Title: Hitachi L32H01EA, No picture, only sound.
Post by: wilho on January 02, 2011,06:31:27

Hello everybody and happy new year. I have hitachi lcd-tv and there's no picture on it, only sound. Backlight seems to turn on and stays on until tv is turned of. I check the voltages from power board and the main board, and everything is what it should be.  There were no bulked condensator on power board. Im running out of ideas what's wrong with this.  Could the fault be in the inverter board? i havent check that out yet.

Power board: Vestel 17PW20V1
Main board: Vestel 17MB22-2

Sorry for being newb, but what you mean by tcon panel?

backlight turns of when i turn of tv. it takes about 10sec to backlight to turn on when i power the tv, normal time?

Hi all,

I am new to the forum.  I do appologise for resurrecting an old thread, but as I have the same issue, albeit with a different make and model 32" lcd tv.

I have added an image for the benefit of others.

What are the makes, models and amperages of the F1 and F2 Fuses, please?

Thanks Jordan.

Can you confirm that they are " MFU 0603 " please?  It's just on eBay, they look nothing like the ones on the t-con.

Many thanks.
