Question about Hitachi 43FDX01B TV

1 Answer

Poor color My Hitachi 43FDX01B TV has worked great for six years. A few days ago I noticed the color not as good, i.e. flesh tones were reddish and the overall picture was darker in color tone. I had the color setup on UltraAI since we had the set. Everything was OK. Now I've had to adjust the color tint down and turn the brighness all the way up. Even tried adjusting the tint, but just not as good. Obviously, something has gone wrong, since I've never had to adjust the color at all. Is this a common problem with this TV? Is this a major problem to get repaired? The convergence looks fine, no problem with that.

Re: poor color

I am about to say something that may sound stupid but it sounds like you are experiencing this. After years of use you CRT guns in your case the gun in each one of your CRTs(RGB) begins to oxidize and decrease in its ability to provide electrons for the scaning beam this creates a dark picture. Common problem? yes, over time, but for it to happen in just six years is strange but it can. Major Problem to have repaired? No, the technician will use a CRT rejuvenator on all three of your guns and then balance them and you are off and running. Now the other problem that might be occuring low CRT anode voltage. this could happen. Common problem? yes, it is the best choice Major Problem to have repaired? yes and no depending on which components are bad.

Well i really want to know what level the coular and brightness lvel has to be on a toshiba t.v

You can set these controls to your liking, though a lower brightness setting might increase the life of the screen. First, set the brightness and contrast to a level that is pleasing to the eyes, then adjust the color to look realistic - enough color without being disturbing. If faces area look greenish or purplish, then also adjust the tint (sometimes called Hue) until you get accurate flesh tone. Flesh tone is the best thing to adjust for; when you get good flesh tone, the rest of the picture will look great. ALWAYS make adjustments during a live news broadcast, which tends to have the most accurate balance of brightness, contrast, color level and hue. Note that commercials are all recorded in different studios with different settings, and will usually not look right - it's best to just live with this than to constantly readjust the TV. There are also DVD's available which walk you through proper TV adjustment.
