Hi Thanks for using FixYa. Usually
this happens when the Light Engine has gone bad, and I should say this is a
common issue with Projection TVs. There are three tubes/mini LCDs inside your
TV- green/yellow, blue and red. When the set heats up over time of usage the
screens tend to break resulting in leaking color everywhere. The cost to get
this fixed by a professional should be around $300 depending on the parts that
needs to be replaced. Please do accept the
solution if the issue is resolved or else revert for further assistance. Thanks Rylee
Bad convergence Amp ics mounted to large metal heat sinks on deflection bd.Sony parts around $40.00 each-generic approx 12.00 ea.The board must be pulled out of chassis frame to unsolder the ICs.and some alignment will be needed after replacement.NOT a do it yourself job unless experienced at soldering and desoldering.
I am slightly confused about the model of the television, because a 46F500 is a rear projection set that doesn't have a lamp. It has 3 picture tubes and I have a few of them in my shop right now that have the problem you reported. What we do to this set when it develops a convergence issue is to check each resistor around the convergence chips for discoloration, and replace any of them that have changed in value, along with the STK392-150 ic's. If you don't have an ohm meter and solder/desolder equiptment, you can usually get a shop to do this repair for 150.00 to 350.00. Parts will be 50.00 and labor , the rest, depending on the quality of repair shop that you use. Good luck, Russmann.
