Ennek a tv-nek 5-öt villan a készenléti ledje, és nem reagál a távirányítóra, amúgy kép hang van.
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?
Sanyika
