Question about Mitsubishi VS-50609 50" Rear Projection Television
I have problems with this TV, based in codes, my problem is located in deflection system. Horizontal deflection is O.K., but Vertical is not... would you help me telling me where vertical pulses are generated??? I have scope.
In advance, thanks.
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) Check b+ goin to flyback durring turn on, if it does not come up to spec then change flyback. Also check the h-output and b+ fuse. report back to what you found durring these checks.

As far as I can recall, this set uses a standard vertical IC. Check that first. It should be an LA7837 or somethint similar. Also, check the capacitors in the same circuit as well as the supply voltages to the chip. If that fails to resolve the problem, please update this and we'll move on to other areas.
