Question about Philips 27PT6441 27" TV

9 Answers

Horiz. lines across top of screen.

Spacd lines across top of screen, perhaps 4 or 5 inches. Sort of "folded" over picture. Width of lines narrowing in a bit as the band goes lower.

Looks like vert. drive is excessive or non linear.

    Will study schematics to see which cap(s) most likely. May take weeks at the rate I work. Thanks for the tips. Phil.

    Same problem with a 32PT5441/37

  • Doc69er Jan 18, 2008

    Hello, Yes I have the same problem...Vertical white lines across the top of the screen.

    I'm willing to DIY repair if only I knew which factory parts and part #'s need to be replaced.

    Any help would be greatly appriciated.

    I have the 27in 6442 model with idential problem. I don't have the schematic so if someone could identify the capacitors that may be suspect I would appreciate it. If not where can I obtain a schematic at reasonable cost?

  • philadams6 Feb 20, 2008

    Yes, I've narrowed it down to these same 2 caps but as yet haven't had the TV to make the change to verify that it will work.These caps are in location c8 on the board parts layout.

    Yep I have this same exact issue, it's annoying but can view tv with it, not that I want to. I just recently had to replace the little fuse for the power by the cord on the inside of the tv. That was easy, this sounds more like you need to know how to possibly solder or have an electrical degree, I have neither. Is this something easily repaired by an amatuer? If so, where can i get easy to follow instructions?

    27PT6441/37 is the model I have.

  • twnall Oct 16, 2008

    the tv won't work and we're not sure if its the fuse or not because we had to replace it before and we don't know where it is in the tv

  • mwatson891 Jan 30, 2009

    We have the same problem with white lines accross the top few inches of the screen. When the TV initially starts when the screen is blank just before the picture comes up, there's a red, green, and blue line about a third of the way down the screen. If these are capacitors causing this, has anyone determined which one's should be replaced. Thanks

    sorry didnt post the link properly for the tv chassis diagram/schematics

  • David Holland May 11, 2010

    I have the same problem, yet it took 4 years to happen. I guess Im one of the lucky ones. To replace this capacitor do you have to discharge the CRT or the capacitor or all of them? A little nervous about getting a helluva jolt! I did find a site with diagrams and such on these models with the same chassis.Click here for it. All you have to do is register for the site(takes just a couple seconds), it is FREE, and then you can download the manuals as a PDF.

I agree with solution #2

I recently had my phillips 27" model 27PT6341/07 repaired after warranty expired due to white lines appearing at the top of the screen. The shop advised that it was a capacitor giving me the problem. So, after getting it back, I examined the repair job and the shop had replaced a capacitor at the back of the main board, next to the rear rca inputs. It is labeled 10uf 100v. I was told that it would fail again soon because it is a manufactures defect. For me it is at location 2465. Here are a couple of photos of the part.

Good luck,

In my case I corrected the problem by replacing tow capacitors.
The model is 27PT6442/37 which by the way is chassis L04.1U used in many models including 5441 and 6441.
The caps were #s 2463 100u, 50v electrolytic and 2465 10u, 100v electrolytic. I replaced both as I was not sure which one was at fault. They cost 25 cents each. They are located next to the high voltage transformer along the edge of the main board. If you need diagram send me a note.
Thanks to others for suggesting where to look.

Rhanks a lot guys! You are the angels of the web. I replaced cap #2465 10uf 100v with a 10uf 250v and my TV is great! Didn't even have to buy the cap - I had some old circuit boards from appliances I had thrown out, found one there. Wonderful work. Thanks again.

Problem: Horizontal "folded-over" lines across top of Philips TV.
Solution: Replace 10uf 100v Capacitor w/ 10uf 250v at 2465.

Notes: Philips 27" Flat Screen -Analog/Digital -2006.
Solution #3 is best since the original 10uf 100v capacitor is likely to fail again. There is no danger since the Capacitance (10uf) is the same in both. The larger capacitor can handle more volts (0-250v). If increased voltage caused the original 10uf 100v capacitor to fail, then replacing it with the 10uf 250v will permanently solve the problem. 75 cent FIY!

Posted on Jul 04, 2008

I word use the capacitors 10uf 250v in plast of 10uf 100v
cap in model 27pt6441/37 and #6442 and 2463
chassis l04.1u the phillips corporation put the roged cop in
they put 10uf 100v win it shod of ben 10uf 250v
that is way the 10uf 100v wend bad it was not schgeef for
the tv the cap is in the back by the flyback and the rca out and in put and the bord # is 2465
it fix my 4 lines on the top of the screen.

Posted on Jun 25, 2008

Soultion #2 worked I only relaced the the cap #2465 10u 100v electrolytic and the TV works fine now.

So I have a 50 Lg ( LG 50LN5700). There is still a picture however about every 3 seconds it goes from regular to blurry and repeats. There seem to be about 3 black lines across the top horizontally about 3...

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

Horiz. sharp line from 2 inch bottom

If the screen is part of your laptop/notebook/netbook, try to connect an external monitor to the VGA port, to see if the video-card in your computer is generating the "weirdness".

If the screen is an external monitor, try connecting it to a different computer, to see if the "weirdness" follows to the new computer,
implying that the monitor is faulty. Also, connect a diffferent monitor to your computer, to see if the video-card is causing the problem.

Blue tint and lines on screen.

Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
