BIG Trev Posted September 15, 2018 Share Posted September 15, 2018 (edited) I stripped my //c monitor yesterday and started the process of fully restoring it. When tested it blew the three Rifa caps on the small power board. I got it dismantled and looked at the crud on the chassis I thought a full recap would be a good idea. I removed the chassis and all of the electrolytic caps then gave the board a clean in isopropyl alcohol. The composite connector needed a clean on the wire wheel as did a couple of the metal parts to remove rust. The case was next and was washed in soapy water and hard to remove marks were hit with a magic eraser. The next step will be a dose of retrobrite. One of the hinge components was broken but luckily all the bits were there and a liberal application of super glue fixed that. Next on the list will be to finish the recap when parts arrive and retrobrite the case and lastly I'll repaint the base or get it powdercoated. I'll post more pics as it goes back together.

Limorange Posted September 15, 2018 Share Posted September 15, 2018 Wow, a lot of those caps are wrecked, no wonder it had a shit fit when you turned it on. Look forward to the final result. Link to comment Share on other sites More sharing options...
BIG Trev Posted September 15, 2018 Author Share Posted September 15, 2018 (edited) Yeah they really look bad. Luckily the board wasn't damaged. Sent from my SM-G930F using Tapatalk Edited September 15, 2018 by BIG Trev Link to comment Share on other sites More sharing options...
BIG Trev Posted September 16, 2018 Author Share Posted September 16, 2018 I tried a bit of retrobriting today but left it a bit late in the day and ran out of daylight. I'll give it another go later. It's looking better but still needs a bit more. Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
Jumpingmanjim Posted September 16, 2018 Share Posted September 16, 2018 Looking impressive so far. Can you do RGB input on this? Link to comment Share on other sites More sharing options...
BIG Trev Posted September 16, 2018 Author Share Posted September 16, 2018 Looking impressive so far. Can you do RGB input on this?No just G. It's a green screen monochrome monitor.[emoji16][emoji6] Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...

BIG Trev Posted September 17, 2018 Author Share Posted September 17, 2018 Well now I feel pretty dumb haha.It would be nice if it was colour. If I ever find a 9" colour tv I'd try a tube and chassis swap. Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
Jumpingmanjim Posted September 17, 2018 Share Posted September 17, 2018 CRTs scare the crap out of me, look at the size of those capacitors. I take it you've worked on plenty of other monitors before though? Link to comment Share on other sites More sharing options...

I take it you've worked on plenty of other monitors before though?No. I'm no expert just too stupid to know better.[emoji6] I've worked with 240v and 415v in the past and been zapped by both. These caps aren't what's going to give you a big kick it's the flyback and any charge held in the tube that'll wake you up pretty quick. You just have to be aware where the dangers are and be careful around them. If you're nervous about doing it then it's best left to someone else who's more confident.

Jumpingmanjim Posted September 17, 2018 Share Posted September 17, 2018 Haha, I learnt some new swear words when my cousin somehow managed to make contact with the mains electricity when he was doing some plastering back in the day. Link to comment Share on other sites More sharing options...
BIG Trev Posted September 17, 2018 Author Share Posted September 17, 2018 You get a 3 phase jolt and that powers up the swear word generator really well. I've done that a couple of times. We rented a factory for overflow storage and they'd removed all the 3phase outlets and someone must have turned the power back on. I learnt some new swear words that day when I brushed against one of the wires.[emoji38] Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
thegrunta666 Posted September 17, 2018 Share Posted September 17, 2018 I used to check a Cap was totally discharged by putting my pliers across it to drain the last bit of juice. Once the cap was still fully charged ( beer can size cap ) I put the pliers on it and "BOOM", the "shit myself" effect , blew me backwards off my work stool and onto the floor, also a sizable chuck of my pliers vaporised ! :realmad: Link to comment Share on other sites More sharing options...
