Re: Looks like pen marks on inside of screen

What you are decsribing sounds like your picture tube or tubes have been scored (permanent burn marks on the picture tube phosphor). The sure way to tell is to remove the front screen and look into each of the three lenses while the set is on. You will see a black image of your pen mark within the picture. Did you recently have problems with convergence or the set shutting down (turing off by itself for no resaon) ?

The tv has red images, I cannot get the red convergence line vertically to straighten, it is squiggly, the horizontal is straight, and the blue and green lines are both okay

the 43h71 has a pair of convergence ics that commonly go bad and cause this problem. replace original stk392-110 with stk392-120. the upgrades have a collector rated at 4 amps vs the 110's 3 amps and should be more reliable.

also know that they hyperboard in this set can cause squiggly lines throughout but will not affect the convergence.

Green convergence on Panasonic PT-53WX42 is not ligning up...

Does not sound like the chips are bad.
What you need to adjust is "SKEW". You need to enter "service Mode" then go into "Coarse Convergence". Skew can be adjusted for all 3 colors. Unless you have the service manual, these corrections should not be attempted.

To clean the INSIDE of the screen, you really have to disassemble the TV. Remove all the screws that hold the "back" ( the piece with the mirror) to the front (screen) assembly.
The screen can be cleaned with a solution of diluted isopropyl alcohol, no more than a 50% solution. Drugstores will carry it, but it might be 70%-90%. Just dilute with distilled water (not tap water as it contains minerals). Personally I have used 70% with no ill side effects but 50% is recommended.

Squiggly Lines at Power On

Generally speaking, this type of symptom is caused by AC hum leaking throught the power supply. This can be due to a bad filter cap. Since this clears up after a while, I'd start by looking for poor solder connections in the power supply area. If you can, check the caps in that area as well. I'll research this a bit and try to get you more details.
