Ennek a fentebb leirt tv nek kellene a szerviz menü elérése, kb egy centis fekete csik látható a képernyő jobb oldalán,illetve a szineken is kellene álitani egy kicsit,mert a zöld egy kicsit sok benne.
Ha valaki estleg már találkozott ilyen szörnyeteggel.
hang van kép nincs g2 felcsavarva visszafutásicsíkok megjelenek.
RGB vég cserélve probléma maradt.
Lehet hogy TDA12025 ic kellene cserélni?
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
