Re: LG 42PC3DVA Plasma no picture.

No luck. I heated it for almost ten minutes, would not come out.

I think I'm going to take the board to a repair shop that has a proper desoldering iron and just pay them a few bucks to remove it.

Heatgun! I didn't even think of that... I'll give that a try.

Re: LG 42PC3DVA Plasma no picture.

Ok last night I spent over an hour trying to desolder the module. I have a solder sucker (spring loaded type) and that barely removed any solder. I ended up using wick, but still cannot get the module to budge.

It looks like I've got 98% of the solder is removed from each pin, but there must still be some there holding the pins in. I tried cutting one row of them off and using the wick some more, but that didn't make a difference.

Any suggestions? I wish I had a desoldering iron or at least knew someone with one....

Thanks capkid! I will definitely check the Vzb voltage and see what that is. Like you said, if that checks out fine, I will just leave the ZSus for now.

I did contact the seller and asked if the IPM is new or used, the response was this:

"It's manufacturer refurbished and fully tested."

So, to me that means it's used. If it works, that doesn't bother me, but as you mentioned the lifespan may be shorter.

That being said, it is heat that causes these to fail from what I understand....

Friend gave me this TV. He said there was sound but no picture. I noticed if you turned on the power, the led would go from red to green for less than five seconds, then turn off and go back to red.

Removed the back cover and discovered one bad fuse on the Y sustain board. New fuse made no difference. I pulled the power connector off the Ysus board and then turned on the power. Now the power stays on with the green led for a long time. Plug the connector back in and it only stays on for a few seconds as before. Tried it several times both ways. So, I take it this board is toast? ...

Hello All!

Have about 25 years experience in the computer/networking industry. Did a bunch of cap replacements over ten years ago when the bad caps thing happened. I'm mostly a car nut on the side, but not afraid to try and fix anything at all. Tractors, snowmobiles, appliances. Now I have an LG Plasma that failed and hopefully I can get it working and install it in my garage. ;-)

Looking forward to participating in the forum, although I'm not sure if I can contribute yet.
