CRT problems Macintosh plus!

[The MAC MANIAC!]

Can i disconnect the logic board without discharging the CRT? Its been a few hours without plugging it in!

It depends upon your skill and comfort level.  It also depends if you mean analog board or logic board.  I would feel quite confident in my skills and the risk level for replacing the logic board, but not the analog board. 

PS: It's not hard to discharge the CRT

I have no wires or clips to attach to the screw driver!

The logic board i am not messing with that analog board  i would rather take it to some guy that knows what the risk are and what to do!

It was once easy to solve that by going to your local Radio Shack and picking up alligator clips; however, it is not so easy now.  As such, I would consider ordering cheap online or if you are on a tight time table other stores should have something.  If you just want to swap the main board, know the risks are lower for that than the analog board.

You may find this video helpful for evaluating the risks - it really is an easy job, just have to be careful

The only hard part is not pulling too hard on the power cable and hitting the yolk/tube area

Will take notes. Also what would be best to disconnect the cable no hands on?

I have taken apart a 90s PC and i think it would be easy to take it out with something besides my hands!

Thx i will go try my best right now its on the carpet next to me...

Well, you need to use your hands to click the disconnect and also pull up, but you must be gentle, avoid pulling to hard and hitting the CRT.

Ok you think its safe without it being discharged this is a first for me? I trust you tho!

Im still scared at this point but you give me a lot of confidence! 

 

[The MAC MANIAC!]

How do you click the disconnected ?

 

[maceffects]

These Macs were designed to reduce their voltage when turned off, but you never know. As long as you pull gently and evenly you should be ok.

Thanks i have got the hang of it and now i am able to confirm that the Logic board is the cause of the problems the machines having! Thanks you were a big help!
