Sony KDL-46Z4100 Color Goes Dark: After about an hour, colors returned to normal, than back to dark again?!???

I have the exact same problem after 3 years. Now the color is way off from the get-go as soon as the power is on. Just called Sony tech support they offer $579 + local tax for a refurbished same model. I think the offer is a bit off the chart, considering the price of a new set. And this is simply not acceptable from Sony. Please call them and appeal to them for a free fix. I will. Liz from CA

We've been experiencing it off and on for about 6 months. Two nights ago, it was really bad...today...its not there. It comes and goes. In our case its a blue stripe. We've seen it whether its coming from the cable box or bluray player. I haven't played with it too much, so I don't have a pattern of what it does and how to defeat it. I'd like a comment from Panasonic. Our TV was 5 years old at Christmas.

Unfortunately I just saw your post as I was looking for discussions regarding a problem that recently manifest on my 46VL150 from Costco. If in fact your 46V5100 is an identical model I suggest you return it ASAP! My problem is, as many have noted on their sets, the set turns itself off and the red standby light illuminates. No amount of turn off and on resolves the problem. Unplugging it for a protracted period gives you about 15- 20 minutes of "norma" play then the cycle repeats. Cannot comment on Sony repair yet since I am just now calling them. Good luck!

Hi, my friend bought her tv (save model KDL-46VL150) from a dealer around here and since january 15, 2010 has not been able to listen to it. It worked about 10 days, then a red flashing light came on et OFF went the TV. If I were you, I would return that model number. They all seem to have the same problem and unless you have bought from Costco the other dealers won't take it back (they sent you back directly to Sony who sent's you a repairman. And Sony is sure not in a hurry to fix it. She is still waiting for the repairman even after numerous phone calls and complaints. Check the web and see others that have the same problem. Good luck.

I think something like that happened to me... I Changed the colored video cables between themselves and fixed (blue where green goes and green on blue, or something like that) it... try different configuration with the RGB cable.

I found a partial workaround solution for my problem (like yours) of the unit turning off a few seconds after turning it on. I press (and hold) the Stop button, and then the On button, and continue to press them both until the blue SA-CD light and the blue MultiChannel light go off, and then back on again. After that, the unit works ! Except that the LCD panel remains blank. Many (perhaps all) of the front panel buttons work. I still need to experiment to see if the remote works, and to what extent.Sony gave me the choice of a refurbished unit, or to repair mine, under warranty.

I have been trying to do that same thing. Some scenes get messed up by the auto-exposure. A couple steps down in the settings you can change how bright or dark the picture is but that pesky auto-exposure is still active. Let's hope if they ever put up another firmware update that they include that functionality like when they added the timer function.

No idea. My tv never went black....just got darker and fuzzier over time but could still watch tv ok. Your issue sounds much more serious.

This is great TV just make sure you go to sony web. site to get update to fix intermittant light/dark issue.You might want to order some new HDMI cables that support 120hz cat.2 or b, price on amazon is the best for cables.The color in 1080p/i is WOW!!!!!!!!!!!

If you encountered this issue only under dark environment, when high ISO is applied to picture, the camera need to be fine tune it's dark noise. it is either need a parts replacement or re-calibrate dark level.If you were taking this purple color under day light, take a look if this picture is a flash picture. For some case, the color balance under day light with flash is difficult so that the Image Processor does not do a precise judgement. Turn off flash under day light will fix it.

Not too sure why this happens. Never experience this. The only reason that I can think off is when it gets dark the images are displayed by the infra red, night vision properties of the camera.

I am going through my second 40XBR4. The first had what seemed like flashlights shining diagonally from the upper left and right corners in dark scenes. I exchanged it for a second one and it sucks as well. I think the second one is going to be returned pretty soon as well and no more Sony for me.

yeah sounds like a dead pixel. problem is if it's just 1 you're SOL. I had this issue with my sony lcd and Customer Support said that they'll warranty it for 15 or more dead pixels. Luckily my friend run a PC Richard so I exchanged it. If you look close and its the shape of a rectangle on a grid then it's a dead pixel.

Try a different input on ur DVR that you know works correctly. If it still does not show color, u have a defective unit as the night/low light feature is automatic. These cameras are built very well and I have had no problems so far.

It sounds like the "backlight" in the screen went bad. if the backlight is going bad/dim, it will make colors look dull or washed out. However, if you think this is a software issue and not hardware, suggest you try to change your battery settings - change to maximum performance (instead of max battery) and see if that changes anything.

check your settings on the TV. Hooking my DC up to my Sony reset the "scene" settings for PC input and I have to manually set the colors back
