Panasonic Repair Guide: Common Issues and Fixes
Brand | Model | Fault | Detailed Problem | Solution | By |
---|---|---|---|---|---|
PANASONIC | TC20RM10L | Horizontal shaking and losing width | Changed resistor r502 | genilson | |
TV PANASONIC | 29KL25 | This TV arrived at the workshop with normal sound but with a horizontal scratch | Checking the circuit I found cap c 563 330k 250v as I didn't find the same value I associated 4 of 100k | And defect resolved. | BF.COLATINO |
PANASONIC | TV20A10 | When turned on, the protection is activated. There is no sound and no image. | Diode d402 shorted at the vertical output. | Rubens | |
TV PANASONIC | 14RM15L | This TV was completely stopped and when I opened it and turned it on, I noticed that the r-850 resistor was getting very hot, causing the q-850 to short out, but when I replaced it, everything remained the same, not even the std-by LED lit up. | All vertical voltages are present except pin 5 which has 0v and should have 28v and pin 6 which has 15v and according to the service manual it should have 29v. | Solved, it was the micro | BF.COLATINO |
TV PANASONIC | TC20C20 | This TV has no color, I checked capacitors near the do-it-all, resistors and everything, and it didn't solve it | Solved, it was the tda4665. | BF.COLATNO | |
TV PANASONIC | 14RM151 | I received this TV when it was stopped, and when I turned it on I noticed that the r-850 resistor was getting very hot. | The cause was the transistor q-850 shorted, I replaced this tr and even so the device still stopped, I noticed that in the lamp in series the device showed consumption and I found the zener d-883 shorted, after replacing the device the LED turned on std-by and it started to work on and off and with the vertical closed, I tested the entire vertical circuit and even replaced the vertical output but the defect persisted.. | Resolved, it was the micro. | BF.COLATNO |
PANASONIC | TC 20C6 | TV oscillates and returns to stand by. activates protection | Drop q503 . if atv works replace d528 | D528 shorted | samuel leite |
TV PANASONIC | TC14RM15L | This TV works all blurred as if it were the socket and turns off. | Defective an15525 vertical output. | Replaced and resolved. | BF.COLATNO |
TV PANASONIC | 29KL04. | Q753 shorted from emitter to collector. r768 open, 10r 2w. | Defect in correcting the cushion effect. pin cushion circuit. (solved) | BF.COLATINO | |
TV PANASONIC | TC 20C7 | Side lane | The defect was in two electrolytics that are next to the power supply's chooper transformer. values 47mf/16volts | BF.COLATINO | |
PANASONIC | TC1410 | Does not turn on, in the c823 it measures short | D817 shorted | Bruske | |
PANASONIC | 21FX32L | White screen with lines | Broken print on rgb +b line | luiz gonzaga da silva | |
TV PANASONIC | 29KL04 | Doesn't start | Horizontal output shorted. When replacing it with another one, it heated up too quickly to the point of burning your finger if left standing on top of it. Checking a little more, I found d 556 with a leak. | Just replaced it and stopped testing and everything was fine. | BF.COLATINO |
TV PANASONIC | 14 TC14C4 | White lines at the top of the screen | I changed the cp px of the 100/35 volt vertical TDA. | BF.COLATINO | |
PANASONIC | 14R12 | Turning off | The TV turns on but passes for a few minutes and turns off, the protection circuit comes into action, turning off the TV. | Capacitor c 519 of 333 mf 160 volts sem carga. | BF.COLATINO |
PANASONIC | TC29A11 BR2 | Turns off a few seconds after power on | X-ray acting | In this case the defect was in the vertical ci, it activated the x-ray protection, pin 36 of IC 601. This ci (vertical) was replaced and the TV started working normally again | dias |
PANASONIC | SA-AK78 | F61 | There is cold solder on all relays. if it's normal, change the stk-470-050 | aureliopr | |
PANASONIC | TC-14C7 | Vertical closes after some time of operation | Resolder the ic401 pins, including the heatsink pins | MARCELO FOUREAUX | |
PANASONIC | TC 29A8 | Volume at maximum, can't lower it even with the control | D 2312 as leakage (6.8v zener) | CABEÇÃO NATAL | |
PANASONIC | SA-MP11 | Mains input fuse blown due to lightning, when changing the fuse it blows again. | Audio output short ic501 | This email address is being protected from spambots. You need JavaScript enabled to view it. |
