Is there a power adjustment dial on the power supply?

Hello all!

Not to sound like an ass - but no video and beeping is not the hard drive.  Those are BIOS error codes - the motherboard is trying to tell you what's wrong.  In the old days of motherboards - which this would be - 5 beeps would indicate an issue with the processor.  Have you tried removing any heatsink/fan and re-seating the processor?  Here is a great link on Wikipedia with some old codes http://en.wikipedia.org/wiki/Power-on_self-test (http://en.wikipedia.org/wiki/Power-on_self-test).

As a side note - I have actually heard of techs having luck with the freezer trick with hard drives...although I have no idea why.  If you have a drive that won't spin up - I personally have had luck giving the drive a quick twist of the wrist - it's kinda of like banging on a car starter with a hammer - just a dead spot in the contacts.

Dpalmi's post from Wiki was pretty cool to read about.
The beeps were never standardized and...
 
( Watch out ahead here...read with caution as your tongue might get tied up )

The different manufacturers had different beeps for different things during different years.  :200-

as I mentioned I dont claim to be a expert .
but have been dealing with MERIT -JVL-MIDWAY/WILLIAMS for years

have approx 75-100 machines on site in working order . have run  routes of machines in bar rooms /pubs etc .
all have had diff issues ..

as far as the issue that was first mentioned by the poster !!

he has no video

has a beep every 5 seconds from mother board ??

I DONT CARE ABOUT BEEPS -- BEEPS MEEN SH^^T TO ME WHEN WORKING ON THESE .. ALSO DOES IT CME FROM SPEAKER OR PART MEANS NOTHING --COMMON SENSE IS THE KEY !!


as I mentioned >>check all connections<<<  remove and replace is the way I check  !!
That way if you have a corroded connection you can see it and clean it .

of all the Merits I have worked on over 1000 counter top and caberet machines -- I have seen only a handfull of mother boards go bad .

as far as hard drives I HAVE SEEN PLENTY GO BAD !! TO BE EXACT I HAVE A DRAWER  OF OVER 30-40 HARD DRIVES FACTORY INSTALLED IN MERIT MACHINES -THAT JUST SH^^T THE BED !!

SOME YOU CAN PUT BACK IN THEY WILL WORK FOR A WEEK ? OR A HOUR THEN DIE AGAIN .

ITS COMMON .. 

THE OTHER THING I MENTIONED --DOES HE HAVE THE CORRECT SECURITY KEY TO MATCH THE DOUBLE DIAMOND 2 HARD DRIVE ???

did the machine ever work as equipped now ??

is the CRT FUSE BLOWN ?? it has a new power supply but the chassis fuse is dead ?? has that been checked ??
many of the models had a fuse where the IBM --115-volt cord plugs into in the back -is that fuse blown ??

do you see a faint glow on the neck of the CRT = CATHODE RAY TUBE --when the power is on ?? indicating the CRT IS GETTING POWER ??

what else has been done ?? did it work at any time before you had it ?? what have you done so far ??

pictures help also .. my guess is still a bad connection ribbon cable off or plug corroded -- or bad hard drive --

rocket

are you saying you replaced the ribbon cable from a known working machine on your machine ??

and you get boot disc error ??

if thats the case the hard drive is junk ?/

have you tried putting in another set of software ??

a diff hard drive and matched security key ??   then has it worked ??

thats what i would do -- to condem the mother board !!

ok I am not trying to stir up a fight here .. just understand what your saying ?

you say if you remove the ribbon cable from a known working MERIT MACHINE .

TURN IT ON IT COMES UP BOOT DISC FAILURE !!

what is the relevancies  of this concerning your machine ??

if you have a known working machine and pull the ribbon cable off the hard drive --it should say boot disc error or failure
BECAUSE THERE IS NO HARD DRIVE CONNECTED --TO BE RECOGNIZED BY THE MOTHERBOARD


in your case your hard drive is connected !! But I suspect is no good -- turning slow --wont spin up -locked etc
so your mother board is recognizing it being there .. but you have no screen ??

as I said in two post back --to confirm mother board is no good or problem ??

drop in a a known working hard drive with correct security key and see if machine comes to life ..

if it does then it was the hard drive --if it does not it could be the mother board -ribbon cable -hard drive - etc .

does that put us on the right track ??

A few post back someone suggested that the ribbon-cable may not be connected ( or bad ). I'm saying this has nothing to do with my problem. The motherboard should and would still fire up without the ribbon-cable being connected, go through the memory test and all that happy horse****...BUT....the motherboard would stop once it tried to load from disk and display on the screen BOOT DISK FAILURE. Just tossing out the possibility of the ribbon-cable being the problem.

I you can post a picture of the MITSUBISHI--BOARD YOU REMOVED front and back side -- with a better pic so we can see the words MITSUBISHI
would be cool .

I WILL POST SOME PICTURES  of  a few of the TELCO mother boards
plus the "ENDAT " MOTHER BOARDS USED IN THE MERITS -NOTICE THE PLUG CONFIGURATION OUT-PUT ANGLE OF THE
"ENDAT BOARD" WHICH IS A DEAD GIVEAWAY WHEN LOOKING QUICK .
