Amstrad CTM 640 repair (CPC464 monitor)

[@alan_wheredidiputit]

Well done! Hopefully you're at least halfway to getting the old thing breathing again. Complete with yet another new groovy playout track! Wonders never cease :)

As usual, zenners are not the jellybean parts anyone stock in a variety of valules. God damn those. However, STK modules are a pain in the backside. Excellent video as usual. Cheers from Argentina!

Ps ,can't wait for part 2 to see it working

[@alancawley8810]

I was gripped by the video - edge of the seat stuff - great entertainment. Ever considered Song for Europe? Loved the song - the style was contemporaneous with the hardware. Looking forwards to part 2 !

Very nice to see servicing this ! Thanks

[@AndyDoz]

Glad you enjoyed it!

Such a tease, from about half way through I was thinking "he's not gonna have much time to work on the actual computer bit if he doesn't hurry up". I never thought it was going to take you so long to sort the monitor out, but as you warned at the very start there was a lot to go wrong if you didn't do the checks. Well done so far and I can't wait to see next weeks epic. Thanks for sharing.

[@AndyDoz]

I did intend it to be one video, but the monitor needed time to sort. Sorry

[@wasdaletimelapse7658]

@@AndyDoz Don't apologise Doz, just make sure you add "part 2" to the next video🤣

[@richardh100]

well done again another great repair I remember being told years ago about the fake STK chips about the weight if they were heave too light fake Chinese ones😊😮

[@analoglooney]

Crikey Doz. You do like variety on your channel. From Quad to Amcrap! Do you remember those Amcrap TV's in the 80's that claimed to be stereo but weren't ? I think it was a ctv 2200. The company I worked for used to buy them in new for peanuts and take the Mullard CRT's out for the rental sets as it was cheaper than buying the crt from Mullard! Go figure. The rest went in the skip. 😆

[@AndyDoz]

Oh I do. They were awful, but an excellent provider of A56-540X! This is about the only quality product they made.

@@AndyDoz 👍

[@AndyDoz]

Did you miss the Arcam in between the quad and the Amstrad??

[@analoglooney]

@@AndyDoz Hi. No, I watched the Arcam video thanks and left a comment about the notorious sticky disc clamp. 🙂👍

[@audioorigami]

love it

[@johnrudden5251]

I believe I bid on the same machine on eBay Doz ha!ha Small world. I am looking forward to seeing your repair 🙂

[@AndyDoz]

Oh that's funny. Sorry John, better luck next time!

[@ashleycox432]

the first' computer' I ever used was an Amstrad 'wordprocessor' with top-mounted dot matrix printer that loaded software from floppy. I had no idea they also made microcomputers like this. Any idea what they sold for compared to the competition?

[@AndyDoz]

Considering the monitor was included, they were very competitive.

[@ThaVoodoo1]

Does anyone know where I can purchase a Flyback tranformer for the CTM 640 monitor?.

[@AndyDoz]

I was dreading mine being bad. Have donberg got stock? Email before ordering to check stock.

[@stevesje71]

Great repair and video, glad you don’t completely replace all of the capacitors. I do the same as you, replace the ones under stress that can cause other components to fail. Nice work 👍👍
