yeah i could use pliers but these caps and the connections are so small il risk tearing off the pad,solder or both. Thats why with friction i hope to leave part of the leg for me to solder on. But sometimes the cap fluid corrodes it so bad the cap can just come off with a touch taking with it the precious solder leaving  bare pads.
If this happens to you guys don't worry. If theres just a little bit of solder on the pad you can run a drop of solder from your iron tip to add more. if theres absolutely no solder getting solder to hold wont be a problem. The best way is to put solder paste on your cap leg and pad then a drop of solder from your iron. The solder wont stay on the pad without the metal from the cap leg to react with it. Its like witchery but will hold

I want to know if I can solder onto one of the legs of the component circled in blue. Right now I'm trying to solder onto the trace located on the orange circle but it's a no go.

Again see the diagram I posted or pm me if you want me to repair

That didn't really answer my question though. Can I solder onto one of the legs of the component circled in blue, and if so, which one?

What makes you think you should solder to that chip?

I'm confused, ApolloBoy. Below is the photo that has the correct solder point. I'm assuming your photo is Duo_R's blown up. On the previous page we have outlined the areas that you can solder to to correct the broken traces. Duo's diagram is about as concise as you can get.

Exactly. The answer is no, you should not solder to that chip.

Apollo do you have experience with soldering electronics? If not send to Chops (he already offered to you for free) or I can take a stab at it. I think I already spent way more time sending diagrams, etc that it would have taken me to have just done it already. lol

This is just weird, because I've tried every area you and Duo_R have shown, and I'm still not getting any video.

I've got plenty of experience with soldering. I've done mods and repairs for people and I've replaced the caps in two Game Gears and another TE, among a few other things. I can do this, it's just that this TE is being frustrating to work on right now.

I think we all run into one piece of hardware that kicks our butt.  I had a turbo CD do that to me... its now been hacked up to save a few other turbo CDs

Sorry if you already stated this but has video ever worked on this unit since you had it? Why were u replacing this cap to begin with?

I agree. I have a duo that is in chop5's care even though I have replaced every cap, the laser, the motor, and the headphone port.

I'm actually fixing this for a friend of mine, who bought it on the cheap and found that it didn't work. When I opened it up, I found that most of the caps on the unit had leaked and needed to be replaced. I've succeeded in replacing all of the caps and getting every part of the system working except for that one video cap. My friend actually tried to replace a few of the caps, including the video cap. He didn't do that great of a job replacing them (and admitted this to me beforehand), hence why it still wasn't working when I received it, and hence why both the solder pads for the cap got lifted when I tried to redo it.

Have u swapped screens with another unit to confirm the screen isn't bad?

I have a TE of my own, so I suppose I could give it a try. I'll do the swap tomorrow and see how it goes.
