Question about Hitachi 50V500 50 in. HD-Ready LCD Television

1 Answer

Hitachi ultravision digital widescreen

Help! Not only does my tv take a long time to warm up, but while watching tv programs, there are pale yellow splotches located in various places all over the screen! Hope you can help! Similar problem. But I have a blue color that looks like it is 'bleeding' from the the top of the screen, and the center has a red hue to it. My TV is also about 5 years old. I was afraid a repair would require replacement of some key components, but hoping it indeed just 'needs an adjustment. So, gotta find a TV chiropractor I guess.

    My Hitachi 50v500 which is about 5 years old has a blue spot in the center of the screen and at teh top center which is getting worse. Is this a sign of the bulb getting weak?

Try cleaning the 11 element lens just in front of the lamp housing. If this doesn't completely clear the problem, then one or more LCD panels are faulty.

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !
cheers!
Vern

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.



GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)

I Have a Hitachi Ultravision projetion TV Ned help to fix it.


This sounds like the solder joints on one of the convergence output IC's have cracked loose or the IC itself is defective and quitting when it warms up. The IC needs to be either resoldered or replaced.
