Help Needed With WGM2792, No Picture

[kardenm]

Need help with a 25"(?) CRT from a Silver Strike bowling game.  Sticker on the chassis says WGM2792.
The game powers up and I can hear the game playing, the monitor is getting 120v and the fuse is good but that's as far as it goes.  No picture, no HV.
There is a small relay (H1AA012T) on the board in the power supply section.  This relay is ticking (turning on and off) about once a second.

Any suggestions on where to start would be greatly appreciated.
I will attempt to attach pics of the board, relay and cabinet.
Thanks!

these can be very difficult to repair
first thing to check is the HOT and the fet's,caps will need checking also-look for any burnt components like resistors
if the HOT is short you should remove and inspect the deflection yoke for corrosion,they used a paint around the neck that over time flakes off onto the inner part of the deflection yoke and rots through the insulation of the copper wire thus causing a short-if this is not put right then no matter how many times you repair the chassis on power up it will fault again
flyback is another component that is a common fault

absolutely tons to check on these and sometimes you are lucky and they can be an easy fix,other times not so

wells gardners website has a fault guide to these and there are fault guides on other forums,these will be of great help to you

of course quickest way to sort this is buy a replacement chassis,seen some on ebay but if your yoke is short they will fault quite quickly

its a 27" crt btw,the wgm2792 code means first 2 digits are size and second two digits are model number

Thanks grantspain. Appreciate willingness to help and extensive knowledge.
Doesn't sound very hopeful and may be beyond my capabilities and/or patience.
I'll try the WG website. any specific links? Also may try ebay to buy another chassis.
I would assume there is a way to test the yoke somehow before I buy a replacement.?
I'll see what I can figure out and post back.

trouble with testing the yoke is that it will almost certainly read ok until it has been powered-then the short will occur
only way to be sure is to remove an inspect
