My Asteroids Deluxe (new purchase) is having monitor issues. Aside from the image being faint, the image fades to nothing in the center of the screen. I've ordered a cap kit from Bob Roberts but are there other possible issues involved? I was reading about the HV Diodes for the V2000 and difficulty getting them. Does this sound like an issue related to the diode?

The image is so dim, the pictures of the screen wouldn't come out.

Get a meter on those large sand resistors at the edge of the baord. If they don't show at least 3.8 ohms resistance, both need to be removed and jumpered.

While you're at it, meter that one in the HV cage too.

Does the image change at all after being on for any length of time?

Rebuilding these monitors is almost always a must. Get the deluxe kit from Bob Roberts (the one including the bottlecap transistors) AND get the replacement pot kit too. $18 plus shipping should get you there.

If you need a HV diode, LMK. I have a spare I would let you have for less than you can get it for from Mike's Arcade (bought it, didn't need it).

Definitely on the HV diode! Thanks. I finally figured out how to post pictures. LOL.

I'll test those resistors when I get home. If they are not reading at least 3.8 ohms, I should cut them out and just jump the connection? How about on the HV board? Same thing?
 
The image does get larger until it is way off the screen. The center of the picture fades to black toward the center. The image is very dim on the outsides.
 
Jumper deflection board resistors: YES
Jumper HV board resistor: NOT SURE (I think 'NO') - better replace if bad
Flyback: NOT available. Only way to get one is to buy a reclaimed one.


PM me for the diode.

I would say no too. I believe it is something like 18 Ohms,15 Watts (you should check the schematic to be sure). I remember getting a 15 Ohm and 3 Ohm from Bob Roberts and soldering them in series.
 
The flybacks on those almost never fail. I bet a cap kit and a new HV diode will have you up and running in good shape. Just remember the white band on the diode goes towards the picture tube in the connector. Also, don't forget to reflow every plug in header pin on both the deflection and HV boards.

Don't forget to clean the monitor overlay and 1/2 silvered mirror in the cabinet. Until both of those are spotless, you'll be chasing ghost using them to diagnose monitor image problems.
 
That's good news about the flyback. I cleaned the mirror and pulled the monitor out. I should have caps today and will install those tonight. I will also check the sand block resistors. I won't have a high voltage diode for a bit.
 
I found the cap kit list online somewhere. I went to all electronics and bought the caps. A friend of mine had a HV diode that was a NTE502. Similar HV Diode but much longer. We cleaned out the HV Diode cups and installed the NTE502.

The monitor looked decent but was still pretty dim. I have a rejuvenator. We hooked that sucker up and it appeared that it was in bad shape. We blasted it and now I have a beautiful, new looking monitor. Sharp, bright and clear.

Thanks guys!
