Question about Philips 55PP9401 55" Rear Projection Television

1 Answer

DOWN HILL??? There is a problem with the picture running down hill (as I call it) If I watch a movie that is widescreen the space below the movie is much smaller on the right than it is on the left. I was told that the yolks need to be turned. Is that true? and if so how hard is that to do?

It only true is its like one color that is twisted. Remember there is 3 tubes in a projo. Red, Blue, Green. So if a yolk needs turning and the color is not badly out of wack then that makes it that all colors are out and it is hardly likely that all three are turned the very same way(misconscrewed) So this maybe an internal matter. In service menu there maybe a way to align the convergence or crosshatch of all three colors or maybe a resistor that has changed in value. Either way you need someone familiar with the set to work on it.

It depends what you're watching: For regular TV, cable, satellite and DVD then you just need to use the Aspect ratio button. It is the PIX SHAPE button. Make sure all your source boxes have their picture menus set for a 16:9 (widescreen) TV.

If you are watching Blu-ray, then the situation is different. Blu-ray expects that you have a 16:9 TV. If you use a Blu-ray player to watch a DVD, and that DVD is an older 4:3 shape movie, then you'll be stuck with the bars left and right. It's the player that formats the picture in that way. There's nothing you can do with the TV controls because they'll be locked to 16:9 mode.

Picture looks like it is jumping

Sounds like a vertical sync issue on the chassis board. However you also mentioned the picture moves left to right or vice versa which would suggest a horizontal sync issue. Either issue is not repairable by the DIY. Sync issues must be isolated using test equipment usually found in repair shops. My suggestion push it down a hill and enjoy the show then go buy that flat screen you almost purchased last week.

Alignment of picture is off balance

Yes but you will have to replace STKs both of them also check pico fuses and resistors. STK394-250s i think is what this set uses Go by STK numbers that are in your set.You can get Parts at Electronix 1-800-223-3205.

Most if not all DVD's are 16 by 9 even in 4.3 mode you are going to have those bars on this TV. Some television have a zoom feature to get rid of that but not this one.

Red tube going bad???

much to my suprise these tubes need to be re-juvenated with a crt shooter. this does not bode well with the so called king o the hill (sony). although after re-juvenating the tubes seem to hold up rather well.
