I am working on a LG 60PX950-UA That the center white light blinks twice, and shuts off. I have unhooked the Y-SUS Board and powered on and nothing changed. I then unhooked the Z-SUS Board and powered on and got the same result. Anyone else had this issue with a LG60PX like this?

Check for Vs & Va voltage with both Y- and Z-sus connected.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Tom, I will check those and report back to you later today. Thank you sir!Comment

Re: Lg 60px950-ua
Tom,
The label on the panel shows the voltage should be VA 60v & VS 203v. The power supply is producing VA 58v & VS 199v. Would that cause it to shut down?Comment

Re: Lg 60px950-ua
That is fine. Unplug the TV from the mains power and allow it to discharge for at least five (5) minutes. Then connect the Y-sus and Z-sus again and measure Vs and Va voltages again.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Lg 60px950-ua
Tom, I found your thread advising to unhook the LVDS cable from the control board and installing a jumper wire into the pin holes like this
https://www.badcaps.net/forum/attach...7&d=1376575578
I tried that and the test screen came up! So do I need a control board or a main board? pictures below of the set I am working on. Thanks again for your help!Attached FilesComment

Re: Lg 60px950-ua
Good! You would need a main board.
(I was going to suggest that as a next step
)
There is also a "3D converter" board on this set, in between main & control. However from what I've seen it is usually the main board that fails.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Tom, once again, I have to thank you!
Do have an address where I could mail you some untaxed adult beverages from the MTNs of NC?

I appreciate the offer. I live in the UK and am personally tee-total, so not sure it would work!

Re: Lg 60px950-ua
Hi, I believe I might have a similar issue with my LG 60PX950 tv. I get no picture and sound when I power on. I added the jumper wire and unplugged the LVDS cable on the control board as shown in the image you provided and my screen goes from black to a grayish white - no cycling test patterns. What was the test screen that you saw and did replacing the main board fix your issue?Comment

Hello,
Purchased a broken Samsung UN39EH5003FXZA (Version CD01) to have fun fixing. When I first acquired it, I did not connect any video signals and only plugged it into the wall. The unit booted and showed the “no signal” window and I could navigate all menus and change sources. I unplugged it, connected my over-the-air antenna to the coax, powered it on, got the unit to scan the HDTV channels, and I think then the TV self-shutdown with the melody. When I powered back up (melody), it would show the channel selected on the OSD and after a couple of seconds, it self-shutdown... -
I have this machine. It powers up and gets fan spin, will even shut down when I hold the power button.
U1200 gets very hot under thermal camera, the next hottest region is UB000 and L7030. I'm assuming L7030 is warm due to charging.
Do I have a potential dead CPU? or just a dead U1200? Not sure what to check since everything is powered up. -
Hello Everyone! I have a Yamaha powered speaker DXR15. The problem was the RED LED Fault indicator is steady on when I power the speaker. I did open the module and I don't see any burnt component. I Downloaded the Schematic but I don't know where to start the diagnostic. Any help would be greatly appreciated. I also attached the schematic here... -
Hello everyone.
I need help with my Yamaha MSR400 - Powered PA Speaker that I bought it used recently.
It is power on, and sounding good / working perfectly fine. However after 3 - 5 minutes, the heatsink is starting to get warm, and it smells burning a little bit.
I did tried multiple times on different day, event the speaker is not playing any song (input does not connect to any source, and the volume level is zero), after it turns ON, 5 minutes later, the heatsink is starting to get warm, and it smells burning a little bit. I am afraid keeping it ON longer than 5 minutes... -
Replaced Zsus beginning of year as most transistors were short stopping tv powering up.
Now screen flashes on off continually and ZSUS ticks. Looking like replacement maybe faulty or could something else cause it to shut down.
If I remove both tabs from ZSUS to screen but keep all other connectors to ZSUS on then TV boots properly but screen very dark without ZSUS output, no ticking from ZSUS. So it only shuts down when under load from screen.
If it is ZSUS then how to fault find, I already looked for shorts. No transistors shorted or caps and its...12-13-2017, 01:18 PM
