monitor help plz

[bradster25]

   new to arcade machines..i got my first machine and the monitor wasnt hooked up i had a buddy of mine that has a few machines come hook it up but we got some smoke comeing off the monitor not off any wires but what looks to br around a metal pice im not sure what would cause this it it has him stumped aswell by the location of were the smoke is comeing from any help would really be helpful..is is a 19 inch Hantarex 900e....i got pics if needed..thnx

forgot to add the tube get really bright be4 smokeing

blimey smoke everywhere,the 900 had a 4 wire plug mains input which should have 240ac for degauss and 120ac for monitor maybe your friend wired around the wrong way-take a picture of where the smoke came from otherwise we will be guessing for weeks
i suspect if its the voltage around the wrong way then your bridge rectifier circuit would have blown along with the mains smoothing cap and fuse
if its just a coincidence and the monitor was already faulty then look towards the horizontal output transistor or frame ic or flyback transformer

ok this monitor only has 2wire not four well add the ground so we will say 3...this is a 900e..how do i post pics?

pics of monitor

[bradster25]

looks like right  under the metal

that is modified for the u.s market so disregard the 4 wire plug,yours just uses an isolated 110v ac input but still look for the bad solder joints

[grantspain]

wow thats one old monitor,the pictures you posted don't show anything i would be concerned at,with something that age you have to look for bad solder joints and at worst the flyback transformer-by the look of your chassis it seems it may have been stored somewhere damp

[bradster25]

so were do you think the best place to start is?

[bradster25]

ill post a few more pics

[bradster25]

pic....

[grantspain]

very difficult to see but the red lead from the flyback to the anode cap on the tube looks burnt,is this the case?if so you will need a new flyback transformer(if you have any damage on this lead it will arc across to any metal work blue sparks

[bradster25]

thanx for the help i just went ahead and got a new monitor...it was the yoke that was smokeing

[grantspain]

first time i have ever seen a yoke smoke ;Di reckon your anode lead was arcing to the yoke deflection plates making it look like the yoke
