Tv has a big black in yhe middle,does that mean that the picture tube is going out

I giot a Toshiba recorder/player DR430 but it only show a black and white picture. What could be the problem?

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

The set has a high voltage problem, "the flyack transformer is defective" It generates the high voltage in the picture tube and with the help of the video circuits it produces a picture. It is not cost effective to repair the tv, cheaper to replace.

The tv have a dead part call the FBT-Flyback transformer,a big black block of plastice with a red wire with a black cap hook it to the CRT-(Tv picture tube).The FBT-give the tv highvoltages to the CRT(Tv picture tube).This tv is old model of an analog tv probally can't find part for it anymore.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Check youron screen menu setting for Closed Caption (CC) and turn it off.

sounds like an advanced closed caption service is on. go to menu then audio then closed caption and turn off closed caption.

check tubes...

You have the CC (closed captioning) turned on and it is set to text mode. Look for a button on your remote labeled "CC" or go into your TV menu and make sure the captioning selection is set to "off".
