[TechAssist] Sharp TV, 25HS80, Fix

This set was supposedly hit by lightning.  Was dead.  Found shorted HOT,
Q602/2SD1556, hole blown in vertical output IC501/TA8403K, shorted diode
D502, (replaced with NTE552), and open resistor R510, 1ohm, 1 watt.  R510
was blown up and I didn't know the value.  I tried a .47 ohm--had too
much vertical height.  Spent too much time trying to find other faults
until I looked up R510 on the Tritronics website.  What a help!  The
correct value (1 ohm) finished the fix.
