Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILCO | PH21M SS | Doesn't start | The LED came on when activating the power, the LED kept flashing with noise in the chopper | D455 diode shorted, just replace it and run to the hug. God bless you all. | Eletronica alvorecer |
| SEMP | LC3245W | Bad audio, failing | Preamplifier power supply low | I removed smd resistor r201, electrolytic capacitor c204, smd capacitor 203, pulled power from l837 and connected it to terminal 8 of ci n201 which makes the preamplifier, it was 100%. I did this because I struggled a lot trying to resolve the original circuit power supply and gave up, TV resolved and customer satisfied. | Marcelo da eletronica |
| TOSHIBA | 42XV600DA LC420WUN | No image (backlight), normal sound | Inverter board with swollen capacitors, memory u1 burst, transistor tp22 shorted | As I didn't have the memory, I replaced the board directly, it was 100%. | PL ELETRÔNICA |
| PHILCO | TP-2054 | Sem video frontal | Q-340 smd | Replace it for another like it | ELETRÔNICA CAVALCANTE MARTINÓPOLE-CE |
| PHILCO | PH21MSS | It didn't complete the sides and it didn't turn on, it was the diode d554, it was shortened, I replaced it, it turned on but it didn't complete the sides, I found the r 455a open 12k | Replace d554 e r 455a | Eletrônica Alves | |
| SONY | KLV-22BX350 | Half (center to top)picture only screen | Same as above | Half to top only bright | Damu |
| AOC | D32W931 715G3261-P02-000-003S | Dead TV doesn't turn on anything or LEDs | On the power supply board in the secondary 5v area exhausted orange capacitor c958 330uf/16v original elite brand capacitors | Replaced orange capacitor c958 330μF/16v placed new epcos 330μF/35v 105ºC working normally again, it is good to replace all 3 in the 5v area, c958 330μF/16v,c960 470μF/16v,c985 220μF/25v | Ricardo Montes |
| SEMP | TV2934(B)SL SK91 | On and off, with cushion effect. | Capacitor c311 47uf/200v dry. and diode d306 ba158 shorted | Replace c311 e d306 | MARCONES DE ARARIPINA PE. |
| MITSUBISHI | TC-1410 1410 | The power turns on, it stays in stand bay, when you turn it on, the LED goes out | 6r8 3w resistor r571 open and cap c567 shorted on pin 9 line of the flay bak | Replacing the two components solves the problem | pedrinho cachoeirinha |
| LG | MCD606 | Tsound was no lighting on the display | Open power supply diode 931. | D931 diode replacement | eletronica d.olho ,,paulo |
| LG | RP-14CB25ABRS | Vertical fully closed, only line in the middle of the screen. | Change the resistor (r313) and the problem will be solved. | Wellington tec | |
| PHILIPS | 21 PT5432 | Swinging vertically green screen and disconnects ci of the kinescope board loose pins resolder and replace c 2200 25 volts at the power supply | Electrola 2200 25 vlt | luiztvsom | |
| LG | 29 MC022A | I'm sound | Dried solder | Resolder the two cis, the sound output and the memory | bse eletros |
| PHILCO | PCS 2976S | Flashing image | If after changing the vertical ci and using the 8177 and the image keeps blinking when connecting the antenna, you have to use the 8177f ci | Replace 10k r703 with 20k | Angelo |
| LG | RP-20CC97 MC-059A | Blinking led | Dz851 6v2 | carlinhos100 | |
| PHILIPS | 42PFL6007G | With sound without image with backlight ok and giving small blinks in the lighting | Short defect in the screen killing the t-con voltages | T-con fhd tm120 ver 0.3 voltages with the screen flats disconnected vin 12v9, hvdd 8v37, vcc18 1v83, vcore 1v81, vdd 16v71, vgh 26v94, vgl -4v95, vconl_fb 7v34 | BRUSKE |
| SONY | HCD-GT888 | Sound works normally with audio. The display does not light up and the red volume LED does not light up, except for the USB one. | Burning of the smd transistor, of the led driver circuit, which stabilizes the 13.5v voltage, it is located on the side PCI close to the CN 601 connector that comes from pin 16 which is the +13.5v led | Replace of q716 or 2sb1710tl link for replacements (https://alltransistors.com/crsearch.php?mat=si&struct=npn&pc=100&ucb=1500&uce=800&ic=5&tj=150&hfe=8&caps=to218 | Roberto Curto Circuito Serviços |
| CCE | HPS1471 | Black stripe on the left side with ghost-like shadows | Put an 18 k resistor on top of the r.414 resistor and then | eletronica publisom rgn | |
| PHILCO | TPC2910 . | This TV wouldn't turn on, it came with a cricket-like chirp, the cause was the d406 horizontal output damping diode which was shorted, I replaced the diode, the TV turned on more with the expanded width, I scanned the ew circuit and found the q405 smd shorted bc858 pnp can place a bf423 respecting its emitter position connected to the base of the q403 bd238. | D406 and q405 bc858 smd polarizing base of q403 bd238. ew circuit transistor. | Replace q405 and d406. | <small>This email address is being protected from spambots.
