Well budy, welcome to the real world of problem after problem even though you were there other problem start, Ah what in
H%$# did I become a tech.
First did you replace the stk with cheap china part's,
second have you check the vcc at the input of the chip, +/- about 25 volt.
The redish problem is adjudtment to the tint, here how you adjust this take colour off, then adjust screen to 80% and brighness to 40% and adjusting the screen control slowly to get perfect black and white without getting drive line. YOU Don't want drive line this is over driving the grides on the crt's this is located in the front of the screen a box about 4" x 4" x 1" deep and has about 9 wires that goes to it.
Now have you tampered with the aligment of the crt's nut screw well don't I Mean Don't.This is Focus only if you need it.
Next go to the menue (Service Menu) and do the aligment beleave me it's not easy and it will P%$# you off this is on page 46 http://servicemanuals.panasonic.ca/viewing/NA/PT-47WX52F/SVC/47wx_01.pdf.
Here is the schematic hope it help's http://servicemanuals.panasonic.ca/viewing/NA/PT-53TW53G/SIMP/PVAccel.html

Check the micro/pico fuses as well found around the same area where the resistors and STK ICs are.
