Just upgrade that ---maternal-smurf--- to a 27" Asus G-Force 4K LightWave Super-Dimensional LCD and be done with it.

Or Arcadecup.com. If it can be fixed, he can fix it.

Quite honestly, there are now probably a single handful of guys here at BYOAC that could help with anything more advanced than a cap kit, since most builders now are keen on LCDs, slim cabs, and Widescreen HDMI TVs and know nothing about arcade CRTs.

Send a PM directly to Buffett on KLOV. He can probably help.

Edit: Buffett is a member here, too. Send him a PM. Maybe he can post the answer here as well.

No offense intended, Grant. You're certainly one of the two or three people here that knows how to fix these things.

well i have been repairing coin op since 86 and i run a company called error 24 in the u.k so i should know what i am talking about,fixed my first machine aged 10-it was a centipede

what i was getting at is the component is on the blue circuit so isolate the blue gun by desoldering the pin of the crt socket,then see what happens

Just some thoughts, you are using the schematic while troubleshooting, right?

There are some voltages listed on there that may help to narrow down.

Like Grant says, these components (c804, r811) are in the blue circuit.

Grants advice on removing the blue gun from the circuit of course makes sense.
I wonder also beside that, would it be beneficial to remove q801 from the circuit, as it is the first point of the blue circuit after out1 of the ic
