The screen on my big screen is black it still works i can hear the tv but just cant see the pictures


Hi,

If all the following apply to your set:

(1) Adjusting the brightness and seeing that video is present (just black)

(2) The TV's menu system is visible on screen even though no images are

(3) Your particular SHARP model supports picture in picture mode

Then I suspect that the problem is your TV's picture-in-picture sub-board. All external video sources & the internal tuners must pass through this board before being processed and displayed on the picture tube (even when PIP is not enabled). As far as I am aware SHARP does not provide this board as a spare part anymore, but they can be repaired at the component level if the failed component is a generally available device.

Regards

You have to get the exact type no. of the picture tube. Better buy a new TV. Picture tube will be expensive and no guarantee whether it will have sharp image l after replacement.

12 yr. old 25" G.E. picture fading


I gotta love it when people make up answers. There is no such thing as a "contrass module". I'm assuming the poster meant "contrast". The trouble is your 12-year-old picture tube. It's gotten weak and isn't getting as bright or sharp as it used to. Picture tube manufacturers estimate the useful life of a tube at about 7 years today. There are adjustments inside that might help some, but you need a new picture tube. It's going to cost a lot more than $60 to $75 for that. You're better off replacing the TV.

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

Samsung big screen tv has white dots thousands of them


My Samsung was fixed for "free." Call Samsung service 800 number. When asked why you are calling tell them it is about the white dots problem. The tech said he would help me solve the issue and provide me with repair order from a local Electronics dealer. I was given a work order number by the tech and did receive a call from the local repair organization. My DLP is over 36 months old so I asked if this was a "no charge" fix. He assured me that it is. Low and behold I am 100% satisfied with Samsung and the standing behind the product. The fix is a chip replacement that Samsung is well aware of.

Wide black area top of the screen.


More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.
