Re: Blury lines in the picture / no picture / intermitent...
Is great you have already found the place to hit and get the picture back,is a loose conectiont that need resoldering before it gets worst or damages something,be ateentive were you hit and flip the crcuit board,the broken solder joints should be easy to spot.
If you are not too familiar with tv service seek the help of a servicer and tell them what you do to make it work,the repair should not be xpensive since you already diagnose the problem.Good luck

Possible that the CCD is a suspect. Try and allow the camera to be switched on for a long time, keep free from moisture or near a lamp to dry. If not best is to take a referral for consensus without tampering without proper jig, spares and tools.
Focus and Screen. The focus control may help, just like focusing a set of binoculars or an old camera. Watch the picture on the TV, using a mirror can help and make an adjustment until the picture is as clear as you can get it. If it still is not clear it may mean that your picture tube is weak. If you can avoid it, don't touch the Screen control. If you have, let me know and I can advise you on the proper way to adjust it.
In all probability the picture is fuzzy too, its just harder to notice. This can be as simple as an adjustment in the back of the set. Carefully remove the back and look for the flyback transformer (part with large red wire coming out of the top). The should be 1 or 2 controls on it. One should be marked focus. Adjust that to get sharper focus.
Good DAy, mitas;
It sounds that the TV is having a Convergence Circuit problem or you may CRT Coolant (fluid) on the PCB's. Good Luck, big IRISH........ PS Call for help, by calling a Factory Service Center....get an estimate!!
I have the same problem on my tv - the colors are seperated - the picture is blury and in converge mode the colors will not line up. Need to know if I need to go and buy a new flat screen tv. Any advise is appreciated. Thanks
picture blury problem is due to
1 focus wire loose or disconnected due to long life of connection.this wire is in crt base.
2 focus control mistunned.
3 low voltage on crt electodes.
4 if tv is old then crt is getting weak.
5 crt base or connector loose
hope this helps.
