How to diagnose Samsung plasma failure using test patterns
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
Samsung LE23R81B Nem kapcsol be
Sziasztok!

A tv-ben levő tápegység típusa BN44-00158A.
A panelen amit találtam hibát egy púpos elkó kondi,CB852-1000 uf-os kondi és egy KA431 sönt regulátor,ami az oxidáció során a lábai elrozsdásodtak.A hibajelenség az,hogy a PFC kimeneten a 380V helyett csak 320V-ot mérek,az 5,2V stby és a 12,24 Volt nincs meg a panelen.A biztosítékok nem szakadtak,összekötve a táp panelen a PS-ON és 5V stby-a feszültség mérésekor is hiányoznak az 5V,12 ÉS 24V.Cseréltem az FL922 IC-t is a hibajelenség továbbra is ugyanaz.Van ötlete valakinek ezzel kapcsolatban,találkozott már ilyen hibajelenséggel?

Köszönöm előre is a segítséget!
