Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:
If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.
If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.
If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.
A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.
Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!
Hello. It looks like problem is originated near buffer board/s. You can try to repair this but it is not recommended for untrained person. If you remove back cover of your TV on the left hand side you will find ribbon cables that connected to narrow and long buffer board (or two boards) with one end while other end goes inside PDP (Plasma Display Panel). Poor connection could be present on any side of that ribbon cables. You can try to "play" with ones that are visible and see if it will clear the picture while TV is turned on. But this is not safe, there is about 200V running on some boards so you have to be extremely careful. If poor connection is on the other side of the cable - than issue is impossible to fix without replacing whole panel. And this is more expensive than just buy a new TV. I would recommend let professional to take a look at it. Your health and life is not worth of any TV set out there. regards. Russ.
it sounds like one of your buffer boards are going bad. these are the boards that help put the picture on the screen. there are 2 boards an upper and a lower board. if you remove one and turn the tv on you will get half a screen. see then if you get the lines. please leave rating after you check.
Red picture tube needs screen voltage adjust. Open fornt or back of TV and look for a black square looking box with adjustment knobs. Look for red screen adj and slowly turn rt or lft until lines just disappear. If screen goes too bright tv will shut down, just turn back on again and retry
if TV have black screen,increase screen control to see vert amp IC is defective if you see one horizontal line in picture tube screen,and if screen is white with lots of line acrose ,you can find open resister,on picture tube board,or in main board near HV transformer.
It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
