Make	Model	Symptom	Problem	Solution
PANASONIC	TC14C4/20C4	Burning f801 and f802	Ic802, replace c812
PANASONIC	TC14D1/20D1	Folding the image at the top	C412
PANASONIC	TC14C1/20C1	Loud sound and won't change channels	R881, r882
PANASONIC	TC-14C2/20C2	Unstable vertical	C410
PANASONIC	TC-14C2/20C2	Dead and beeping	Flyback
PANASONIC	TC-14C2/20C2	Image shakes when adding volume	16v power supply low and r863
PANASONIC	TC-14C2/20C2	Image very bright and does not darken	19
PANASONIC	TC20C6	Inoperative, relay knocking	Open r802 or r803 (470k)
PANASONIC	TC-29V50B	Burning of ic802(str), d184, c812, q804	In the first production batches the resistor r841 was assembled very close to the heatsink, which will cause cold solder heat dissipation and oxidation at its terminals. as this resistor is located between the drive and the base of the power transistor, this bad contact will cause IC802(str), d814, c812, q804	Solution: 1) after the burned components are replaced, the resistor r841 must be removed, checking that its value has not been replaced, if it has been, it must be replaced. if its value is ok, its terminals should be sanded and resoldered into its position on the board. 2) please take this countermeasure for all devices that pass through an authorized workshop for maintenance, whether the device is presenting or not problems at the power supply.
