Re: LG 42PX3RVA no picture
Sound Tom, nice one for your input!
I'll try that tomorrow. I may check over the faulty Y-Sus board for those voltages to make sure they are there. Is there any other component on the y-sus that I may be able to test and get it back working?...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: LG 42PX3RVA no picture
Got another tv today to look over and it's the same model as this one I have. I changed over the Y-Sus boards and my one is now working again. So know I know it is the Y-Sus. I have checked over for shorts on the module and found none. So what else can I look for to the board? It doesn't shut off the tv, and the sound is present.
Now, with the good Y-Sus installed back into the TV that I got today, I have a bad picture, lots of ghosting and speckels on the whole screen, What would be the solution to rectify this kind...

[QUOTE=tom66;277158]OK, check for shorts on Y-sustain. From either end of fuse to ground / chassis.
Checked that, no shorts.Re: LG 42PX3RVA no picture

LG 42PX3RVA no picture
Hello, I have a fault in the above tv, when i stripped it down i seen that the y-sus had a blown fuse which led me to believe that the module was also shot too. I have replaced the module and the fuse but still no picture, I have measured the AC detect and it is 4.41 stand by and 4.42 while on. All other voltages are correct coming from the PSU.
Any Ideas????
here is a pic of the damage on the module

Samsung 40" lcd vertical blue line
Hello, I have picked up a Samsung LE40A456C2DXXU which has sometimes a blue line on the right hand side of the set (photo) it comes and goes and sometimes it fills with green like with speaker interference? The sound is ok on the tv if any thing it may be a little on the low side. I have disconnected the T-con and re seated the ribbon cables and it is still there.
Any help would be great, thanks.

Re: Hybrid failure already? LG42PC1D
Got it working this morning, I have a spare ysus and found 65 if cap with the small resistor below it, put it on as a replacement and she's firing on all four now. However I am taking Tom's advice and going to put on the two caps to the 15v pins.

Re: Hybrid failure already? LG42PC1D
I wish I knew what that means! So do I need to replace that part? And if so how do I know with what to replace it with?
