Betson Imperial 27" Multisync blown out

[antony30bc]

I returned home yesterday from work to find my Arcade Monitor (Betson 27") had no picture, and was exhibiting a constant click click noise. The light on the control board was on indicating power was supplied. This was after 4-5 months of having the monitor function fine.

Doing a Google I noticed the reviewer at retrogames had a similar issue. I called Betson and they were nice enough to say if I sent the boards in they could repair it and send it back in a day or so.

My issue is I am not sure how to go about removing the boards, and am concerned about receiving a 60,000 volt shock by doing something stupid. Does anyone have information on the steps to do this with this particular monitor.

The monitor did not ship with any information etc. All I had left to do on the arcade was get a good marquee and sideart printed, and install my home made speaker grills. What terrible timing.

Appreciate any help provided.

Not good news for me either, as I just bought a betson a couple of weeks ago.

There is a link to the service manual on retroblast if you skim through the review.  As far as disconnecting the boards.. I'm not sure.. but with the high voltage you need to be careful.

I heard somewhere, can't remember where, that if you have a fan blow on the monitor it will increase the lifespan.  4-6months though.. seems like awful short lifespan for an arcade monitor.  They probably take much more abuse in an actual arcade.. I wonder how often they need replacement there?

if you dont know what to do i suggest getting a TV repairman do it for you !

you need to discharge the stored voltage in the tube where theres a thick red wire going to a rubber suction connector to the back of the tube.

extreme care needs to be taken as theres 60000 volts in there. IT could kill you or at least send you across the room.

not going to detail the procedure as dangerous if you dont know what you are doing.

[edit] just seen top sticky thread in this forum - suggest you read it!
