Monitor cable replacement anyone?

[b1tchm4gn3t]

ok...Im thinkin there is a part on a tv or monitor that can fry your ass. I need to know what its called...and more important...WHERE IS IT? I am goin to order a 15 pin cable for a compaq v75 monitor and I would rather be 'safe than sorry' in knowing what this thing can do if I touch a wrong part. Cable looks easy enough to replace as I have had the case apart tonight to see what all this requires. If anyone has any experience in this matter at all I would appreciate a reply! Thank you.

You will see a rather thick cable going the top of the cathode ray tube.
It is similar to a spark plug wire. It comes from your fly-back transformer.
If you follow that wire down to the circuit board you will see this transformer.
It and all of the components around it are the high voltage part of your monitor. That is where all the zappability lurks.
If you avoid this area, you should be just fine. I do not understand why
you are replacing the entire cable????? Most cable issues, stem from the
connector or very close to it. Why not just replace the end.

HAHAHA...tried that twice and 3 of the wires have 'inner' and 'outer' made into the same wires. (like I said...3 were that way). Maybe I will try that again! Is there any way to dissipate this high volage in safe manner? Just asking that for curiosity. Thank you so much for the reply. Any further suggestions by you would be just wonderful!

A CRT can hold a charge for a few days. If you want to discharge it then use an insulated plastic handle, GROUNDED screw driver. After that everything should be safe.

Let us know the shocking results.

As cheap as monitors are today why not just trash that one and get a new monitor? I've done worse....

use it on what part of the monitor? I really dont want to 'guess' at this LOL

I agree...but I like to try my hand at fixin shit. I like to learn about new things too. And if I go buy a cheap monitor...it wont EVER be as good as this one. I have seen cheap monitors....they suck

Slide the GROUNDED screwdriver under the big rubber cup at the end of the big red wire going to the big CRT. If the rubber cup has a white sealent around it, then don't bother... you'll be OK.

Thank you CHAS

A nice think wire to the ground prong in the wall outlet rapped around the screw driver should work...
My dad used to discharge monitors and he has said that he has done it once where there was a good enough charge to take a little chunk out of the screwdriver from the discharge.

Before you get electrocuted check out this monitor on pricewatch.

AOC 9 KLr - Display - CRT - 19" - 1600 x 1200 / 75 Hz - 0.25 mm

It's like I said, as cheap as monitors are today why bother.

Be careful. ok

Plugging those connectors in should not get you anywhere near the hi-voltage.

And, as for putting on a new end, you need the proper crimper for crimp-ons, if you can even find them, or a steady hand with a soldering pencil to use the soldered type, available at the Shack.

The cable for a monitor I last repaired was 25 bucks, a 15 inch at that, so I soldered on a Radio Shack connector. You gotta make good notation, or have a good reference manual to know which wire goes to which pin.

And, again, if you can't solder, which seems to be a lost art with today's generation, good luck.

Cheers,

George

funny thing is that a USED to have steady hands at soldering... I did go to the shck and bought 2 ends and ruined them both! I did get the proper diagrams though. I think I will try it again, I just need to know why there are 3 wires with 2 wires in it (an inner and an outer wire) if that makes any sense.

rf shielding?

[gmatov]

Grounding, I think. It's a little tricky. Some wires have the outer "wire" soldered to the shell of the connector for a ground. Some, it goes to another pin.

Similar to when Apple devised the mini SCSI connector with a common ground.

Give it another try. If you look at the racks closely at the Shack, you might find a pack of pins without the shell. ( Connector housing )

Cheaper to buy the pins, if you're messing up. They come in a strip and you break them off as you need 'em. Might be easier on you to solder one to the next wire, push it into the connector, rather than soldering the center row of wires. They are damn close together.

Nice to have a lighted clamp on magnifier for this also. It's what I use for this kind of work.

Cheers,

George

So did your monitor bite you??

It doesn't hurt that bad, it's only 40,000 volts discharging through you Remember only touch it with one arm, so the current discharge doesn't go across your heart and make you pass out. It will make your arm sore for about 10 minutes. You can ground the Anode to the braided steel wire that goes diagonal across the CRT, that's the grounding strap. Turn the lights off so you can see the arc as it scorthes your screwdriver tip 8)

[b1tchm4gn3t]

Still havent tried it yet, Im just going to order the right cable and that will mean just plugging it in. I wont be anywhere near the high voltage stuff. Nice of you to be concerned if I got the bite or not.
