Fascination arrived in the Repair Station alive but barely. The game turned on but
only produced a white screen. Nothing else happened and no sounds
could be heard.

I
thoroughly cleaned and tightened all connections, reseated the
PCB and powered the game up again. This time I was met with a
'stretched' picture
but a picture nonetheless! The picture
was stretched side to side and the paddles were either off the screen
or
shifted over thereby making game play impossible. I needed to
investigate
the TV to see if there was anything wrong with the chassis.

An obviously defective capacitor was found on the chassis of the
12" Hitachi TV. The model number for this particular TV is
P-021. I have never seen a capacitor where the dielectric
looks like it had exploded! Typically I have used
burn
marks or swelling as the calling signs for visually identifying a bad
capacitor. The rating was 220uf 16v and was
upgraded to 220uf 32v. Soldering on this circa 1973 chassis went
very well. Other cold and cracked solder joints were found and repaired.

When the TV was put back together I was met with a 'very
clear' screen of jumble. The good news upon seeing this was the
fact my fixes had indeed made a change in the display!

After tweaking all the adjustments on the
chassis I was met with a very sharp
picture! Not bad for a 35 year old TV! Bring on the
Pong tournament!
