Sziasztok!
Samsung PS50B430 készülékben rendeltem az ebay-ról a fenti jelzésű tranzisztorokat (5db), de az LCR-T3-as műszerem nem ismeri fel egyiket sem, pontosabban az 1-3 láb között kondinak ismeri fel ESR 17 ohm és 3300 pf értékkel. Kérdésem hogy ettől még jó lehet vagy meg se próbáljam beépíteni?
A másik tranzisztor (igbt) a 30f123-ból szintén 5 db-ot rendeltem, abból 2 db-t felismer (N_E_MOS) ezért gondolom hogy a többi esetleg rossz lehet.
Kicseréltem őket de eddig nem indítottam a tv-t.
Helló!
Egy kollégámnak keresek m az alábbi alkatrészt:
VCT49X7F PY F1 000
CW-29M204V készülékben lakozik. Újként elég drága leginkább bontott vagy jóárasított érdekel. Köszi, üdv.: Ízirájder
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
Sikerült megjavítanom a TV-t .A display csatlakozó volt rosszul feldugva ,szerencsére .Köszönöm az erkölcsi segítséget mindenkinek aki segített .Néhány fotót feltettem akit érdekel a készülék belsővilága.
Köszönettel Stefy
