LG 50pv400 Plasma Display issue

Re: LG 50pv400 Plasma Display issue

More than likely yes. LG has been using the same panels in their 50" 1080p TVs for a while (what this means is you could take the panel out of a 2012 Smart LG 50" 1080p and stick it in a 2012 Dumb LG 50" 1080p and it should work... all other factors being the same)

I hope these two models are identical except the numbers. As I understand it the 400 model is a Costco number as the 450 is everyone else. I haven't replaced a screen before so I'm cautiously optimistic. I will be searching for how-to's for sure. Thus far this forum has been a great spot to learn. Thanks for your reply tom66!

It will probably be easier to repair the fault with whichever is faulty... rather than swap the screens over.

Re: LG 50pv400 Plasma Display issue

That is a great point but I've not been successful at finding that fault yet. I figure the screen replacement is a good learning experience too. (Hopefully)

It will be easier to swap the boards over. Try to locate the fault, anyway. Using a multimeter, you can find most plasma TV faults.

Re: LG 50pv400 Plasma Display issue

I swapped out 450 model boards (both buffers, y main, power supply, and x main) and put into 400 model. No change. Red standby lights but no change with remote or power button.

Try swapping main A/V board

Re: LG 50pv400 Plasma Display issue

I will try that. I also noticed there is a slight diff in VS label. 450 label states 201v; 400 label states 203v. Not sure it makes a diff since I'm swapping them out.

SMUDDGE- I would like to here the outcome of your TV problem if any... I have a situation similar to yours with a 60PV450.

Re: LG 50pv400 Plasma Display issue

Bob I would suggest making a new thread, the 50 and 60 PV series are completely different in the way they run.

I started one a couple days ago. Just waiting on some input.

Thanks,

Re: LG 50pv400 Plasma Display issue

Im having issues with this same panel, although i have fully functional screen, just with large scale sparklies. Whole screen is green. Followed tom66 guide, checked all voltages and adjusted. But wanted to continue with timing adjustments but found none of those? Any help would be appreciated as I am new to this
