LG 42PC3D-UE horrible picture w/ good sound

[Rolling]

Mine is a October of 2006 42 plasma LG, by reading here it looks like the Zsus board has malfunctioned. I verified there is an open fuse on the Zsus board, all the rest of the fuses ohmed ok.
question1: Is there a specific orientation to how the fuses are put in the holders? My automotive history tells me no, I was very specific when I removed each of them, I know there are 4 that are the same and 1 thats different, I made a note on which one goes where. I didnt however look to see if there was a specific way they were put in. Kinda like a +/- maybe??
question2: Where can I find the correct part number for the Zsus board for my TV? Do I need to search for a repair manual and get the numbers from there? It looks fairly easy to replace, I dont want to have to spend money on a book for something I can figure out on my own.
Thanks in advance!!

iirc thats the one you need.
i replace a ton of the originals.you will also need a 4a ceramic fuse.

Thanks for the quick answer! However...I think disassembling the Zsus board is going to be a little out of my skill range. I'm not the greatest with a soldering iron (will burn house down)

I am the greatest TV repair guy ever!!!! One new (refurbed) Zsus board and the old LG is workin great!!




Ok....so I dont have a clue what I actually did, but the new board seems to have fixed the picture issues I had. Installation was very simple, just be gentle unplugging the connectors and make sure everything was seated completely and I guess I did something right cause its working again. Honestly, I think these things are held together by magic and you guys are just freaking wizards and cast spells to make the lights flicker...

On to the next problem, now my xbox and PS3 are showing "Invalid Input" when hooked up. They both used to work just fine on this TV, but now they aren't talking. I have hooked up the cable box to both HDMI and Component video and all the hookups appear to work, is there a master reset for the TV brain so I can get all the inputs to configure correctly?

I've never seen that error. Let's see if I have the correct information. You have a cable box, an Xbox360, and a PS3. The cable box works fine on both HDMI and Component inputs. Is that a correct summary?

If I recall correctly, the TV will accept 720i, 720p, and 1080i inputs, but cannot handle 1080p. So the question is, what were the Xbox and PS3 hooked to while the TV was being repaired?

Re: LG 42PC3D-UE horrible picture w/ good sound

Ahhh....you are correct! I had the TV's switched, the LG was in the bedroom hooked up to the blueray player that was switched to 1080i, and the Hitachi was in the livingroom hooked up to everything set at 1080p.
Guess I get my Hitachi back after all!!
