Hi,

would be ever so thankful if someone has an answer to my odd problem. i have a ViewSonic LCD TV, model N3200w. It has had a recurrent problem with a yellow tinting of some of the lighter areas (highlights, but not the whitest ones) of the picture. Now it seems to have one permanent. What is this, and how can it be fixed? No, it's definitely nothing to do with the colour/hue settngs. This seems to me to be an error in the RGB signals, or something.

Also, I would like to connect a digital box to this tv, but the Scart input doesn't seem to recognise it. The tv is bought in Sweden (PAL B/G, and then I brought it to UK when I moved here (with PAL I). Is this the reason it doesn't work? Or, is it that this tv isn't HD ready although the manufacturer claimed so?

Any assistance welcome,

Thanks in advance,

EyeAm

Does the yellow issue occur with the inbuilt analog tuner, or just via the SCART inputs. What is the connection method between the digital box and the display, a fully wired SCART, are both the STB and display expecting RGB or composite.

The PAL I issue would only effect the tuner (ie off air analog) it will not effect the composite or RGB (SCART) inputs. That said very few displays these days cannot handle all variants of PAL, and PAL B/G and PAL I only really have variance in the sound carriers, so you might not get sound, but should still get pics.

Hi Cyril,

the yellow is there via scart (as in a dvd player) as well as "straight", via the antenna (analog). Weird thing is though, if I just have an empty screen (as in switching between scart inputs before the actual periferal is switched on for instance), the screen is filled with a clear, clean and bright blue without any yellowness. But, as soon as I get the periferal (dvd for instance) to kick in, the screen gets this yellow hue (and the clean blue turns into a sickly green). I should say that when I have used this lcd as a computer screen (via VGA) it also had this yellowish tint, but then more haphazardly distributed (whereas on a tv or dvd-image it's clearly in just the highlights).

Weird, eh?

Sorry, forgot you other question. Not sure what STB is, I'm afraid. It's a SCART (if it's fully wired I don't know. It's the standard SCART cable that comes with the machine). I don't use the composite for tv. I hope that gave you an idea....

Hi STB= Set Top Box, ie Sky box or FreeView/FTA box etc. You say you dont use composite, by that do you mean the seperate composite input, rather than the SCART input in composite or RGB mode, they can operate in either.

From the sounds of it there is a fault somewhere in the input stages, trying to diagnose from afar is probably not as effective as having a tech gander at it.

Ok, pity. I guess that makes it going into the bin. Can't imagine the cost of the repair to be cheap...

Thanks a lot for your try, Cyril, really appreciate it.
