| SEMP | TV 2177 | Alloy with dark screen and retrace lines on the side. Note when it heats up it starts normally. | Capacitor c416 10uf 250v exhausted or without capacitance near the driver transformer. | After changing the TV ok. | George Pontes |
| SEMP | TV1454PSL KD-321 | Turns on and off with lines on the screen, shaking | Change cap c512,681 near the power supply regulator | DJ PITUKA | |
| SEMP | TV2159 OFS U19 | RF channel does not enter, the drizzle does not appear, half-black screen with no RF signal | Replace zener diode d412, 10v not secondary power supply | DJ PITUKA | |
| SEMP | TV2977ASL LEM10 | Does not turn on, the standby LED turns on and off and does not turn on, 170v power supply, normal 130v | Replace diodo zener d861 ,15v | DJ PITUKA | |
| SEMP TOSHIBA | DL3244 | Backlight turns on and tsound is no image | CD25 shorted on tcon board | Replace cd25 tcon board if you can't find it, put 10μF 25v electrolytic capacitor | beto2828 |
| SEMP | TV1451 NAV U18 | Greenish image | R915 smd tube plate | Replace it for another like it | ELETRONICA CAVALCANTE EM MARTINOPOLE CEARA |
| SEMP | TV2051 NAV U18 | Intermittent image normal sound I thought it was cold welding | R413 | Replace it for another like it | ELETRONICA CAVALCANTE EM MARTINOPOLE CEARA |
