[TechAssist] Re: Mitsubishi VS5073 Int Bright w/ retrace

Sorry, this unit is not setup for lightbox removal, I'm not sure but this
unit may also have a warning from Mitsubishi that the crts extend beyond the
metal frame and the crts can get damaged during transport.

Take a look at the CRT's 200volt supply from the IHVT, I think there's a 100
ohm or 10 ohm resistor that opens or gets bad solder connects on them,
dropping the 200v supply voltage, also check the horiz transformer for
solder and the regulators located on the deflection OR the stand up A/V
input panel. Not sure which one this model has, but those are common failure
points on the Mitsubishi's.
