CTC177 trouble!!
You guys are missing the info!! These units will not run
with high standby B+. Scopes & EEPROM changes won't fix it. I tried everything I could think of. Just read again. Rono. RCA 25" M # 25GT536, chassis # CTC177AG. Unit was dead, replaced STK-730-010 (shorted), R104 1.5 meg ohm (gone high), C4105 10UF @ 250 Volt (gone leaky), checked/replaced CR4108 (130 volt line), changed C4402 (warped), 12 volts, & 5 volts standby is fine, 5 volts to EEPROM, & tact switches, but 130 volt line is +146 volts dc. B+ to LA7610 main jungle IC +7 volts. B+ to horizontal output, & drive is + 146 volts, & unit won't start. What did I miss? Rono. |
