Re: LG 60PZ750-UG Powers Off
Thanks Tom, I will have to work that out tomorrow, I will let you know. And yes I agree now having gone in feet first with this think, I have ruled out the YSUS contrary to my last post.....
What role does the ZSUS play in this puzzle?

Re: LG 60PZ750-UG Powers Off
not to rain on anyone's parade, but after going through the schematic, this is beginning to look more like a YSUS issue. .
If any one is familiar with an adjustment, replacement or other please chime in. I will update as I figure out more.
Also I located a Service manual for this model with very nice schematics. PDF format should anyone need it.
Thanks

Re: LG 60PZ750-UG Powers Off
Alright new (used) power supply, brand new through Sears main board.... TV still shuts down after warming up. Any Idea where to go next? about 300.00 in at this point still cheaper than a new equivalent.
Thanks for help in advanceLeave a comment:

Thank you,
On the firmware I have the latest installed, I thought I could just reinstall from a USB drive, but it tells me no update needed. Can I force the reinstall?

Re: LG 60PZ750-UG Powers Off
Thanks Alastair E, That is what I had been thinking but not sure if the path has another check. Can I force an EEPROM load? I can pull the board and put it under a scope at work looking for cold solder, if it is a bga issue I will just browse the web for a replacement board...
Hoping there is another step/issue from Hamie though, I am about ease and "lets try this" hahahah
Thanks for the helpLeave a comment:

Re: LG 60PZ750-UG Powers Off
30+ minutes without shutting down. I will let it continue. If this turns out to be on the mainboard, is it a simple component R&R?Leave a comment:

LG 60PZ750-UG Powers Off
Hello everyone,
I am stumped, this television started turning itself off after about 20 minutes. I suspect something is overheating though I can't seem to find where. I can turn it back on but then it will shut down again. The caps appear normal no blistering or leakage. I suspect that the issue I am having maybe on the y or z sus board but have no idea what to check or measure. There are some pots on each board y/z but i haven't messed with them.
Anyone that may be able to help I appreciate it it greatly,
Thanks in advance -
