Üdv!
Mesterek, a fentilapon sorkicsere után nincs E.W vezérlés. Eredeti sorki. 13022002C (Ap8)ami az alján kilyukadt, cseredarab TRRO 0777. Kérdésem lehet nem csere szabatos a sorki? Ezenfelül ha valaki adna jó ötletet azt megköszönném.Menni megy a gép, csak a torzítással.
This elderly monster arrived with the error “ 4 blinks “ which the manual suggests is a power board fault
There are TWO power boards and a standby power board inside
On removing rear cover there were two swollen 220uf caps on the standby board, sadly replacing them the 4 blinks remained
Swapping the two power boards over[ as they look identical , gives a “ 2 Blink “ error , the limited info in the manual suggesting that the fault is on the lower board [ main 2 ]
Both boards have a PFC voltage of around 380 volts at switch on before the relays click out
I have done cold checks on both boards and there are no obvious differences
As the manual has only a block diagram of the power supply it’s difficult to be sure of values / voltages
Has anybody seen or worked one of these or similar beasts and managed to diagnose the problem
Thanks for looking
Regards Ken

Hi
I have a Panasonic TH-48LFE8E display in at the moment.
The standby (red) LED does not come on when the power is connected and the unit is not responsive to the remote control.
However when the power button is pressed on the set the green power on LED lights, but there is no backlight or other signs of activity on the LCD.
I have tried to obtain a service manual but apparently they are no longer available?
I have not repaired many Panasonic units and if any one can help it would be appreciated
