Re: Convergence circuit Panasonic PT-51G54CA
Look for 3 black things about the size of 2 matchbooks on a big heat sink. The part will begin with STK. You can buy at MAT electronics.com for around $12.00 each. Can you do the repair, yes if your skilled and have a steady hand. If you find the STK's then also look for 6 green round fuses or coils that are burned. change them also. Good luck..

Picture colors lines R,G,B mis alingments,have colors shadows pictures or 3D pictures look alike?Yes.The tv convergence board is dead,the board require changes 2 STK convergence ICS and some or all of it resistors too.To fix the tv convergence board.U must have tools like a soldering iron,a desoldering pump or a roll of desoldering braids and also can do soldering work?Yes,tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit belong to ur tv model and make to repair it ur self.Or the shop will cost u like $300-350 for parts and labors.
Yes,this problems is 100% convergence problems,it dead.The tv have colors lines R,G,B mis alignments anywhere in the pictures,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.
thats the convergence circuits needing repair. You can repair it yourself for around 50.00 with the convergence repair kit for your model from www.tvrepairworld.com the kits contain the parts and the CD with instructions.
A projection Tv convergence amps can be fixed/replaced and a competent tech will also test the yoke return resistors as well as various other components. The amps themselves are about $20.00 a piece (usually two in the circuit) depending on where they're pruchased. I suggest ACME out of Florida - only because it's real easy to buy fakes. Get only Sanyo originals and to do that you need to make sure they're purchased from a reputable supplier.
Did you do a repair on the convergence circuit? If so it would be ok to do an adjustment in the service menue. But if you have a problem in the conergence circuit and you dont repair it first, making adjustments in the service menue can do damage to the DCU and cause you major problem in the future. If you have already repaired the convergence circuit then let me know and i will get you the codes.

The STK392-110 is a convergence correction circuit IC for video projectors. It incorporates three output amplifiers in a single package, making possible the construction of CRT horizontal and vertical convergence correction output circuits for each of the RGB colors using ust two hybrid ICs. The output circuit use a class-B configuration, in comparison with the STK392-010, realizing a more compact package and lower cost. www.partstore.com
