Question about Philips 27PT5445 27" TV

1 Answer

Mkgregory I have a Philips 27PT5445/37 television with a vertical linearity problem. The picture is cut off on the top. I have changed or checked all of the electrolytic capacitors and resistors in the vertical circuit. There is no adjustment for linearity. There is an adjustment for vertical height.

    i HAVE THE SAME PROBLEM...SET IS ONLY SLIGHTLY OVER 2 YEARS OLD AND OUT OF WARRANTY...

  • walkermg Feb 28, 2009

    I had 2 of these same models and the first one that I used the most did this (losing the top of the screen) after about a year of use. Now the other one is doing it after about 1.5 years of use.

    I threw the other one out, but I have not gone digital yet and want to keep this tv because I can no longer buy a analog tv anymore.

    This must be a common problem and was looking for the quick fix (adjustment) for it

If the TV supports it, you can go into service mode by press ing the following on the remote control:

062596 i

This will take you into a service menu. It also changes channel as you press the keys, so change to a used channel to get a picture back.

I am not familiar with this model, but the principles should be the same.

Using the remote control to navigate the menu, you are looking for "allignments", and from there "Vertical Amplitude" or V/AMP or VA or similar.

BE CAREFUL when making adjustments, as you can permanently damage the TV if you adjust any critical settings.

When making changes, make a note of the original setting so you can put it back if its not the right option. Also only make changes 1 notch at a time. It will be obvious when you have the correct option, so if nothing is happening after 2 or 3 notches, then put it back. This will minimise risk to the TV.

When you have finished, look for a "Save settings" option, if not just press standby to get out of the service menu.

It is a vertical deflection circuit fault. Vertical non-linearity. Replace all the electrolytic capacitors used at vertical scan output section circuit. There will be 5 or 6 of it. Replace all at one time. Be sure to replace all of it with same capacitance value used. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

If the problem is with its picture linearity [Vertical], you have to enter its service mode to correct it. It is best to replace all the electrolytic capacitors [5 or 6] of it, at the vertical scan output circuit, before doing any adjustments, because, if there is any of it is damaged, the fault to this kind can occur too. After replacing it, just switch ON the set, and check the picture linearity is correct. If not, enter its service mode, and adjust the vertical picture linearity.

You have to get in to its Service Mode option to change the data values of height and linearity adjustment. Visit the site named 'Electro-help' for more details. Check this link and select the site named above. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy. Some times, the ads attached with each posts might help you to find the availability of spare parts. There are more than 580 posts to different brand TVs.

Sanyo AVM-20F5 vertical non linear


Check and replace all the electrolytic capacitors at the vertical output section circuit. There will be 5 or 6 of them. Replace all at same time. If it do not help you, you have to enter its service mode option to adjust the vertical leanearity of the picture. It is a skilled job. The service mode window is entirely different to that of Menu window. You must have through knowledge in electronics to follow. Improper adjustment to this window might make TV irrepairable.

Not sure which philips i have, but suddenly lines have appeared at the top of the picture, going the width of the screen, about 4 inches down the screen, and moving downward.


It seems you may have a vertical linearity problem. Check all electrolytic capacitors around the frame output stage. The frame output ic may be at fault but this is less likely.

Vertical line at edge of AV1 channel


hi! he might have adjusted the vertical hold and height including the linearity. normally on the board you would see a trimmer resistor with a label v-hold this is to stop the rolling, v- height for the size of the picture. and linearity for the evenness of the picture from top to bottom.

Picture is cut off at top and bottom


Hello This is an indication that your vertical output stage is beginning to malfunction. It could be the vertical output IC or the vertical coupling capacitor. I would suggest using the schematic and an oscilloscope to determine if the signal is correct. You may have to replace the IC or the capacitor.

I hope this helps,

Thank you,

Problems with my screen/picture


Sounds like a vertical sweep problem in the vertical output circuit, or the drive circuit. this is a solid state set and there are no user replaceable parts inside. Please play it safe and take the set in for service. Good Luck
