H-BUSTER | HBTV-32D01HD | Does not turn on the back light, when turned on the lamps blink weakly and go out. | C-306a 220nf/305v and c-306b 220nf/305v with low capacitance. | py1acb | |
PHILIPS | FWM2200X/78 | Low clicks in the boxes, | Change 50v 1000uf capacitor, close to the box connectors | Ronaldo bylu | |
CENTURY | BR2014 | No audio and video, just drizzle or blue screen. | Shorted capacitor, CV45 of 1000uf 16v. | After changing the receiver ok. | George Pontes |
SEMP | TV2122 | Purple screen | Smd resistor r915 on the kinescope board. | Replace and come from currency. | DIGITAL SYSTEM |
ORBISAT | S2200 DIGITAL PLUS | Does not turn on, display lights up and keeps oscillating and setting protection. power command works. LED on and flashing | Voltage of +b 3.3vdc low (at 2.54 to 2.78vdc) causing a false "warning" of overvoltage to the primary power supply oscillator ci, causing it to switch less to reduce the voltage in the secondary... defect in the reference adjustment to the ci oscillator. | Replace: ( u8 ) - fotoacoplador 817 / ( u9 ) tl431 / ( c22 ) - capacitor 22μf/50v | Jhefferson Jung |
LG | 60PX950 EAX63347201(3) | Apparently normal league with no image (no video) | Change main board, preferably new or used, tested | Tip 02 processor raballing | Maike SR |
PHILCO | PH19C LCD | Red led | D002 open, flashing | Replace both diodes as a precaution | OLIMPIO- WATEK |
PHILIPS | 42PFL3604 | Doesn't start | No standby voltage, LED off, no signal | Check the primary coil (in my case it was broken), replace the 4.7μF x 450 v capacitor, it was swollen. After replacement it started working again! | Augusto Azeredo |
SAMSUNG | LN26D450G1G | TV turns on when it heats up, turns off sometimes turns on again, then turns off again | Ci 205 3.3v regulator changed ref: 1117z | I just replaced it and the problem was solved | beto_eletrotec |
H-BUSTER | HBTV-32D05HD | Turn on, turn on the lights and turn off | D18,d21,d20 and d22, in the secondary of t8 - w1 smd diodes | Eletrônica do Alemão | |
SAMSUNG | UN40H4203 | Turns on and after a few seconds turns off, all normal voltages at the power supply | Shorted main board | Replace the main board or remove the ps on/off pin and turn the LEDs back on | INFOHELP Arauá-SE |
SAMSUNG | 50C430A1M | It doesn't turn on, the relay at the power supply keeps knocking. | Shorted main board | After checking and noticing that the power supply and all voltages were normal, I discarded the power supply, then I scanned the zsus and ysus boards and noticed that both boards had their transistors and were in perfect condition. I isolated the main board and it was found that the short came from it. This type of TV is not advisable for laypeople to attempt to repair, as they have high voltages on the boards and are dangerous. but my problem was resolved and delivered to the satisfied customer. | ELETRÔNICA ALLFATV |
VISIONTEC | VT1000 SMART | Turns on and off by itself several times | Micro key | Replace microchave | Jr |
PHILCO | PH32U20DSWG | The original board was scorched caused by lightning, I bought a board and it had the following defect after the change, the TV turns off after 40 and 50 seconds | Software corrupted or incompatible with the screen, in this case I solved the problem by removing the memory from the old board and putting it in the new one. | Try updating the TV with original firmware, if the problem persists even after updating, remove the memory from the old board and place it on the new board. | Eletronica ALLFATV |
PHILIPS | 32PFL5607D/78 | It doesn't turn on, it just stays on standby, the LED lights up white and goes to red | Normal power supply voltages, grounded stand by pin, black light comes on and generates all voltages | I did a reset, holding volume + and the arrow key (input) while plugging it into the socket, it worked normally after that. | ser-mga |
