Did I ruin this board?

[pipestretcher]

Hello,
I'm currently dealing with exact same TV, components, and issues as the one in the thread titled, "Samsung 50" Plasma, No Picture or sound". I'm OBVIOUSLY an amateur when it comes to de-soldering components. In attempting to remove the MOSFETS from this board I also managed to remove the small copper ring at a couple of the solder points. Take a look at the pictures and tell me if I have ruined the board or can it still be saved.

Thanks in advance, any input is greatly appreciated.

Can we see the bottom side of Q809? It looks to be salvageable.

Sorry Tom, and thanks for the reply. I thought I had all of them pictured. As soon as I get home this evening I'll shoot a new picture.

Two questions in the meantime...Are there any other pictures I can provide? From the looks of things, and in your professional opinion, should I be attempting this at all or should I just stick to pipefitting?!

Well, I think the damage is repairable with some skill. I'd recommend you improve your desoldering skills a little, but it doesn't look too bad.

Here is front and back of all 4. The back of 809 is visible here.

Your pic attachment skills are not too great either.

Nevermind.

Looks like you ripped some pads clean off... You really ought to get a higher-powered iron. You know, 60W models go as low as $6 shipped.

Use a new Xacto knive blade with small tip to scrape the green paint off the remaining copper traces just enough to solder the part leads on. Use some tinned bare wire to make connections with if needed. Hopefully that is only a two-sided pcb and does not have hidden traces inside.

Maybe its worth $100.00 to save myself all this trouble.

Sparkey, I finally got a 60w iron and I want to attempt to fix this problem. How will I know if I'm actually able to do it or not.

Although it doesn't sound like it, I'm not a total dolt, I do have the ability to pull it off but this is a new area for me. If I can learn how to work on these things properly, I'll enjoy the challenge of trying another one.

You need the 60w iron more for removal than soldering. If I were you, I'd go to youtube and watch a couple tutorials.
