Atari 2600

TECH TIP #10
R-220
Check that R220
is properly soldered.
If they aren't,
they
will cause
intermittent gray bar problems.
TECH TIP
#Ill
Solder Check
Check solder on the following components:
C210, C211,
C203, C220, C212,
C208, and C209. Long miscues on these caps prevented them from being
soldered properly, causing intermittent problems on the board.
TECH TIP #12
Hex Buffers
The 4050 (A203) on the 2600 should
be one of the first things checked for
any of the following problems:
any trigger problem, no Sync., lose of
lum lines. This is the
reason
for a high percentage of returns.
TECH TIP ill3
5201 and
JlOl on the 2600
Both of these connectors should be checked for
a good, secure fit.
TECH TIP #14
Crooked Switches
Inspect switches on 2600 switchboard to insure that they set flat
and
perpendicular to the board. Reset all switches which are not.
