Chad - will do, thank you Possible issue - so the board does look charred in that area, BUT I am getting glow at base of tube and red led, several sites warn that a bad game pcb that is 'playing blind' (which mine possibly IS) can give illusion of a bad monitor, am I not best FIRST sending off game board for repair BEFORE I address monitor? Or does the pic tell us %100 repairs are needed? arcadecup.com - any opinions? $195 plus shipping Thanks guys Lee |

The LED on the deflection board in the monitor is the 'spot killer'. Basically, it's a circuit that shuts off the electron beam if the monitor is not getting a signal that is displayable by the monitor. It protects the CRT from phosphor burn in the center of the screen in the case of bad input. It also protects the CRT from monitor defects that could cause the same thing. Yes, a bad input signal from the game board can cause that spot killer to activate. Yes, a monitor fault can cause it too. And yes, a problem with the wiring harness can cause that even in the presence of a working board and working monitor. I always go through these Atari vectors in this order. Rebuild the power supply in the bottom of the cabinet and make any repairs to the connectors there. Move on to the AR board and rebuild that/repair connectors. Inspect edge connectors at the game PCB and make any repairs there. Power up game and verify that you're getting good power at all test points on the AR and on the game PCB. Once you get to this point you're ready to address the monitor and the game PCB. If you don't have good clean power and good stable connectors the game will never be reliable even if everything is functional. The molex connectors on the Atari games are problematic at this point. The pins are easily bent, they're loose in the housing, and you're going to be cycling them quite a few times as you restore the game. It is often worth the trouble of repinning all of the square connectors just to be sure. |
