| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | BN44-00260C | Dead | Check and change d801s, qi830,qi832 and 4ah 250v fuse | Kaya Elektronic09 | |
| SAMSUNG | MXC850/XAZ | Only has sound in headphones | Ica1 on the power supply that feeds the 45 volts | Just replace ica1 and run for the hug | jefferson |
| SAMSUNG | PL51E450A1GXZD | Image flashes intermittently normal audio | Checking all TV voltages were normal defect control board replaced resolved | Paulo Pinho | |
| SAMSUNG | UN32D5500 | Dark image or dark backlight | C9121 at power supply | Replace the polyester capacitor position c9121. After this, the TV returned with normal screen lighting. | Charles Viante |
| SAMSUNG | UN46D5500 | HDMI doesn't work and when it turns on the following message appears: please go into service mode and setup below options.-type´local set´front color option | Enter service mode and change parameters | sergio | |
| SAMSUNG | LN32E420E2G | Image folded after a minute | Display | With the TV without the cabinet and facing upwards. He rips the flat from left to right until it's perfect. In my case I had to remove fifteen rails. it was left without a single risk. As I didn't find anything similar, I decided to help those in need. good luck. | OZATEC ELETRONICA SARANDI / PR |
| SAMSUNG | LN40A330J1 | Does not turn on, STBY LED off, no 5v1 | Zm802 zener diode shorted or leaky (it cannot have any leakage) | Have you already killed yourself measuring smds, replaced the um801s ic, replaced all the capacitors and nothing? replace the zener that goes up, if less than 5v goes up on pin 3 of the cn801 then check the entire 5v line and replace the couplers. good luck! | Snegs Eletrônica |
| SAMSUNG | LN40B550K1V BN44-00264A | Does not turn on or turn on standby | Verrificar q1820 q1821 (5n50ut), ci um8015 st strw 6252 e fusivel 8025 de 3,15a | sergiopax | |
| SAMSUNG | UN40J5200AG | TV doesn't turn on at all | Without 13v at the power supply output | Measure the three diodes at the 13v output. dm8610, dm8620 and dm8630, one of them will have a short circuit and just replace it | Brenner |
| SAMSUNG | P2470HN LS24EMSKUMZD | Turns on but does not light up the lamps that illuminate the screen but the sound and image are very dark | Trafo-inverter t301 -tm-08190 and q201-stu312d or 4506geh: after changing the frafo-inverter, when switching to a PC it 'turns off the screen' | Put 100k r from pin 1 to 6 and 7 of the u201-lem2005 | JCampos eletronica |
| SAMSUNG | HT-F4504ZD | Doesn't start | Blown fuse and mosfet 10n65a | Replacing them (note I put the p9n65zf mosfet) | zeluiz |
| SAMSUNG | CL21C650ML | Turns on with the screen full of retrace lines without key commands | Dz209 | Replace the 9.1v dz209 | Sinailson furtado |
| SAMSUNG | PL43F4900 | It doesn't turn on, when it turns on, voltages vs and va appear and it goes into protection. | After separately checking the power supply without the main board, using a 100r resistor from the ps_on pin to ground and 3k3 of the stdby voltage (5.2v) to the so vs_on pin, all voltages appeared normal. Even without the main board, I tested it by connecting the y and zsus boards, the vs and va voltages remained unstable, all that was left to do was check the main board, I turned off the bluetooth module and the TV turned on without showing any irregularities. | Replace the wibt40a bluetooth module. | edumiguez |
| SAMSUNG | UN40H5303AG | Image disappears after a few minutes | I looked at the LED indication | Replace dcdc converter | Warley cesar |
| SAMSUNG | CL29Z43MQ | I'm sound | Remove the q602 smd transistor, next to the sound output. | Remove the q602 smd transistor, next to the sound output. | DJ PITUKA |
| SAMSUNG | UN32D5800 | Stand by LED blinks until it stops and does not turn on the TV. | Smd transistor ic205 in the main, heating up a lot, due to the shorted capacitor c1020. | Replace of c1020. | Online Eletrônica |
| SAMSUNG | UN40F6400 | Sometimes it turns on and works, sometimes it doesn't turn on, the LED flashes 2 times quickly and the power supply relay keeps hitting, but it doesn't light up the screen or work, it stays in this cycle indefinitely. | I tested the power supply, I tested the LEDs, I tested the main board and I tested the tcon, I forgot about the joystick/bluetooth/wifi module. | The defect was in the bluetooth module, just changing it solved it... | MIGUELTV |
| 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 |
| 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 |
