Üdv!
A napokban már többször előfordultam itt, bontott trafót kerestem... Most már megelégednék újjal is, csak ne kelljen KIT-ben megvenni... Ha valaki tud beszerzési forrást 13022001B vagy HR80306, esetleg FBT41280 trafóra, kérem segítsen! Szempont a jobb ár...
Köszi!

Sziasztok
Egy Panasonic led tv-ben találkoztam ezzel a megoldással, hogy a diffúzor nem plexi lap, hanem egy perforált papír a ledeken sincs lencse.
Hátha másnak is újdonság.

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
Hello, I am working on a panasonic tv that shuts down a few seconds after it comes on, blinks(red standby light remains on)three times pauses, and repeat the cycle. Any ideas as to what could be wrong? Thanks.
