Title: Hitachi 32LD6600B - Vestel
Post by: Turnip on September 05, 2010,12:24:10

Hi Folks,

Have one of these where screen is awful bright but shows weak OSG and/or pics - sound is OK.   Scarted out to another set and pic is OK.

Replaced main board from scrap - same

Think to attach my file on the model as some others of us perhaps should - well, especially those who complain about our Quuq, Sparkily.

Screen or LVDS  ? - Chris

Hi Sparky, and thanks,

Checked and found just one fuse - F1 of course, and it was kosher. There were lots of other '0' res links as well - all OK.

Think to find up a piccy for those of us that like 'em - fuse outlined - Chris

Chris, there is a 2.5v reg. on the screen driver that can give problems ( 11172.5SJ) gives low output. Also is there 12V on LVDS?

Thanks Stellaman,

No 12v on LVDS,

Will check - that 2v5 reg -  may get me my shorty bench back for the next one -  Chris.

Hi,

Just had a chance for another look at LVDS - Reg UP4 (L1117DG) output OK at 2.5v, found no 12v on lead from main board but Buck diode DP4 had 13ish volts on it.

Any other thoughts ?   Chris.
