(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.
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.
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.
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.
well just tube only has 80 tos hours on thes eok time for new tv lcd sharp samsung are best on market for pcie plamsa tvs also nice in those 2 brands i would say time t o upgrade u love it those parts not avb anymore u will have hell of time fixing it if i can fid u parts on top of it new lcd flats so much more cleaner better and save 500 watts a day pays itself ok
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.
IF THIS IS A LCD---TURN ON, AS NORMAL AND HAVE A SIGNAL INPUT,,CABLE ,SATELLITE CONNECTED TO THE ANTENNA INPUT .MAKE SURE YOU HEAR SOUND.. HOLD A LIGHT (THE BRIGHTER THE BETTER) IN FRONT OF THE THE SCREEN ('BOUT 3 INCHES)--IF YOU SEE A DIM PICTURE---BAD SCREEN AND THATS BIG BUCKS---IF STILL NO PICTURE--CIRCUIT BOARDS AND USUALLY THATS BIG BUCKS!! GOOD LUCK
