After moving my tv across town with a few bumps here and there the picture quality is bad to say the least.
When I plug it it w/o any type of inout the screen has a black background with 2" wide diagonal lines going across. If I use some sort of input, playstation or dvd, the colors are horrible and the pictureis very shaky and it seems as thought it is shifting up and down. After a while 20-40 minutes the picture seems to stablize to where you can actully get a sense of the image. It will still shake and give some distortion at frequent random times and the colr seems to be off to almost like a very old tv.
Any ideas? Maybe I can go in and adjust the convergence or look for disconnects? Replace some type of board? Use a multimeter to determine if there is something wrong?

The color wheel is your suspect.......usually whines a bit
when bad. In a quiet room, you can hear it when the TV is powered on or off. It spins at 9,000 rpm ( wears out the bearing).
The lamp will not exhibit those symptoms....
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!
I would just about put money on it saying it is your convergence board you can get it from the part store in any town for 50 $ (give or take) I had the same problem and that was the fix.
When I try to turn the tv on, the green light flashes and eventually goes back to red. A very faint picture came across the tv a few times but didn't stay. The tv is only 3.5 years old.
