Question about JVC HD-52G787 52" Projection Television
My JVC HD-56FN97 turns on, isn't very bright, and the colors are all wrong. Everything is in a shade of green or purple. What is wrong? Lamp was replaced and nothing changed.

Hi, don`t know if you`ll be able to find this but D9405 a surface mount diode on the main power supply board is a known issue for yours and many other models, it has to be re-soldered not replaced, other joints in area may also need to be "touched up", other than that I had one where connector CN310 was not seated correctly, one side of plug was cocked way up, other than those 2 you may have a bad ballast (board that the lamp is connected to), Be sure that the lamp door is securely closed as they have a switch built into them and if the switch is not closed the set WILL NOT start, hope this helps you out, BMW Rider

This is a typical example of a convergence amplifier failing (any brand would be the same).
More than likely there are 3 amps and they should all be replaced together. Parts shouldn't be too
expensive but I would expect approx $100 US in North America and about £100 UK. Bear in mind thats for the repair not any transportation costs to/from the repair centre.
