12-03-2009 | | Is this a UK model or US? |
12-03-2009 | | Sorry, I don't get it. What 'fault' are we looking at? Are you sure the Y Pr Pb cables are plugged in all the way? (Red/Green/Blue cables for video) |
12-03-2009 | | It should be Q502 on a heat sink next to the flyback, the h out, the blue cap that's shorted, component location? |
12-03-2009 | | Did you replace the bulged caps and make sure polarity was correct on each? |
12-03-2009 | | Do you have menu? You say sound but no picture but it are you running a souround system? More info. |
12-03-2009 | | Please do not do multiple threads. I will delet them. We are here to help each other and if you keep it in one thread it helps future 'seekers' find their answers. |
12-03-2009 | | Since Dell doesn't actually manufacture anything itself, you would need to find out who actually does make it.
Then maybe I might be able to match it up with a manual that I have.

12-03-2009 | | its much better to see in person. |
12-03-2009 | | could be the lvds cable, but one important question to answer first, what is the model number??????????????????????????????? |
12-03-2009 | Grundig CUC1822 no sound... | Grundig CUC1822 M63-115/9 IDTV 100Hz no sound, picture OK. Sound appears if volume is max. While volume increases week knocking hears in loudspeaker. Disconected mains switch's start switch and headphones jack, but no change. |
12-03-2009 | | I agree with Minnie on Horizontal Output transistor being: 2SC5148; Q502 (Q501 is indeed a 2SC3209, but its function is Horizontal DRIVER, not OUTPUT).
I DON'T agree with Minnie that Q502 (Horizontal output) collector to emitter should read shorted, t |
12-03-2009 | | Are you saying that Unit uses 100 hz power source OR you're inputting a 100 hz signal and have no sound until volume at MAX? |
