Hey Larry,
Check the condition of I584 the 9 volt regulator IC. Regulator develops
ring fractures around pins Of I584.

Hi Guys, went out on this set last friday and installed 3 stk4274`s for
typical convergence failure, found no bad/burnt
resistors so I replaced stk`s set came up perfectly didn`t even have to
touch the "magic focus", customer just called
and said set is now getting very bright, shakes, and has colored retrace
lines from top to bottom, shuts off set for
several hours and set will come on with perfect picture for 5 minutes
and then repeat the problem, going back out
late this afternoon to check it and it`s a 25 mile one way trip, any
ideas ? Larry E
