Question about Philips 27PT5445 27" TV
Since a recent move, our Philips television has not been working the same. It did not get bumped around or anything of the sort. The picture is cutting off at the top of the screen. There is about an inch and a half blank and blurred space at the top. We have tried to adjust the width of the picture with our remote and it made no difference to the top of the screen. If anyone has any ideas or solutions, please let me know!! Thank you.
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

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox,
Sony, Panasonic, and others were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional $$$$$$$??????? (Is it
2. Open your TV and find PSB. (The board that the power cord
plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps
replace the entire board. The entire
board costs around $250 right now because they are in high demand right now. They
can be found at tv-part.com but supplies are limited. I would definitely shop around though.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing
the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help
guide people though the process as well.
Let me know if I can do anything to help.
Hope this helps and Good luck.
