Color classic - Replaced caps -> clicking analog board

[daanvdl]

Maybe something nice to share.

These are the Conrad part numbers for ALL the capacitors on the Color Classic analog board, and i can confirm these will work and fit:

Note: Conrad doesn't sell any 330µF capacitors that will physically fit, but the only 330µF capacitor on the board is likely not damaged.

Hi, I see RL54 as 30ohm 1w on https://powercc.org/640x480/ otherwise it's listed as 330ohm as stated above. I'm looking to figure out my issue listed here: 



 any thoughts?

Hello, thanks to your contribution and the photograph of the board I have been able to finish repairing an analog board on my Color Classic but the area in the photo gets very hot. Does anyone know if there is any modification that can improve the temperature?

 

[pizzigri]

You mean the caps get hot? Or the line output transistor? It’s the one on the heatsink. If this gets hot, that’s more or less normal, the caps are film so if they get hot maybe you should check them.

 

[fidelware]

The capacitors are heated and they're new

 

[pizzigri]

OK, so you changed the electrolytic caps - there are only two in the oval, as one is an inductor - oralso theblue square ones, that are film? Do you have a thermal image of the hot spots? There's a power diode between these film caps and the line output transistor, DL4 I think, that also gets really warm. Film caps should not get really hot.
