Title: PROTECTION MONITOR 50" HELP
Post by: ARCADEMAN on July 26, 2009, 01:41:23 pm
I have a WAVE RUNNER arcade game that has a monitor 50" problem.
When the Main power button is pressed, the LED goes Green and then Red .  I hear the sound of the monitor trying to turn on, but nothing. I hear the 2 relays on the power supply  goes on and then off. The fans work for a moment and then off.The fuses in this monitor look OK i test it.
Pictures of the monitor  is the same like this one  http://www.flickr.com/photos/impulsze/sets/72157600405829679/ .I have replays all the STK IC and a lot  of capacitors.Steel the same.NEED HELP   :dunno

The model appears to be a Mitsubishi VS-50SE1 50P-GHS41 if anyone wants to take a stab at it.
Not sure if the original poster can find an actual chassis number, but that might be helpful in research as well.

I rarely touch a projection set if I can help it.
HV shutdown, convergence IC's, pico fuses blown due to bad convergence IC's, caps,  :P

most projo's have various protection circuits that will activate on a fault . (a service manual would be quite helpful)
a visual inspection is a good beginning . start with the pwr sup. look for domed /leaky 'lytic caps-replace as needed..
same applies to the deflection pcb . also look for burn marks and loose connections .
loss of vert deflection will trigger shutdown. look for poor connections on the vert output ic.
if the HV does come up , the h out xistor is likely ok. however, faulty tuning caps /flyback/HV Distribution block can all
cause shutdown .
convergence failures can cause depending on brand .
i'm not familiar with Mitsu projo's , thus can not give detailed tips.
i'll see if i can find a manual .........  :dunno

good luck

Check the bulb.  TVs and projectors won't keep power if the bulb is blown.   It could also just not be pushed in completely.

this is a crt based projo ( i.e. red , blue, green crts) 
no uhp lamp or balast to be found in this one .  ;D

not found a print.  :(     it may be a "proprietary" model ...?

last one of these i had go was a fault on the power supply board,trouble is the fault could be anywhere-what you need is another one of these to swap until you find which of the boards is faulty
the problem i had was a blown voltage reg
