SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | PN43H4000AG | TV does not turn on or come on stand by, | Stand by voltage giving 1.2 volts | Resolder all the components on the power supply board including the SMD ones and, as a precaution, replace the photo couplers since Samsung has had problems with photo couplers. | Eletrônica Santista |
| SAMSUNG | LN32D450 | No image | V-com sem os 16v | After changing the cm501 twice in vain, I decided to replace the 6r8 inductor and the corresponding rectifier, the image came back immediately. | davi.sls |
| SAMSUNG | CL21Z50MQ | I'm sound | Zd605 shorted, 5.6v is close to the sound output | Replace | |
| SAMSUNG | LN40C550J1M | It doesn't turn on, the standby LED stays on and controls are stuck, sometimes it turns on and works for a while and restarts or turns off and gets stuck again. | The defect is on the main board wsound tsound was an intermittent defect in IC 203 that did not generate 5v. | Substituir o ic 203 na pci principal - (z1031) | Eletrônica Video Color |
| SAMSUNG | CL-21A551ML | Cup effect | In my case it was r411 | José Dias | |
| SAMSUNG | CL21Z39MQ 0000 | Turn on and off | Vertical output ci ic301 burnt la78045 | Replace ci la78045, capacitor 410 and resistor 414 | Paulo Sérgio Nunes de Araújo |
| SAMSUNG | UM 46EH6030GXZD | TV with blakligt on with sound without image | Smd co32 capacitor shorted on the tcom at the flets output to the screen on the right side | I put another smd capacitor and it was perfect | Ademar |
| SAMSUNG | UN46EH6030G | TV with blakligt on with sound without image | Smd co32 capacitor at the flets output to the screen | Ademar | |
| SAMSUNG | CL21Z58MQ | Doesn't start. LED takes time to turn on and sometimes the LED doesn't even turn on. | High power supply. reaches 160v. | After racking my brains and changing the tl431, photo coupler and testing a bunch of resistors... I found the c846 (100x25v) with low capacitance. reaching 91 micro farad. replace and run for the hug. | Eletrônica R-Tec |
| SAMSUNG | PN43H4000AG | Standby LED on, TV won't turn on | It says b5v due to a short on the line diode d202 on the main board shorted, replace the TV and it works normally again | Junior | |
| SAMSUNG | PN43H4900 | Does not turn on, LED blinks 2 times | Short on board y, q5029(igbt 30j127), q5018(pgd4536) and d5030(sf10a400) all shorted. | Replacing these components, the TV turned on normally, all voltages were ok, however some pigments were observed on the screen in the left corner and also in the center, indicating a problem with the vcscan circuit, I found the q5008 sun0550 was leaking, I replaced it with a 5n50 mosfet, it worked again normal. | edumiguez |
| SAMSUNG | PN43H4000 | After changing the Y-sus TV repair kit, the screen turns off after being turned on for a while. | Poor quality transistor q5014 (fgd4536) triggering protection. | If you can't find good quality, adapt a normal 30f126 using a small heatsink. | mfelipe |
| SAMSUNG | P2279HN | Doesn't start | 5v2 line filtering capacitors with low capacitance c110/c111 1000uf x 10v | Replace them | Rodrigo V F |
| SAMSUNG | CL21C650ML | Vertical closed at the top | Replace diodo zener zd302, 24v e zd303 ,39v | DJ PITUKA | |
| SAMSUNG | UN32FH4003G | Turns on, appears for a few seconds, threatens the image and restarts | Capacitor c606, next to the tuner, was removed | Toni | |
| SAMSUNG | CL21C650ML | Vertical closed from the middle up. | Tsound la78045 com problem. | Replace and run to cocoa note: it can be replaced with la78040 which is fine. | digital system |
| SAMSUNG | 43H4000AG | Most defects are the power supply or eeprom, if it has voice, the screen flashes and the eeprom, if it flashes, only the LED can go to the power supply that is defective. | Power supply or eeprom | Do power supply or eeprom maintenance | beto2828 |
| SAMSUNG | CL29C650 | TV works - with audio without video -av1 -av2 --but displays characters -osd- | Enter service mode --mute --1--8--2--power on | Reset | EMERSON RIBEIRO |
| SAMSUNG | CL21Z43MQ K16E | No sound normal image | Lack of 8v on pin 87 of the micro it does not switch the sound passage of either the av or the fi in my case it was the l201 10uh and the zd 817 8v2 diode | TV was show just remembering that I released mute the output was powered oscillating perfectly but no audio I have to come to a technician to return the device so that's why | Eletrônica Muniz |
| SAMSUNG | LN32B350F1 | TV doesn't turn on | Open fuse and shorted MOSFET K10A60D | REPLACEMENT OF COMPONENTS | BICHARA |
