Sziasztok!
Samsung UE32K5100 tv-hez bontott BN94-10853P main board-ot keresek .
Köszi, colore
Kedves Kollégák!
A képernyőn, középtájon, kb. ujjnyi széles piros csík látható. Ettől eltekintve, a készülék működik, de így szinte nézhetetlen. Nem tudom, hogy az LCD panel rossz, vagy a meghajtó elektronika szállt el?
- szerintetek javítható-e? Érdemes-e javítani? A készülék kb. 2-3 éves lehet.
- ha javítható, vállalná-e valaki? (Én már nem tudok/akarok hozzányúlni.)
Előre is köszönöm.
MODEL: Most Samsung plasmas
ISSUE: Cannot identify whether failure exists in main board, control board,
sustains or PSU.
DIAGNOSIS: Locate test header on control - should be 4x2 or 6x2.
Jumper appropriate pins (refer to service manual or PCB)
If you get test patterns:
- sustains, PSU, control okay
- main bad (control POSSIBLY bad - if input receiver bad)
If not:
- sustains, PSU, control or main are bad
Then identify failure in PSU - test output voltages
- if bad, fault lies in PSU, shorted sustain or main not turning
the PSU on
Then identify sustain board failures:
- unplug X-main, check if powers up and Y-main functions
(dim picture)
- unplug Y-main, check if powers up
(no picture)
Then identify control board failures:
- test SMD fuses
- scope LVDS waveforms going to control (if possible)
Might be main board failure. To confirm, test main board:
- blindly select audio source using INPUT button
