Good evening everyone. I have this lcd tv main 17mb140 with sound and white screen. The flat lcd is ok. The voltages on the main are present. What can I check?Is it a firmware problem? Thank you.
The 12v voltage is present. The t-con is integrated into the LCD panel. I need to check vgh and vgl.Measure if the t-con is powered by 12V. Measure the voltages on the t-con especially VGH(VONE) and VGL(VOFFE). If possible, disconnect one ribbon at a time to the panel and see if the image appears. Clean the contacts from the ribbons.
I tried with firmware from USB but nothing happens. I don't see anything on the screen. all white. I gave menu 1505+ok the same.Try recovery software for 17mb140. Titanium
Si installa con il tasto OK del telecomando premuto e il televisore collegato. Il tasto viene rilasciato quando il LED stby del televisore inizia a lampeggiare velocemente.
