Question about Mitsubishi VS-60609 60" Rear Projection Television
I'm Getting a code of 2 -1 = X-ray protect (high voltage ot beam current) can you help
This means the anode voltage to your CRTs (RGB) is too high or your controlgrids have failed to slow the electron beam from the cathode down. What you need to do if you do not have electronics experience is to have a qualified TV technician take care of this problem. As a suggestion have him check the HV on the CRT anodes and the voltage doubler which the IHVT goes into. In any event get the set checked and repaired by a qualified technician.
I hope this helps

Tips for a great answer:
It could be a problem of cold solder joints, or solder joints
on the main board which have cracked over time due to thermal expansion and contraction
of the circuit board. Repair is to find and reflow the cracked joints. You may
want to consider hiring the services of a reputable repair professional to deal
with getting your set back into normal operating condition.
However TV's attempt to protect themselves from damage by
shutting down. Your unit has three main ways to protect from damage.
The TV monitors various DC voltage supplies. If one of the
supplies is missing. The TV shuts off.
The TV monitors excessive high voltage and beam current. When
the TV detects that one of these is too high the TV shuts off.
OVER CURRENT PROTECTION
This will activate if excessive current drain on the 130 volt
supply line. If the TV detects this supply line is too high the TV shuts off.
Most units made in 1999 have a diagnostic mode to help
determine the cause.
