Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP | 2134(B)SL | Image closed on the sides | C635, c636, c309 and also check c325 | Marcones de araripina PE. | |
| SEMP | TV2134CSL SK11 | Sound in normal av, in rf distorted hoarse sound | Replace r805 | djpituka | |
| SEMP | TV 2134 (C)SL SK11 | Turns on and off quickly, hitting relay | Changed resistors r309 and r308 and burned vertical output ic301 | Replace r309 and r308 (the two 0.33Ω resistors), replace ic 301 (utc78045) | Bruno - Minas Fax |
| SEMP | LC 3245 W | Pfc goes up and I fall... | Capacitor 150 uf x 450 v.... exhausted, zero capacity | After reviewing the PFC resistor loops,...the capacitor was left....resolved. | GGN |
| SEMP | DL3245L | Does not turn on.. standby on without turning off or lighting up | 3.3v 805 resistor giving 1.5v processor line | Replace it and go for the hug | TecSat são Leopoldo |
| SEMP TOSHIBA | DL3244 | No image, backlight on | Cd25 and q3 shorted. | Capacitor is 10μF and q3 is a pnp transistor, not a fet. If you put fet channel p it works, but t-con is noisy. | André |
| SEMP TOSHIBA | TS2018 | I don't know | Nick | ||
| SEMP TOSHIBA | LC3255 | Cuts digital tuning or does not enter digital channels intermittent | Cold soldering on smd n100 integrated circuit | Resolder the ci apply soldering flux use a blower be careful insulate the capacitors around them so they don't come loose | PAULO PINHO |
| SEMP | L32S4900S | No image | Tcom fuse and polyester capacitor c49 just remove | reginaldo moronte,eletronica junior caldas novas | |
| SEMP | 43S5300 | Scratches on the screen, display defect | Display defect | After several attempts to eliminate lines on the flat on the right side, I managed to greatly alleviate the defect (tsound were still some lines left (barely visible)), on the right flat on the right side I left 2 contacts free and covered the next 3 contacts with tape. | Claudio Jorge Eckert Junior |
| SEMP TOSHIBA | DL3245(A) | Sometimes it doesn't turn on, or keeps turning off. returning to standby | N805, 3v3 regulator giving 2.8volts, close to the processor | Eletrônica Cecé. Brumadinho MG | |
| SEMP TOSHIBA | 32L2600 | Burning leds | Remove 2 resistors and leave without r634 and r633. reducing the voltage going to the LED bars. | LOGANKLEITON | |
| SEMP | 2123 (0) U19 | It didn't give anything | It was a street 5453 | Resolved | Antonio |
| SEMP | LE4057L(C) | Backlight does not turn on | Defect in chip n701 (ocp8122a) that releases the pulse for transistor v9 and v10 that controls brightness | Just replace the n701 chip (ocp8122a) | ELETROSANTOS |
| SEMP | LC3246WDA | TV without image, with sound, lamps on. | Short vcom card. | Shorted smd capacitor cd39, close to memory ux1. | RNSPTEC |
| SEMP | LC3245W | Yellow LED and does not turn on | Short smd capacitor on signal board | Capacitor c821 shorted, you can see that ci n802 heats up a lot | Ariel Santos |
| SEMP | TV2123 (0)FS U19 | It takes a long time to turn on or only turns on when it heats up. | Capacitor seco, c423 ( 10uf / 50v ). | Replace it for a new one. | NATO ELETRÔNICA |
| SEMP | TV2123 (0)FS U19 | It takes a long time to turn on or only turns on when it heats up. | Capacitor seco, c423 ( 10uf / 50v ). | Replace it for a new one. | NATO ELETRÔNICA |
| STI SEMP TOSHIBA | LE3256(B)W | TV turned on, display doesn't work (works for a short time) and blacklight works normally. | Transistor v818 model 3904 npn of the vcc-panel block short circuited, preventing the mosfet n805 model 9435a from receiving a voltage lower than 12v from the gaite and thus activating the 12v voltage for the t-com board (responsible for turning on the display). | 1st test: test the t-con input voltage, (vin=12v) 2nd test: test the voltage on the drain of the n805 mosfet (d=12v)[9435a] 3rd test: measure voltage at the power supply and gate from mosfet n805 (s=12v, g | Jonas Saraiva |
| SEMP TOSHIBA | LC3258WDA | Turns on red LED and doesn't turn on TV | Ok power supply supplying 3.3v and main board does not activate. | 10k smd resistor r156 is open. | Alessandro Barcelos |
