Sziasztok
Kérlek segítsetek egy alkatrész beszerzésében.
Természetesen leírom a hiba jelenséget is.
Adott egy Panasonic tx-32dk20d tv, mely egy sajnálatos kábeltv okozta földhurok miatt tönkrement.
(sz.gép-tv összekötve)
Pontosabban a tv videó jel bemenetei sorra tönkrementek. audió jel átmegy a kiválasztott beneten.
Később megadta magát a sz.gép videokártya tv-outja is. A kapcsolási rajzot bújva ( melyet ezen az oldalon leltem fel, köszönet érte) arra jutottam hogy a videó processzor a ludas. (VPC3215CB8TP - csattolva)
Tudnátok nekem ajánlani egy oldalt ahol meg tudom rendelni?
Előre is köszönöm!
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
Tisztelt Kollégák!
Bekapcsolás után hibátlannak tűnő kép jelenik meg rajta a lekapcsolásig.
Köszönettel veszek minden tanácsot a tapasztaltabb tagoktól,

Hi
I am having trouble finding any information regarding this product.
The unit powers up and the output is displayed on the screen for between 0 and ten seconds, the unit then powers down, the red standby LED on the front of the unit blinks then remains off for 5 seconds then blinks again.
This cycle continues until the power is disconnected, if the power is reconnected the unit goes back in to stand by (red led steady) it will then power on again.
Also in the error mode (red led blinking) and the power button on the back of the unit is pressed twice it will power up but this does not happen if the remote is used.
I have tested various capacitors and diodes but all seems well, I have also replaced the power supply with a reconditioned unit but this has not helped.
I have been unable to obtain any service information for this product.
So any input would be most helpful.
Thank you
