is anybody willing to give a try on a repair on this board?
if the rom swap/reburn still changes nothing, i'll be willing to ship it out no matter where on this planet.
I changed the AD1851 and TL084CN chips and replaced the Y1 crystal and big cap near the heatsink -> still no startup boing or sound, no sound led activity :/

-> maybe the sound roms are the...

Looks like on Zenith chassis (with the box between flyback and anode cup) they used something like "H.V. CABLE WITH CAP AND BLEEDER", e.g...

AD1851 ~ 15$
TL084CN ~ 3$ / 10pcs
Problems with the AD1851 and TL084CN...
UPDATE:
No Bong at startup
No Soundrom errors on startup and test mode
No "Sound active" LED
Static on speakers
Then i found something interesting:
The board has solder pads labeled "AUX IN" and "LINE OUT".
I cut a mono audio cable and connected it (GND on "1") to AUX IN and hooked it up to...
I'll scan both sidearts and stitch it into a massive L+R photoshop.
Anybody interested in cleaning them up? My cab has some (minor) scratches and gouges in both sides ;)
Big thanks!!!
I'll order the MK1 sideart from rich anyway, great if the CP sides are included! (didnt know that, it isn't described on his website, but CP sides are included in the MK3 sideart)
