SOURCE: JVC DLP MOD#HD55G466 what is the

Ballast board gets voltage from power supply connector CN90BL and volts readings are as follows:
Pin-1 = 380V DC
Pin-2 = Ground
Pin-3 = 15V DC
and output of ballast board would be 12,000 volts AC that goes to lamp to generate spark in its electrodes to produce high bright light.

If you get volts on input of ballast board but still lamp does not fire up then ballast board is not working.
Ballast board part number is QAL0765-001 and available with for $125
Hope these info will help you.

If the new power supply did not make it work, check the circuit where high voltage is, or whether you have any surge arrestors short circuiting.

Jvc lt-37e488 will turn on with just a black screen and no noise. THe menus cannot be accessed and the the buttons will not even work to turn off the tv.

You have either a power supply board malfunction or a main board gone bad. If the voltages from the power supply board are all present and correct, then the main board is at fault. TV Parts Universal TV Stands DLP Chips ShopJimmy You can get parts here.

What could cause Transceiver to shut when power output is increased over 40 watts?

My first guess would be that you have a bad/poor antenna,coax, causing high reflected power, next would your power source. You will need a 25A or higher rated power supply, with clean 13.5V power to run at the higher power levels. Meter the power supply voltage when you xmt at a lower power level, maby 30w, watch for drop in voltage. If voltage drops (some) at 30w, most likely supply won't hold voltage up at your 40w and higher power levels.

How do I reduce 17 volt DC to 14.4 volt DC

Depending on the device, the 17 volts might work fine. A resistor would not be a good choice for the voltage drop, as the drop would vary with current demand. A voltage regulator is what is called for. The cheapest solution would probably be a new power supply.

706 mk 2 shutting down on fm high power

sounds like voltage drop. check that your power supply isn't dropping in voltage when transmitting. FM draws a large amount of current all the time, and not just on peaks. The 706 will shut down if the voltage at the radio drops to about 11 volts
