Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television

1 Answer

Arcs at the Top and Bottom of the screen!

I've replaced the convergence chips because I was told that would fix everything. But I still have a concave screen and there are arcs on the top and bottom of the screen. Is there something else I need to replace? Please help???

You will find small 1/2 or 1watt resistors close to the ic's, you must measure them and they must be exact ohms. I believe you'll find a couple open or have changed in value, I hope the new Ic's haven't been fatigued. That should fix your problem.

There is a concave on the top of the screen and bottom of the screen whenever i try to readjust the convergence i can get 6 out of 8 crosshairs perfect but i cant get the top and bottom due to the concave...


Hello; You have a failed convergence board. JVC does NOT give me ANY info. They won't even talk to me on the phone! On some sets, there is a digital convergence board and a power convergence board that actually drives the convergence yokes on each of the 3 CRT's. If you have both, either one is bad and probably expensive. I recommend people Don't buy JVC products due to their bad reputation. John

My 57hx81 has a slight concave bow in the middle top to bottom


Sounds like a problem in the vertical sweep circuit. Check voltages to your convergence ICs. If they are  not to spec then look for bad fuses and capacitors on the power board. These will throw off the DC voltage to the convergence chips causing the bow effect. I've had a single bad pico fuse ($1) cause this symptom.

Lots of Blue shadows off to side. concaved picture almost


HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

You have a convergence chip problem. You need to get a kit from www.TvRepairKits.com.

Note: The longer you run your set with a convergence problem the more problems you will have. Turn it off and get it fixed.

Picture is concave on top and bottom. With ed and green ghosts.Worked fine, turn set off and on about 15 minutes later and picture was as described. Help!


The convergence chips in your tv have gone out. They control the three picture tubes and align them so that they create one picture on your screen. I recomend having a qualified technican replace them and realign you convergence. Thanks.
