everyone is out of stock.
Is there someone on here that can repair this board?...Leave a comment:

Yes. It flashes once, then a real quick flash. A few second pause, then repeats....Leave a comment:

LG Plasma 60pk950-UA no picture or sound
I am looking for some help troubleshooting an LG 60pk950-UA plasma television. When I took the back cover off I also found this number PDP60R10000. TV powers up but no picture or sound. We didn't use the tv for almost a year and when I went to turn it on yesterday it powered on but no sound or picture. In the past it acted up a couple times(had sound and no picture or picture and no sound, cant remember which one it was) I assumed it was the LG wireless media box. If you power cycled the tv then it would work. Now I have no sound or picture. Any help would be greatly appreciated. I have attached... -

Hello, I am new to the site. I am an electrician but I deal mostly with motor controls. Joined to try to get some info on how to fix my tv. Did a lot of reading and seems like a great site but I need to ask some questions so here I go.Leave a comment:
