Convergence IC's are bad......

You can mess around with ordering them, and replacing them, and hunting for the bad resistors on the board and replacing those too, or you can order a new board PN BP94-01266a for around $160, and plug it in. You'll have to readjust the convergence manually afterward. Just did it on my set - works beautifully!

look for trouble in the low voltage and or high voltage power supply circuits. the popping sound could be an exploded safety capacitor in the horizontal output to the flyback transformer. the horizontal output transistor maybe damaged. chances are the low voltage regulator is also damaged.

My hcp4752 started smelling hot now the colors are


It looks like you have a problem on your convergence panel. Look for burned resistors near the STK-* IC's. One or more of the STK-* IC's may be bad. When the resistors get hot they smell but so do the IC's. You can replace the bad parts or you should be able to replace the entire panel then go thru a convergence alignment.

Burned out? How? Depending on the age of the TV, there are two boards, possibly a third if it's a later model. The most likely culprit is the PWR & DEFL board - P/N BP94-01266a, and it's readily available for around $150, but before you order it, tell us more.....Do you have sound, etc.

Line at top of screen


There are problems in the vertical blanking or scanning circuits. This is not something you can fix yourself at home. It involves troubleshooting the deflection amplifiers and scan generator areas to locate the defective components.

You will have to give the set out for service. I would suggest to get an estimate before proceeding. This type of repair can be costly for the labor to find the fault. If it is only generic type parts involved, the parts themselves will not be too expensive.

Double vision


My television is a hc-p4752w and the color convergence is way off. The red and green are not together and curl away from the top of the screen and bottom too. I tried to auto focus with only making the color separation worse. The tv is about four years old with lots of play time...
I am a aircraft mechanic with some electronics training so I don't mind replacing components I just don't know where to start and have no troubleshooting manual for help. Any help would be greatly appreciated!!!!
