Maybe dead.

Two reasons;
One, is the Heatsink on the SMPS in center of board
is Hot Ground and can not touch the metal back!!
If it does then replace Fuse Mouser#504-pcd-5-r
and the Bridge rectifer #GBU6K from Mouser..
and it could for no reason,even if game not moved
at all,its that close to metal back.Need to install
plastic cover over Heatsink,newer models may have it
on already,that use that powersupply in it.

The second reason is the Cap's in Powersupply
C15,470/16v
C16, 47/16v
C21,470/16v
C19,220/35v
C13,1200/10v
C14,1200/16v
All domed may not be that way on every SMPS
but they will dome so replace all at once.

Second; Symptom could be Lcd slow start or not at all or shuts down
but turn on may work,i'm having the techs bring in the boards
to repair before they breakdown. Good Luck!!
 
No backlite's

Power Led green
voltages good to the inverter board.

Found open SMF Surface mount fuse,3 amp
no need to replace it untill you remove the shorted SM IC
I just bought a used inverter board from e-bay to findout i also
need Lamps,assuming the e-bay board is good.

Now going to try and replace a few lamp,its not easy when
you touch them to remove they break.
Almost eveytime i try..Is it worth trying?
With the prices coming down or subbing with other micro displays?
With the boss's money i will order some lamp's to try..
and post what i find.
