Re: blurred pic on tv
You can take the back off find your flyback (the big part with a red or pink wire going to the picture tube) and adjust the small pot or potentiometer closest to the top while the set is on in front of a mirror and try adusting the focus control.
if cant get nothing but blur replace the fly or focus assembly if not built in the fly. I would change both.

it sounds like the display may have finally gone out, however i would recommend to check other inputs (AV1, AV2, etc) by connecting a dvd player or game console. it may just be the one input that you have your cable box or coax cable connected to, so testing the other inputs will help determine this. if you get the situation with all inputs, no video but sound works, then you will either need to have your tv repaired or replaced.
You need service. Sounds like the convergence is out of adjustment. As the picture is formed by a tri- gun arrangement (one for each colour), if any of them is not correctly aligned, you will see shadows on any sharp line like text, or blurring on a picture. The shadow or blurring will often be one colour i e. red, blue or green.
My Dad had a Hitachi rear projection with same problem blue and red were fine green was out of allignment and could not fix. Problem was the acual projector inside TV the cost for repair was more than TV was worth went out bought plasma.
If you know all the saftey aspects about tv repair then your gonna need some special test equipment to troubleshoot this set. There are no real user serviceablew parts inside this tv as they are all soldered in and you cant tell by looking at them if they are bad. Theres lots of hi voltage inside these sets even afterv they are unplugged for awhile. if you know all the saftey issues your gonna have to first disconnect the horizontal output transistor and measure it with a good ohm meter. If it measures bad ythen order a hi voltage transformer and replace both at once. If you dont have this equipment or know how to unsolder and solder then you should call in a pro to assist you with this repair. Good Luck
the resistor overheated as a result of the diode or the capacitor went bad. Your gonna need to get a schematic diagram and find out what the part #s are as you cant just put in any type of diode capacitor or resistor. Also see what thay voltage source feeds and make sure nothing else is shorted.. Good Luck
