Sziasztok, Sátoraljaújhely környékéről keresnék olyan emberkét aki bele tudna nekem égetni egy általam vitt tartalmat egy Samsung k9f1g08u0m nand chip-be. Mobilis vagyok kb 80km-ig :) Természetesen nem ingyen kérem. Előre is köszönöm. Üdv.: Irkax
Samsung UE40F6200 táp hiba
Üdv mindenkinek! Ebben a készülékben lakik egy BN44-00616A táp panel. A készenléti táp IC (SPS1013P) - lábán zárlatos lett a tárcsa kondi (101 1KV) Ez vitte magával a biztit, a graetz-ből két db 1n4007-et az ntk-t, meg a főbiztit. Az IC-n kívül a többi hibás alkatrész cseréje sajnos kevésnek bizonyult ahhoz hogy elinduljon a készenléti táp. Sajnos az IC adatlapját sem sikerült felkutatnom, mint ahogyan a táp panel rajzát sem. Az IC beszerzési forrást sem találtam. A keresés folyamán több oldalon említik hogy talán helyettesíthető a LNK584DG IC-vel. Ha valaki tudna valami infóval szolgálni ezzel kapcsolatban azt nagyon megköszönném.
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
