yes that makes more sense, thanks 👍

Ok right, C13 is aluminium electrolytic do they pop?

Hi all, just settling in for a Lemmings session on my old faithful Q650 and a loud pop followed by the mains tripping occurred. Looking inside the PSU it seems like it could be the capacitor at C13, the board is quite greasy looking here and there. On the back you can se the trace has been...

Hi @maceffects +1 for a SE board if you can keep me in mind, although where are you re. shipping? I'm UK. Cheers!

@olePigeon good shout I'll get some switch cleaner in there (never seen Dioxit in the UK). Thanks! @croissantking really useful. I'll have to sooner or later but sooo many caps! 😥

Oh yes for sure it has other problems, but this is much better. Need to track down a line output transformer.

Afraid not, only a small Amount of adjustment available, perhaps could change for a different value ?

Ah brilliant thank you, there was a little bit of anti-clockwise movement. Made it much more useable 🙌

Is it this one at the top? seems to adjust focus but got it as good as it can. I've not taken it apart yet

thanks for considering it @imactheknife, the adjustments at the back are all position and width/height. One on the side controls is brightness the other is contrast, turning brightness does nothing, wonder if it's the pot? but they don't break, do they? Actually turning the brightness dial makes...

Yes this is as good as the brightness/contrast can get, the back adjustments don't affect the washed out look

What were your symptoms pre re-cap? I've got a contrast and blur issue posted an image here: https://68kmla.org/bb/index.php?threads/13-hi-res-monitor-softness.47083/

Hi all, I've had the 13" trinitron in to get looked at, there's a slight improvement but still some kind of offset, low contrast and softness. The TV guy said it needs a new line output transformer, but can't source one. Any other opinions on this? considered a re-cap perhaps? n.b. the pink...

Thank you!

Nice job! I've considered doing mine, its a lot of caps isn't it? Do you have a list at a all ?

Pretty simple as I recall, this is helpful . then just follow Fallen6 method above. The breaks can be very very small.

I didn't, I had the new board to jumped right in to replace 🛠️

Done! new hybrid from Supesvga and now running happily from battery. Not easy to get out cleanly but took my time, had to chop the old one up but all ok. Big shout out to @SuperSVGA and @androda for their hardware projects for the portable 🙌
