PANASONIC	EURO 4	Int going into standby.	Replace c454 a 22nf smd, located near the frame o/p ic
PANASONIC	TC-21 S3R Z7	Picture fades away few seconds after start-up till no picture. sometimes no picture at all. sometimes picture ok for longer. sound unaffected.	Faulty joints on crt pcb. cracked solder joints at tube socket connections on crt circuit board. caused variable supply to crt heaters. resolder all socket pins to pcb.
PANASONIC	TX32PF10 EURO 4	Over a short period of time the convergence of the picture gets steadily worse. eventually it is so bad that even the teletext shows double or triple images when they are made up of a combination of colours. pure colours: red, green or blue are ok.	The tube must be replaced. apparantly this is a known problem to panasonic, especially on 32" tubes. it has been known to happen both in and out of warranty. so far panasonic when contacted have also paid for repairs when out of warranty 2 years old
PANASONIC	E110 NA	Image and text are to large on screen	Replaced flyback
PANASONIC	14B3T Z375	Excessive vertical overscan caused by a poor factory set up	Enter service mode and alter v size:-
PANASONIC	NVHD660B K DECK	When inserting tape, tape goes in, get a motor whirring noise, and tape ejects again with an "f02" or "f04" error. closer examination shows that tape seating correctly, but tape not being fed out to the head	Cause was the motor powering the main mechanical feed/load and eject gear, underside of main front right of central chasis. small plastic part on motor spindle under gear had split, so slipping. secured part and gear to spindle with super glue! ok now!
PANASONIC	NVFS90EG	Power supply problem, high frequency sound only !	Check / replace c9 1uf, 400v
PANASONIC	TX33AK10 EURO 5	Strange picture / bleary / movement blurr etc etc	This problem was caused by eeprom corruption, once the eeprom was reset the fault was cured note that after a reset reinstallation i.e. tuning will be required
PANASONIC	NV-HD100	Display dead rest of functions ok	Change transistor q1701 on timer operation board
PANASONIC	TX-32PK3	Reverting to standby at switch on	Replace c454 22nf surface mounted component. it is also worth examining the line output and power supply areas for poorly soldered joints
PANASONIC	TX28DK2 EURO 4	No surround sound	As mark said in a fault on the euro 4 , replace the tda2030.
PANASONIC	TX-14/21GV1	No operation, standby led blinking	Replaced c840 47uf, 25v which had gone low in value
PANASONIC	NVG30	Operates for about half hour to an hour and shuts down	Capstan ic located on the underside of main pcb was dry jointed due to exessive heat. remove and discard plastic cover and apply fresh solder removing old. also refresh heatsink compound.i'll try extending the heatsink too
PANASONIC	TX21V1 ALPHA 2	Bright red raster with flyback lines,shutting down after about 30 seconds with squealing from power supply	The fault was due to the supply choke to the red output stage on the tube base panel being o/c, i can only assume the shut down was due to excessive beam current, a long soak test proved all was now ok
PANASONIC	TX-2470	Cogging on vertical elements of picture, p.s.u squealing	Replaced c808 10uf, 50v it had gone low in value
PANASONIC	NVJ45 G DECK	Appeared to be dead like c1110 1uf, 400	Found c1125 and c1130 680uf, 20v leaking onto pcb. remove sm.tx and clean board

PANASONIC	TC2195DRS Z3T	Smps noise. low volt and high current on usyst, no screen or sound	Fbt tlf15606f
PANASONIC	NV-HD675 Z-MECH	Intermittently shutting down with ho1 in display	Problem can be caused by stator board vek9017 but in this case the problem was the upper drum assy! the bearings seize up when warm!
PANASONIC	TX28W3 EURO 1	At switch on a strange sound comes and goes for a few seconds, no sound and vision	Check r622, q624 and t639
