Question about Mitsubishi VS-7083 70" Rear Projection Television

1 Answer

Mitsubishi TV Model VS-7083

My television is running horizontal lines. It seems that any floor movement triggers the TV to jumps to flickering horizontal lines. If I turn the TV off the problem goes away and if anyone stumps or walks to close to the TV the problem continues. Any suggestions?

The deflection board and/or smps have most likely ring-cracked on one or more components on the board due to heat stress. It's not an expensive fix at the moment, but continuing to operate it this way will place additional stress on components like the regulator and they will eventually fail...
If you're taking it into the shop for this repair also discuss with your tech to do the following per Mits bulletin: APPLY FOLLOWING CIRCUIT CHANGES ON PCB-SIGNAL: A. REPLACE R2K8 WITH A 1K RESISTOR (BASE OF Q2B2). B. REPLACE R2K3 WITH A 47 OHM RESISTOR (IC201 PIN 50). C. ADD A 100PF CAPACITOR FROM BASE OF Q2B2 TO JUNCTION OF R2L0 AND R2K6 (GROUND).
Have a great day!

That model uses the 392-040 chips and for that matter you can look inside to confirm the number right on the chips.

Mitsubishi vs-55707 or vs-50707????? bouncing horizontal lines weird color

If the picture looks like a 3D then you have a convergence failure.
I would suggest to visually inspect the STK Ics for dry or crystallized solder joints.

VS-45607

sounds like a defective cappacitor or leaky diode in the deflection circuits. Unless youre comfortable working around the high voltage circuits of a rear projection set, it may be best to call a reputable repair facility that is famillair with mitsubishi products.

No Blue. Horizontal Lines.

Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.
