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?

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?

Még nem szedtem szét, de a címke alapján vestel bele.

Sziasztok, fenti LCD-ben nehezen jött meg a kép, inverter átforr. ill. csavarok meghúzása után azonnal indul, de villog a kép. Ebben kérnék tanácsot, mély tisztelettel. Üdv: Imre
