this sounds like screen burn with rear projection and plasma when a picture is left sitting still on the screen sometimes it will burn in to the screen rendering it useless i left my ps3 paused on my old tv then when i changed to bbc one it still had a faint call of duty pause screen in the back it can vary from things like that to logos to your black rectangle the only way of repair is by replacing the screen all toghether i would advise you to just take the screen off and start using the tv as a projector if you cant find a screen it is only a bit of ribbed plastic but very hard part to find
Hi, Do you see same solid black box in all inputs or just in dvd picture? If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings. And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function. Hope this will solve your TV problem. Thanks.
the red flash you are talking about im assuming is the screen going red that usualy means a red picture tube they break down one way to tell turn the red screen control counter clockwise and see if you can control the tube gain and then you can lightly tap on crt neck and i do mean carfuly and see if it flashes it most likely will and you would need to change the crt and reset it up
module problem take it to a Authorized dealer or a NESDA dealer service manuals hard to say if available since analog TVs are slowly going away and parts well another story might as well go buy a new HDTV set as a CET no garuntee how long it will be analog TV parts will be discontinued. FCC has alot to do with it.
If it was the lamp it would do it with DVDS too! I would ask for a new reciver because the only way the tv guy could moniter your tv picture is through the same box and tv! you need to compare....if you have another box in your house switch them and see what happens...sounds like a signal problem!
We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.
