Question about Mitsubishi VS-60703 60" Rear Projection Television
Last night it was fine and this morning there is sound but no picture. the menu comes up but looks like it is displayed on a bowed screen so i have the red, green and blue letters all just off of each other. then this afternoon it was ok again.
This is a common problem on projection sets and if you have someone carefully resolder the pins of the convergence chips, it will probably solve your problem. If you continue to use the set, the amps will fail and leave a dead set condition. What needs to be done is to disconnect the power, remove rear cover, loosen all snug wiring making sure to mark any wires that you disconnect, remove screws holding chassis in and undo plastic hooks at front of chassis, access bottom of circuit boards and with low wattage soldering iron resolder convergence amps, reinstall chassis and rehook all plugs in original places especially ground wires and high voltage leads, and test. If the soldering iron is too powerful it will damage the chips, also, be sure each solder joint is clean and not touching the one next to it or you will fry circuitry. Hope this helps. Russmann.
