Re: PHILIPS MODEL # 46PP93 0217 40 INCH.
It may be the fluid in the CRT or the convergence chips are bad.
Here are some of the most common symptoms and example photos of a convergence problem
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should bePHILIPS MODEL # 46PP93 0217 40 INCH. - 2c07611.pngThis is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Some of these TV were equipped with very short connections from the infared board to the small signal board. Remove some of the shrink tubing from the wires of the IR cable to relieve stress on the individual wires. Trim the other end of the cable as well. We are talking about one half to three quarters of an inch.If this does not help you will need to order a new IR cable. Please show this info to an authorized Philips dealer and have them do this for you. Thanks for asking and show a few hands of support.
If it is a Philips rear projection TV I am sorry to say that you are stuck with it, just like I am... I have a 52" Philips rear projection model myself that I got from the company store when I worked for Philips... since you mentioned convergence my bet is that you have the same set or a similar one.
Have it exchanged for a new one. Either the control board is faulty,or the panel itself has failed. If the panel is defective,then you're gonna get a replacement anyway being that the panels are more expensive in part price than the entire tv set. If its the control board,there is hope for a technician fixing it,but I can't advise a John Smith repair.
hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it? When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..
