Here i habe a faulty C27A550U. The Unit has no backlight. Everything else is working fine.
The Main PCB is BN41-01652B with integrated LED driver. I can´t find any info or diagrams on the internet. Has anyone access to Samsung service files??? That would help a lot!!!
(The only thing i found is The "A" Revision on ebay)
Here is what i found so far:
The fuse for the LED Driver was blown. And blows again if replaced. (it´s located on the left in front of the big black coil)
When bridged, the display doesn´t start at all and the LED driver chip gets hot very quick.(located between the black coil and the flex connector) It is labled "bd9264efv" Can´t find any info on this one, too. Can you???
So, if anyone can help me with this one it would be great! Datasheets will help me a lot, too!!!!
