My screen shows lines were I swipe

A factory reset might not fix this, but here you go.

Hard reset by removing the battery while the device is on. Restart. If the touchscreen still doesn't respond then you have a damaged screen or digitizer. Visit a trained technician to fix this problem if it persists.

If your iPad otherwise works normally (i.e. the touchscreen is fine), this was probably an input problem. I've found that my fingers don't work well on touchscreen devices if they're cold, or if my skin is dry. That usually means I tap or swipe things and it either doesn't happen, or doesn't quite work right because it couldn't track my finger properly.
Another thing to be careful of is that you purely tap the screen, and don't let your finger 'wander' on the glass before you lift it away. The iPad is very sensitive about skin moving on the surface, and if you're not very deliberate, it'll treat a clumsy tap as a 'slight swipe' - and swiping doesn't bring up the keyboard/cursor, so it appears not to work.

Its bootsector is lost due to some viruses or due to any accidental sudden sutdown.Try reinstalling the firmware is the solution

On my Panasonic PT-56TW53, the down left quarter of the screen has a big colour distorsion. Convergence can adjust blue and red, but green is not able to show a straight line. Is tis a mechanical adjstment? Help would be great.

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

it needs caliberating which can be done by going into the setting

that is wot most do. Lol Tamsinx

Sounds like, you have a bad optical block. Part can cost $550 to $800 + labor

Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket
