Looking for a ground connection

Can't find anything that answers my question. I tried.

I'm about to pull apart my first TV. I can't find a ground on this particular model. Using the screwdriver-and-wire "system," can I use a heatsink for a ground to check the high voltage system?



I've never had a problem finding a ground on a monitor.

Eventually, I usually figure things out one way or another. I must have been using the wrong search words because all my google searches kept taking me to the "proper way" to discharge the CRT. I wanted to use the screwdriver method.

The TV is indoors. I'm not taking it outside to my car to find a ground. It's heavy. It's also cold outside. Ain't happening.

But finally, I dumbed down my search and found the info I needed. So now I know how to find a ground in a TV when I don't see anything grounded and no ground symbols on the circuit board.

Thanks anyway.

Now I have to figure out how to get the yoke off. No screws & clamps holding it down. It's glued to the CRT. Never saw any videos or read anything about a TV like this one.

billygoat, if you have a grounded power receptacle you can make up a clip to ground to it, or throw a ground stake out the window into the ground and run a wire into your work area to clamp onto. If your in a garage with the power receptacles run in conduit, you can even run a ground clamp up and clamp onto the conduit. It'll feed out to the earth ground. I mentioned in an older thread that you can get a motorola plug and jack and mount the jack in a blank wall cover for a recept. Connect your ground wire to the motorola plug, and feed a ground wire from a ground rod to the motorloa jack in the wall. When you need a ground, just plug in and clamp the other end to the screwdriver.
Male plug,,

Female wall jack.,just mount into a plastic wall cover for a recept.

Probably held down by the plastic 3 finger diddies that are some times screwed onto the neck. If it's glued down just gently start a screwdriver under the edge of the yoke and gently pry up. The glue should release.

Electrical ground that you should be looking for in a tv can be the the copper part of the brown board. Its a common ground you are looking for. If you heard a "snap" when you make contact then you got it. If I were standing next to you it would be easy for both of us.

Next the search on this forum for 3 letter or less words does not work. So if you look for vcr, tv, crt, it does not work. I have had some luck using google search with "scrapmetalforum" inserted in the end of the search bar.

Our member Hoss has taken apart hundreds perhaps thousands so if I had a crt/tv question I would pm him.

I waited to answer this in hopes someone with more experince would but I think the others may have missed the mark or perhaps I did. Mike.
