| PANASONIC | TC29KL04 | Horizontal exit closed, risk in the middle of the screen | Polyester capacitor 390 nf, disabled | Replace o c563-394j 250v | JR eletronica |
| PANASONIC | TC 20A12 | Turns on and off after 1 minute | Resistor r 520 and 521 3r changed | Replaced the defect has been resolved | carlosgaucho |
| PANASONIC | TX-25LK1F ND-1230148 | Red pilot lights up and off without image | In principle tsound was an image then the pilot turned off and on | oliveira | |
| PANASONIC | TC14C6 MX1 | No audio | D2301 open | Replace. | joaomvjr |
| PANASONIC | TC14C6 MX1 | Doesn't start | Change r470k from the power supply. | joaomvjr | |
| PANASONIC | TC-20C4 MX1 | White screen without drizzle | Ic805 without the 12 volt voltage from pin 3. | See if the 12 volt voltage reaches pin 1 of the ic806. | Eletrosonic (Helio) |
| PANASONIC | TC-20C4 MX1 | Image flickers (it would be like deleting the image, the screen varies between darker and lighter) | IC601 pins with bad contact | Resoldering the ic601 and as a precaution, resoldering the ic401 and ic1102. | Eletrosonic (Helio) |
| PANASONIC | TC-20C4 MX1 | Return lines at the top of the image (about 10 centimeters wide) | The electrolytic capacitors c415, c417, c420, c421, c451, c452 were replaced and the defect persisted, the defect was ic401. | Replacing the vertical ic401 (in 19 years working with electronics this was the first case in which all the capacitors were replaced and the defect was not in the capacitors) | Eletrosonic (Helio) |
| PANASONIC | TC-29S10 NA5B(W) | The audio is missing and sometimes comes back playing on the varicap | I noticed that pin 45 of ic001 is always at 0.53 and should increase as the volume increases. | Resoldering the micro ic001 and taking advantage of and resoldering the vertical which usually has cold soldering. | Helio Eletrosonic |
| PANASONIC | 29G11 | Turns on standby and doesn't turn on | R808 (1r) r809 (1r) e r810 (2k7) | HP ELETRONICA | |

| PANASONIC | TC29KL05 | Does not connect horizontal output short | C563 open | Replace open c563 - d556 put by228- q753 put tip41- r768 10r 5w- q551 bu2527dx- r520,521 openers put resistor same value if not put TV starts to turn off by itself | ELETRONICA MAURI JUNIOR |
| PANASONIC | TC-14A10 | Slightly green screen | R336(open) | R336 (470 hom) replace the same | Jarbas (ELETRO-SERV) |
| PANASONIC | 29KM03 MX5ZB | Tvc turns on normal sound, screen with only 15cm of horizontal deflection and out of frequency. fly back buzzing (whistle) | Damper diode d-556 with a lot of leakage | Replace-556 | Assolini |
| PANASONIC | TC-29A8 | When turning on the power key, it turns off due to protection +b, it reaches 140 volts and then drops, if you hold down the action key and keep it pressed while turning on the pw key, the protection is disabled for image checking purposes. | Pin 3 line of the flay swap d560, 555, and 560 dz of 36v check r563,564,565,557,558 | BRUSKE | |
| TV PANASONIC | 29KL05 | Doesn't start. | Changed power supply | I replaced the strw6756 and it turned on, but then it turned off and I replaced the photo coupler and it worked normally, because the replaced photo made the +b from 140 go up to 230v and it turned off because the +b was high. | Adilson(formiga-mg) This email address is being protected from spambots.
