Pioneer Elite Pro-510 input problems - Blu-ray Forum

mzo0163 · 05-31-2009, 05:29 AM

the component inputs on this tv seem to have gone bad. One of the component colors keeps going out on the tv so the images are red or green mostly. When I put pressure on the individual cables at the base of the connection the picture is fixed but then will go back shortly after. This only happens with the component inputs and not the others. Ive swapped the cables/DVD player and still the same problem so it has to be the TV. Does anyone know how serious of a problem this might be and how costly it may be to fix? Any info would be great, thanks.

Sounds like you have a bad solder connection on the input board.

Just a guess but you say that you can fix the problem with pressure and then it goes back after a while.

Sounds like you have a bad solder joint in the component video somewhere and when you press it you make a good connection and fix it.

It could be your cables too but it looked like you said you tried different cables plugged into your component video and it didnt change it.

Its probably the big pads that are directly connected to the blue/red/green inputs you plug into. They are larger and take the most abuse due to plugging and unplugging.

Thats just my first guess. That is the simplest fix that fits your problem i guess. Could be something else?

that was my guess too, If that were the case would I just need to re-solder the joints? I dont have any experience with that so I dont know how easy it would be or how much it may cost to have someone come out and do it...

Ok im not greatly familiar with pioneer.

That is a rear projection tv right. I know your in the rear projection forum but i just gotta ask. Not that you dont know what you have but i want to know to best try and give you good advise.

Soldering is not too difficult.
It would consist of taking the cover off the back of the TV set. Finding the board that has the component video connections and re-soldering the pads.

You would need a soldering iron and some solder. I don't know how much it would cost to have someone come out and fix it for you.

If you are handy and think you can you may be able to pull the component input board out and take it somewhere and have them re-solder if for you. It would probably cost less than having them come out.

Usually that input board is a thin card and it plugs into a larger board. Usually you just have to just pull the card out by just using a small screwdriver and unhooking the little tabs. Its really easy.

If your not confident id call a tv repair place and see what they would charge to come out an look at it.

Yes it is a rear projection, thanks for the info. I think ill try to take it apart and see if I can solder it or find a friend that would have more experience. Im just hoping I dont screw somthing up.

Soldering isint too hard.

You will sometimes be able to see a ring on the pad which will indicate a crack. Sometimes they are visible sometimes really hard to see.

Soldering is just like welding. You want to heat up the pad and the leg of the input to the same heat then add solder.

On the bigger pads it takes more heat but its usually harder mess it up. The smaller pads it is possible to get them too hot and lift a pad.

Basically you want to turn the iron on and let it heat up all the way. Like 600 degrees. Then "tin" the tip by adding a little solder to it and the solder will "flow" onto the tip. Then put the tip touching the pad and where the input goes through the pad. The iron will heat it up until the solder begins to flow. You will just have to add a little solder to fix the bad solder joint.

Here is a pic of kinda what you want to do.

Good luck.

Thanks a lot, I appreciate it.

I was able to fix the problem easily by taking off the back of the TV and re-soldering the input board, just some fresh solder on the component joints and everything is fine now. The problem wasn’t with the tv per say but with the excessively tight monster component cables that had to be aggressively taken off whenever necessary which over the span of five or six years cracked the solder joints.
