PANASONIC | TC-29Z99L | DESLIGA SOZINHA | D511 COM FUGA | ||
Panasonic | Euro 4 | AV1 is ok but can't select AV 2 or 3 | IC 601 vidoeprocessor (VDP3120BC2 ) DC voltage pin 63 (AV2) and pin 64 (AV3) if near 0v (normal 1.5v) then replace IC 601 | ||
Panasonic | Dead with whine | HT low - ok on dummy load - LOPTx code 78550LT from WVE | |||
Panasonic | Z8 TX25CK1 | Lack of height | "modified" by replacing R603 from 3k to 4k7. | ||
Panasonic | Z8 TX21CK1 | tripping, relay clicking | C815 220UF 160V LEAKY | ||
Panasonic | Z8 TX21CK1 | int or no sound | C1201 470UF 16V | ||
Panasonic | Z7 TX21S3T | stuck in stby | EEPROM IC1205 (XL24C02PBAB) FAULTY, CHECK BY BYPASSING THE RELAY | ||
Panasonic | Z7 TX21S3T | negative pic with AGC overload via tiner (OK via SCART) | FAULTY EPROM. BEFORE REPLACING ENTER SERVICE MODE AND WRITE DOWN EPROM VALUES.CHANGE IC AND ENTER ORIG.VALUES, YOU MUST ENTER "SHIPPING CONDITION AUTOTUNE" | ||
Panasonic | Z7 TX21S3T | int. startup, int. blank raster, int. no remote operation | LOW SDA/SCL LINES, D307 BZY88C4V7 LEAKY | ||
Panasonic | Z7 TX21S3T | goes to stby after 5-10 mins | D1208 MA170 LEAKY | ||
Panasonic | Z7 TX21S3 | stuck in stby | NO 2.6V TO PIN 31 IC1201(Micro), R1218 O/C FUSIBLE 560K 0.5W PART NO. ERO50PKF5603 | ||
Panasonic | Z7 TX21JT | Reverts to st/by after a couple of hrs & keeps cutting out when sw back on | EEPROM vots had dropped to 2.3v (5v) due to D1202 going o/c - check other diodes in EEPROM supply line also | ||
Panasonic | Z7 TX14S3T | Wont find chans in chan search, those already tuned in are off tune & dist. Tall, flat & greyscale off in AV mode | eeprom Part number XL24CO20-AA cured the faults. Caused by dry joint on LOPTx earth tag corrupting EEPROM. Go into"self check" mode. Done by pressing Status button on the remote & V down on set. Shows OPT O2 on screen.Can't store PP until done | ||
Panasonic | Z7 TX14S3 | distorted pic and sound, appears to have no sync | EPROM IC1205 (XL24D02PAA1) |
