Re: horizontal blue line in centre with black back...
This fault sounds like a frame colllapse. The supply voltage to the frame IC may have gone open circuit or the frame IC itself has gone faulty. Unless you are experienced with electronic repairs I strongly suggest you are best to take it to a repair centre.

Please pull front speaker grill and find focus block, fixed at corner having 6 control knobs on it. Find Blue Screen control knob there. Put your TV in AV mode to get dark screen and just press Display button on remote to have AV display. Now
slightly rotate control knobs counter clock wise until thin lines
(retrace) disappear. Job is done and put back speaker grill, press
display button again to disappear screen display.
Hello, You need to adjust (actually bit decrease) G2 volts (calls Screen volts) of Blue gun. If you are familiar with big TV repair and have electronics knowledge then let me know to guide you further. thank you.
Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.
horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,
whenever you see horizontal line please reduce brightness of your tv for safety of crt.
your problem in vertical section only mostly due to loose contact in
connector,print or loose components.
