Sziasztok!
A fent nevezett dióda egy Sony televízióban lakott.
Sasszi száma: FE-1A
Hq-nál néztem ők nem árulnak, adatlapot nem találtam.
Mivel lehet őt kiváltani?
Ha valaki tud kérem segítsen.

Sziasztok.
Egy ilyen táppal küzdök.
Tünetek:
Bekapcsolás után felszisszen, aztán a tápled elkezd villogni. 6 rövid, szünet. A service manual (30.old) alapján ez overvoltage/overcurrent protection.
TápIC: STRS5706. Feltöltöttem a táprajzot és a service manualt is. Az itt leírtak alapján IC csere, esetleg LOPTx csere.
Amit eddig elkövettem/tapasztaltam:
C608 10µ 50 cserélve (igaz nem low esr-re, mert nem találtam itthon)
C620 100µ 160v cserélve
60W-os izzóval nem indul. 40W-ossal második ciccenésre indul és 137V van a B+ -on. Az R607-en 45,3mV van. A Sens bemeneten 32V-ot mérek.
Szerintetek? Vegyem az IC-t?

Sziasztok!
Bravia KDL32L400-as tévével a következő a bajom:
Bekapcs, nincs kép, némi összevissza sávok látszanak a képen, hang és háttérvil. rendben.
Ha lehúzom, visszadugom az lvds kábelt, akkor a következő kikapcsolásig minden hibátlan.
Kábel, csatik basztatására nem reagál, táp rendben.
Valakinek esetleg valami tippje?
Köszi előre is!
Hello friends,
my SONY TV shows some missing LEDs I think:
After dissabling and measuring: The first and the last two transistors show 1,6 Volts. The second one shows 0 Volts:
Any ideas?
