Samsung Syncmaster T220 - bad caps?

Re: Samsung Syncmaster T220 - bad caps?

I cannot edit my post those old posts. manage attachments it not working.

if you quote my post you can see the links I posted and go directly to pictures.

I really hope I didn't break that plug for no reason now.

Lumberjack777 did you look at my pictures? What is your advice?

Also I need to fix this wire or I won't be able to to turn it on.

There are still pieces of the wire in the plastic.

The pins stay in place by the fingers, you have to press the fingers down and slide out the terminals. Can we see the side views of the connector?

Re: Samsung Syncmaster T220 - bad caps?

budm can get you fixed up. Don't worry, that's just a wiring connection. The most important thing is that you don't lose track of the order of the wires in the connector. 1 black and 4 white. They could get mixed up. Number them if you need to with a piece of tape. I'm going to be awayfor a few days. Make sure to check those voltage regulators on the main board like retiredcaps showed in his guide. No worries man

Howdy marlo

I'm keeping an eye on your progress, I am interesting in seeing this get fixed!

The connector looks like it got pretty mangled, does it feel like it would stay in place when getting the wires reattached? I'm thinking off all they ways that can be fixed and I'm interested in what others have to say as nothing I can think of will be very classy.

If you look at your connector, there are samll opening for the finger of the terminal to lock in place, you will have to use small pin to press into the opening and push out the terminal at the same time.
See example of the typical terminal.

I just borrowed a multimeter today. So I should test the voltage regulator.

Do I need the board plugged in the wall the whole time or just for a minute?

OK, in your case since you have 2 identical monitors, you can isolate where the problem exists fairly easily.

First of all, we need you to acknowledge advice already given you. Did you see what budm posted about how to release those pins to re-attach the wires? You are going to need to re-attach them to test the voltage regulators; because there needs to be power running to the main board. Everything will be hooked up and a vga source coming in from a computer. Read the guide by RetiredCaps please.

Your problem sounds like it is coming from the main board; so what you can do FIRST to be sure this is the problem area, is to take the main board from the faulty monitor. And install it into the good monitor. If you see the same fuzziness then you will know the problem lies in the main board.

But, I'm only giving you this advice if you are sure you can disassemble the good one without mucking up the wires, or damaging it in any way.

Then you could know for sure it's the main board. You also need to work on re-attaching those wires to the connector. Then we could test the voltage regulators if it turns out that the main board is proven to be faulty.

I don't feel comfortable taking apart my only working monitor. I have no money if anything breaks. I can spend a few bucks here to replace capacitors but not $200 for a new monitor.

Can I not test the voltage regulators without redoing this wires?

Those wires are only for turning the monitor on.

Yes, and the monitor needs to be on to test the voltage regulators.
Here's the guide to read. https://www.badcaps.net/forum/showthread.php?t=22231

I'd say your first step is to re-attach the wires. Power up the monitor. And get back to us.

Re: Samsung Syncmaster T220 - bad caps?

well that's not good I didn't think the screen had to be on to test them. Just the pcb.
can I just leave the broken piece of wire inside and solder it back together?

It has some plastic coating around it and I cannot pull it out.

Re: Samsung Syncmaster T220 - bad caps?

can't seem to edit posts on this forum.

here are 2 pictures.

the wire is really stuck in the little metal part I can't push it out. I don't want to break the metal thing then I am really screwed.

am I able to use this solder shown in the other picture and just solder the wires back together? It should be able to melt through the plastic coating I would think.

Re: Samsung Syncmaster T220 - bad caps?

anyone? Just trying to get these out is hard and the wires are so small. Can I solder it and the plastic insulation around it? my hands shake really bad trying to do this.

Re: Samsung Syncmaster T220 - bad caps?

I have no clue what I am doing. The only thing I have been successful at is burning my finger with the solder iron.

The wires are so tiny I cannot twist them together.

the broken wire is lodged in this metal piece so there is not even enough to twist.

The metal terminals are crimped. You have to stick a pin in the end and pry and uncrimp them a little so you can slide out the old broken wire piece, and slide in a new wire and crimp it back up tight. Then slide them back into the connector in the proper order.

Re: Samsung Syncmaster T220 - bad caps?

is this some special pin? I can get it open but it still will not come out.

The top one open by pushing the bottom does not open.

Also how am I going to test the voltage regulators with the monitor on? The PCB faces down at the screen. So the voltage regulars are not accessible when it's all put back together.

I also burnt the insulation off the wires because using a knife was impossible.

Where do I get this pin?

[mariushm]

Re: Samsung Syncmaster T220 - bad caps?

Oh man... it's no special pin.

Get a very small flat head screwdriver and use it like a crowbar or twist the screwdriver to widen the place where the wire is crimped onto that connector.
In the past, I've even used nailclippers

see the pictures attached, made them specially for you

Re: Samsung Syncmaster T220 - bad caps?

Thanks but did you see my picture?

The plastic insulation is removed. The first crimp is apart, but there is wire going under another one or looks like it. that one doesn't seem to be removed.

so what are my options?

[budm]

Re: Samsung Syncmaster T220 - bad caps?

I what do in that case if I do not have the new terminal is to carefully solder the wire to the front crimp section which is hard to spread back out and then crimp the back section ofthe terminal to hold the wire insulation.
