Blurred picture on TV Screen. I bought my Sony TV about 13 years back. The picture on my TV Screen has become blurred. What can be the problem? The focussing slightly improves after I run the TV for few hours, but not satisfactorily. I have tried to improve the focussing by adjusting the POT behind the CTR Base but to no avail. Will changing the CRT Base help?

suggest you sell it off if you manage to find a buyer that is.. get a new one mate..
