Sharp LC32LE700E TV (82 cm képátlóval) tápegység hiba miatt nem működik.
Ingyen, akár alkatrésznek is elvihető tőlem Gárdonyból.
Sziasztok!
A Hiba jelege hogy rövid üzem után a kép először teli fehéren világít egy pillanatra majd kis idő múlva zöld majd pirosan világit akár órákig is, hang van néha rendszertelenül beugrik a kép de vissza is megy pirosba.
-Eredeti hibája a háttérvílágitás kikapcsolgatott de ezt a inverter lefogócsavarjainak nem érintkezése okozta.
Előre is köszönöm a segítséget!
Üdv!
Kaptam megy ilyent.
Elindul, megy 10-30 percet. majd elmegy a háttér.
Van valakinek tapasztalata, tuti a háttér qka, vagy valami a driverben...?
Ez kellene bele?

Hi, mainboard Vestel 17MB70-5P. When turned on this TV, backlights comes on, I can hear the sound but no picture, just blue screen. When turned off to standby, the red and green led stays blinking. With oscilloscope I can see some signals in mainboard in cn26 to t-con. Previously on this TV have had some problems with the memory chip. Failure became suddenly, TV did not start anymore.
Can anyone give advice on this problem?
