| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| RCA | F35670MB CTC187CN3 | Dead. f4001 5 amp fuse open | Check u4101 stk730-150 part no. 223948, check cr4106 for short, check q4401 for short, replace all shorted or open parts, check the two main filter caps on the secondary off of smps, replace vented caps, replace 10uf 200v cap off of reg. | ||
| RCA | F35670MB CTC187CN3 | Common problem bulletin: | Resolder all ground connections in and around, and under the tuner shields, solves most problems, prevents big problems as in dead eeprom or cpu | ||
| RCA | CTC177AF3 | Overloaded picture, agc not adjustable | Found ic7301 cxa1594 bad. replace ic and align tuner parameters | ||
| RCA | F27442 CTC203AD5 | No power, all standby voltages ok | Replace the guide plus. is located to the side of the tuner | ||
| RCA | F19220BK CTC175L2 | Erratic screen / intermittent, eprom causes multiple possible symptoms, clicks on/off, tuner, you name it ! | Mass defect caused by bad solder in tuner, once fixed will probably last forever. resolder tuner wrap-around groundings and all pins under tuner shield bottom, if no success suspect a corrupted eprom | ||
