Question about Philips 28PW6506 28" TV

Philips 28PW6515-05 flat screen TV

Hello, I have a Philips 28PW6515-05 flat screen TV. For sometime it had two colour related problems. 1. Until few days back it used to start fine but after running for about half-an-hour a fluctuating pinkish tint used to appear on the screen. Tapping of chassis appeared to reproduce and fluctuate this effect. The tint used to vanish when the TV is turned off for about 10 or so minutes. One day I did not turned the TV off and the picture turned pinkish, then greenish before finally covering the screen permanently with pinkish purple colour with thin horizontal zigzag strips (from top to bottom). Strips moves only slightly. Screen selection button appear to change screen dimensions (wide screen etc.) but channel change etc. appear to make no difference. I even tapped all circuit board (with plastic rod and tv ON) but no effect on this purplish/ pinkish screen. There is no sound either. I have looked on all circuit boards, every thing appear fine and all solders looks healthy. Any clue if it recoverable and how? Any help will be appreciated. Thanks.

    Thanks techman for your quick reply. There are two boards attached to CRT of this TV. One at the back and the other in at the beginning of the tail of CRT (at about 45 degree angel).

    As I wrote earlier, apparently all solders looks fine and tapping and pressing of circuit board against socket (while TV is on) does not make any difference.

    Should I ( and how?) remove the socket that connects the rear board into CRT and try to refit?


  • Searcher Mar 27, 2007

    Considering fragile nature of CRT, before I attempt, could you please confirm that the socket is simply push fit and it can be pulled back straight? how about using wd40 to loosen it?

    Rest assured I will rate the thread before posting the final outcome.

    Hi techman,

    I checked the socket. Some pins were blackish. I did clean them with very fine emery paper. But the situation is still the same. Is there any way they can be checked with continuity tester or so.

    If this is not the problem, what else it may be?

    I can access Service manual of Chassis A10E over the net but it is a bit too complex for me to understand...

    I did try to enter customer service menu by pressing mute on the remote and one button on tv control panel ( procedure recommended by service manual) but the set failed to enter in in CSM and screen remained what it was.

    I did not try to enter into Service Default Mode by using RC7150 (which I do not have) or by short circuiting the jumpers 9261 and 9262 (as recommended by service manual)

    I do not know where these jumpers are and even if I find them, I am not clear as to how I should proceed.

    Thanks for your assistance techman.

    Philips 26PF4310/10 pink picture. TV runs normally for days then all of a sudden picture flashes pink. No way fixing it by any remote or set-top controls. Pulling power lead for a minute resets it and set may run ok again for a week or so.

You have a bad connection on the CRT board thats mounted on the end of the picture tube it sounds like, or the socket on that board that plugs into the TV set is intermittant or has a bad solder connection on it. Good Luck

    Yes for sure try that and look for burnt spots or marks. Be very carefull as the tube is easy to break and please make sure the set is turned off. Dont forget to rate this thread.

    Yes you kinda wiggle it a little, very little, side to side while pulling on it slightly. and no, no wd40!

    Ok it may need just an adjustment but if I am not mistaking, this is done through the on screen service menu, and you really should have a service manual to attempt these adjustments and I just looked and I do not have one to share with you.

This problem is known as image retention and is a problem with the PDP. Turn on the set when you see these spots and see if they appear on the image too. If they persist, then its time to use your warranty to get a replacement.

If the lines across the screen are made up of coloured blocks, then the problem is likely to be a weak signal.

Digital channels are broadcast in groups called multiplexes. Sometimes one multiplex may have a weaker signal than others, and so you experience problems with up to 6 channels when all others are ok.

If it is only one or a few channels then just wait and see what happens, because it may be transmitter works.

If you have problems with all channels it could be a connection or antenna problem.

If the lines are just straight lines, then try resetting the TV as follows:

Switch on the TV

Press and hold the menu button on the side of the set. The settings menu will appear. Hold until the menu disappears again.

When you release the button, the TV will take up to about 90 seconds and then reset.

The TV will then show the original screen when the TV was new.

Press ok when shown.

Set language and country settings.

Move down the list and press ok to re-install all channels.

Problem, please help

The unit should be under warranty. What you're describing is not normal and I would attempt to get a replacement from the place of purchase or take the unit to an authorized repair center. Below is the Philips support page for your unit. You can check warranty status as well as request repair.
