Question about Philips 27PT6441 27" TV

1 Answer

Picture problem, top few inches.

Read in someone elses similar problem that this may be related to a bad Cap on the B+ line to the Vertical IC... does this sound correct? Here's a picture of the problem. The top of the screen is getting worse by the day. It started out just barely noticeable a week or two ago. And keeps growing wider. The top of the screen has rolled itself down onto the picture and inverted itself. Any suggestion would be helpfull. I have done some minor tv repair in the past, and I'm also a laptop computer specialist. I have skills in soldering and such, just need to know what to replace, I have no schematic on hand for this.

    Didn't find anything on that site... but did find the schematics elsewhere... only cost $19.95 for the pdf service manual, came with the details i needed.

    And also found out, that most likely it's due to bad capacitors in the vertical circuit. Going to just replace each one and be done with it.

    Yes, I have the same problem. Haven't yet been able to go at it because the wife doesn't want me to start and put it out of commission while I search for the problem. I have the manual if that might help someone. I could email appropriate section if desired.

Hi you can get a service manual which includes schematic from this site:    http://www.download.nitd.co.uk/news.php      you will have to register with them before you can download it, but this is free.   Plus you will probably you will have to download  another free program to (shareware) to decompress and read the rar. files  I used  the one for xpwindows:  http://downloads.zdnet.com/download.aspx?&docid=284618&promo=100510

No picture just on line in the middle left to right


I know the line is horizontal but the problem is in the "Vertical" circuit of the set that deflects the picture from the middle of the screen to the top and bottom.

Only a few easy possible reasons for this.

1) set has developed bad solder connections in the vertical output circuit--it happens as a normal thing and most sets like this the picture will have opened and closed before going to just a line.

2) a part in the vertical output circuit is bad---most common is a IC chip for output. Not real hard to get at or replace and is inexpensive.

If it is as stated here a 27 inch set it may not be economical to fix and cheaper to just consider replacing it.


Let me know if you have questions.

I have white horizontal lines about 2 inches at top of my tv


You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking.

Lines across my tv where the picture is reversed


You have bad capacitors in the vertical deflection. And you will have to resolder the vertical IC as well. Replace the caps in the area of the vertical IC. Find a TV tech or hobbiest to do this!

Horizonal picture 4 inches high across middle of screen


Hello jpm1lo, your problem needs someone with some repair skills to assist you, firstly your TV has both a horizontal and a vertical circuit,your problem is in the vertical circuit. The IC (integrated circuit) in the vertical area should be changed together with the 2 or 3 cylindrical capacitors ( number will vary in different brand names) also in the same circuit. This will rectify your problem.....Rudney

Single horizontal white line on screen


This is either bad connections at the vertical IC or a defective IC. This should be a small flat IC attached to a heat sink. It will be marked LA7837 or something similar. It will have about 11 pins. If you are not sure you have the correct one, post the marking here and I'll confirm.

The vertical output IC has stopped working. The vertical output IC is the part that drives the coils in the yoke that spreads the picture up and down. This could be because it has cracked loose from the board (solder joints) or it simply burned out. Sometimes a bad pump-up cap will cause the vertical output IC to short out, and when the IC shorts out it often opens up a small value resistor next to the flyback. This is a relatively easy thing to repair. A qualified tech will be able to tell exactly why the vertical output has stopped working and repair it for you.

Sony CRT Tv (KV-T29SZ8)


When you see white lines at the top of the screen, it means that the pump-up capacitor next to the vertical output IC is bad and the IC is about to quit. When the output finally quits, you get a black screen with possible dim spots. The vertical output IC and its pump-up cap will have to be replaced, and the little fuse resistors next to the flyback in the + and - supplies to the vertical output IC must be checked too. If you have experience working on TV's then you can do it yourself, but if not then have the set serviced by a tech experienced in Sony sets.
