It seems like the top in folded or smashed and is brighter than the rest of the set. I looked for obviuos damage to the components and didn't see anything. It seems to get better and worse throughout the day. Any help would be greatly appreciated. I do work in electronics but never with TVs.

SOURCE: Philips 27p6441/37 has a foldover
Bad capacitor / IC in vertical circuit...usually a shop repair...
If not corrected,could get worse in short period of time,.....T.
This model also requires an upgrade kit for future reliability...

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.

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,
