Elenberg 29D77. Chassis A5N110-02. Ingredients: BP STR-F6456, 5115-064201-31 (TPI), a career exit TA8427K, video
NN5198K, TDQ-3B9/126CWA - tuner controller S3C8849X26-AQB9 SKY-5N11-00, ROM
24C02, C5148, D2803 correction.
Increased the size of the horizontal, laterally raster
pincushion distortion. Typical fault. The problem arose because under
the scheme is not a part of the S331, which caused difficulties. Scheme without
any corrections applied.
Stroke Repair: Tension in the RR + B 130 to. Overheating of parts no
correction. Tube heater voltage to a strict standard, so the upper arm of the
modulator and the collector of the HOT are OK. (HOT collector circuit faults
often lead to a change in voltage Heater). Before unreliable S329 4,7 mF * 50v
hard to reach the conclusions it hidden under a plastic chassis. Check ESR
meter showed the capacity loss of non-polar S329 4,7 mF * 50v, he changed to
K73-17 * 4.7 uF 63V.
The scheme as amended is attached, marked with a red patch.
