Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| AOC | LE19W037 | Doesn't start | Capacitor on the power supply board position c911 with high ESR. | GARGAMEL | |
| CCE | HPS-2005 | Turns on with sound, and without image | Ceramic capacitor c410 close to the horizontal output tray. | Replace c410. 100pf/500v close to the horizontal output. | MARCONES DE ARARIPINA PE. |
| PHILIPS | 14PT316/78 | TV without audio, doesn't even stream it, it doesn't speak | Q 7956 smd bc857 killing the audio signal | Remove q7956 (in my case it solved it) | gdp2 |
| PHILCO | TVPH24M LED | Turns on normally, after a few seconds or minutes the screen goes off, and the standby LED comes on, along with the voltages on the cable that goes to the screen LEDs, drop from almost 70v to 12v | 1 LED on the screen burned out and as it was in series, it left another 9 LEDs, off, a jumper was made and it was ok and it never turned off again. You can also notice when the screen is on if tsound is a dark spot, then it is a burnt LED sign | Rodrigo Coelho | |
| SHARP | LC-52R64B | No hdmi input works | 3v3 power supply of ci sil9185a low around 1v2 | Check smd transistor close to sil9185a. 3v3 power arrives at the transistor but only 1v2 comes out. | rafaelmoraes99 |
| LG | 32LH570B LA66K | Doesn't start at all | C5608 in Kurdish | Replace it | MARCELIO DREISSIG |
| LG | 21FJ8RL | Horizontally turned, i.e. image lying down (like bars) | Altered 22k 512 resistor | Replace r 512 | ON-PLAY ELETRONICA |
| 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 |
| TOSHIBA | TV 2988MMS LEM9 | TV doesn't turn on led blinking straight away killing the tension of the sound output funny that when you release the output it returns to normal leaving the impression that I had a shorted output I even had to change it but it didn't solve it | C631 blue polyester 1v7, 1k63 | ELETRÔNICA MUNIZ | |
| PHILIPS | 21PT9467S/78 | Flickering black streaks at the bottom and top after 20 minutes on (vertical defect) | Resistor r 304 changed, may be measuring above 225r | Replace for a new one of 220r | Paulo Sertel-Itararé Sp 2018 |
| PHILIPS | 32PFL3605 | TV turns on slogan appears and screen goes off normal audio | Broken fountain | Just put a 10k resistor on pin 15 of the ci oz9977 (u401) to ground | Laercio umuarama |
| PHILCO | PH39E53SG | The TV turns on, the LEDs turn on and then turns off, leaving the image in the background and the sound. | In my case tsound was a burned out LED on the bar. To test without opening the panel, measure the LED returns, the LED bar has 8 returns, measure from n1 to n8 if one of them gives a different voltage from the other, the LED is open or shorted. | Removing transistor Q3 on the inverter board removes the protection and the LEDs remain on, but the correct option is to open the panel and replace the burnt LED or replace the entire bar. (hugs, we will post more tips tsound technical friends) | PRO PC ELETRÔNICA E INFORMÁTICA |
| SONY | KDL-50W705A | Led stand by pisca 8 vezes | Buses. or reverse | Bus replacement | ROGERIO FEDERAL |
| STI | D3277 | You plug it into the socket and the green LED lights up and doesn't do anything else. | Problem software | I downloaded the software from the sti website...unzip it and place it on an empty pen drive and insert it into the first USB port...plug it into the socket with the power button pressed...it should turn on with a blue screen and start the process | ROGERIO FEDERAL |
| LENOXX | CA310 | Does not turn on, the relay keeps hitting and blinking | R24 of 10r - it is an smd resistor marking 100 on top of it = 10r | ||
| LG | RP-20CB20A | Very low and hoarse sound you can only hear at maximum volume as if it were memory | Resistor (r625) de 22k | Replace for the same value | Eletrônica Bastos |
| SEMP TOSHIBA | 40L2400 | TV won't turn on stand by LED off | Tsound were all initial voltages except 3.3v on the n805, the output was 0.8v | Replace do ic n805 | Paulo Pinho |
| CCE | HPS 2070 | Does not turn on, LED blinks | Q402 short and fr401 open, and capacitor c829 dry. | Swap q402, fr401, and c829. in my case, I replaced the q402, bu1508dx 1500v / 8a, with c5802 1500v / 10a. | MARCONES DE ARARIPINA PE. |
| PHILIPS | 21PT5433 | High power supply and turns off gun protection | R3519 changed 3k3, it was 34k | To replace | Dj Velk |
| SEMP TOSHIBA | TV2998DS | Turns on for 5 seconds and turns off | R886 100k open ovp protection | Replace r886 100k | beto2828 |
