SEMP Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TOSHIBA | ALGUNS MODELOS | Horizontal problem | To test the horizontal, release the base voltage of the transistor q830 by disconnecting the transistor q432 and make sure that 9 volts appears on the collector. This voltage feeds pin 17 of q501, generating a square wave on pin 13 that goes to the base of the horizontal drive transistor. | Miltom | |
| SEMP | TV2084FAV | Image with horizontal scratches, appears to be a vertical problem (shutter effect) | The defect was the s.h transformer. tfb4126 | Bruske | |
| SEMP | TV 2090-AV CHASSIS-U14 | Slow to oscillate | Replace capacitor -c887 100/35 | eletr.campo grande.jps | |
| SEMP | 2080E | Shorted power supply inoperative | (q804) shorted | Replace it and solved it only that the vertical one had lines of retractions at the top about 5 cm, the capacitor was replaced (c 325) | EVALDO GOMES ELETRÔNICA GOMES |
| SEMP TOSHIBA | TV1490 -I U14 | TV only has sound by holding bare volume buttons | Cold solder on the sound output and microma | Resolder | eletroclaudio aguas belas |
| SEMP | TV 2090HAV U13 | Doesn't work av | Rv02 and rv06 open | ÁdrianChapadãodoCéu | |
