I have been *window shopping* for a replacement TV for my living room because I have been experiecing a problem...well, not so much as a "malfunction", but more of an irritating defect that drives me so crazy, I rarely even watch movies on it anymore because of it.
I guess what I want to know is....is the problem my TV, OR my setup? I just do NOT want to purchase another TV only to find out the problem is something else.
Maybe I should have posted in the "structured wiring section?", I don't know, but here goes if anyone can help me at least "isolate" the problem, it doesn't even matter if it gets fixed.
Bought it '03, my KV-36FS100 sat on my living room floor for almost a month (past the return period). During that time, i had a DVD player hooked up via 3 foot component cables and noticed no ill effects.
Finally gathered 4 people to "hoist" my TV up into its cubby hole above the fireplace.
Since that time I noticed during dark viewing conditions and black scenes, the vertical brightness is not uniform. Now I know CRTs do not have uniform brightness accross the screen (so I have read), but I have never seen this before. The top of my screen is "whitish" and gets progressivly darker the further down the screen until about 1/3-1/2 way down it is finally "true black". Being a Sci-Fi buff, it REALLY sticks out like a sore thumb.
Calibration via DVE actually exaggerated the problem. I eventually went into the service menu and had to back off the sub contrast/sub brightness to where the top of the screen was "crushed" to black. That works okay for nighttime movie watching, but daytime viewing leaves the set "Dim", and playing Xbox on it is difficult because all the shadow details are crushed to black.
I *belive* the problem exists on all inputs, BUT...RF and composite are mimimal, if not, non-existant and its fine. However, S-video and Component the problem is DRAMATIC.
It bugs me that I don't recall seeing it in the first 30 days, but maybe I just didn't have it dark enough in the room to notice? OR...what really concerns me, is its a problem elsewhere and a new TV WON'T fix it, and I will have wasted money!
The current setup has total cable length runs of about 33'. I am using 3' AR cables for "jumpers", and the inwall cable is from bluejeanscable.com . So I don't have HIGH quality cables, but I don't have bottom of the barrel, either.
I have tried different jumpers to no avail. Since my TV is so far away, I was thinking okay maybe its an odd "ground loop problem", so I went so far as to take a source, plug it in to a UPS, and DISCONNECT the UPS from the wall, completely isolating it from the power-that didn't help either.
It doesn't matter what the source device is, its still noticable on S-Video and Component inputs. But what is odd, is if I turn off the source device (still plugged in), OR disconnect the source device, the screen goes to a perfectly uniform black.
So.....is it my TV, or something else?
HELP! i am thinking of buying a new TV, but if it doesn't fix this problem I'll feel like it was wasted $$$.
Thanks to ANYONE who can help!
