Semp Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SEMP TOSHIBA | 32LH86 | Turns on, screen lights up but turns off in approximately 15 seconds | Chap. elect. CG06, CG07, CG14,CG15,CG20,CG22,CG24, CG35, all 10x50v and C629 and C685 1x50V on the main board and CE87 10x50V on the intermediate board | Testoni Junior | |
| SEMP TOSHIBA | XB1207 MU | Doesn't start | Check pin 7, if it is low (8v +/-) change c803, if tsound is no voltage change r805. | Carlossbs | |
| SEMP TOSHIBA | LC4046FDA | Without image, with sound. | I identified the open fuse f102 on the inverter board and a short to ground caused by some component on the right part of the board. By pure luck, the first component I removed for measurement was the one causing the problem. The smd 125v/7a fuse (f102) and the ci 4614b (q310) were replaced and everything worked again. | Bertinetti | |
| SEMP | 2134 SK11 | After changing the TSH, it got too hot, and on the screen tsound was an effect known as a cup, or cushion (this TV does not have the horizontal correction circuit made with the Q302 MOSFET, it is empty on the board) | Changed deflection coil. | Replace the deflector, (tec. edfersom, varjota-ce) | Edfesom |
| SEMP | 2134 SK11 | Power supply +b high going into protection and LED flashes intermittently | Resistor connected to pin 5 (adj) of strw6554a in the primary power supply. r609(36k) measuring 69k | Replace resistor r609. I had previously replaced the photocoupler - tl-431 - q606 - and nothing. Until I realized that the defect was in the primary power supply, which wouldn't go down at all. | DAVID LIMA |
| SEMP | 1483BAV U10 | No characters or tuning, blue screen | No tuning, no menu | Broken solder on the qb20 transistor that connected the rb20 diode, pin 1 of the vertical | NilPassos |
| SEMP TOSHIBA | TV14 VARIOS | No channel 3 and av i.e. blocked channels (when I tried to put them on they didn't appear, they were blocked) | Enter the menu (normal) and select the option, block av/tv (something like that), go to password and press "s" on the control several times, until it unlocks. | ||
| SEMP | TV2134BSL SK11 | Does not turn on, burning regulator strw6554a, | Change without measuring biteludo cap 220uf 400v | DJ PITUKA | |
| SEMP TOSHIBA | 2934 SK91 | It doesn't turn on, just the relay hits | TV hits the relay, LED stays off | -trazesto q604 -trazesto q606 capacitor c311 | glaydysom rio branco ac |
| SEMP TCL | 32S5300 RTK2841 | Does not activate, nor does the ST BY LED. fuse intact | Measures secondary power supply voltages zero.causes mosfet qr01 - 15t15gh shorted. - ref. 150volts, 11.2 a channel n. | OLIBIO - ELETRONICA ESTUDIER CANOAS RS | |
| SEMP TOSHIBA | 32L2400 40L2400 | Does not turn on, LED is off | No. 07 | Vdw904 measuring short, but it's the ci nw907's fault | Adrian (Chapadão do Céu Goiás) |
| SEMP | TV2922 | Jagged image | Dry or damaged electrolytic capacitor, CD11 10uf/160v | To replace | José Velk Marques |
| SEMP | 1450MAV U17 | The bay is blinking with a ticking noise when turning on | Q404 saída horizontal 1803dhi c440 5n13,5/1k6 | I put another one from a scrap bimba TV, it focused well again | Marqueis eltec eletrônico |
| SEMP | 2134 | Vertical TV closed at the top with thin stripes | Diode d 304 ba 158 replace | D 304 ba 158 | OP ELetrônica |
| SEMP | TV2922 (J) LEM10/FS8 | Low sound even at maximum volume | Capacitores c636, c637 | Replace of the same | ASSISTEC, MANARI/PE |
| SEMP | LC4246FDA | Backlight flickering. (flashing) | Poor contact in some high voltage transformers and lamp connectors! | Renew all solders on the high voltage circuit! | Adilson |
| SEMP | 32HL86 | Strong hiss, and lower audio on one of the channels | As for the hissing, it was the 1micro capacitor c629 with half the capacity and as for the lower volume, 10micro capacitors cg06 and cg07, both with very low capacity | Replace the mentioned capacitors | <small>This email address is being protected from spambots.
