You need to re-calibrate the screen in the system menu. Sometimes you need to do this more often (up to 10 times). Pull out the battery for a hour before you start doint this.

White line on screen of ipad


This is quite a common problem but it is hard to say what is causing it. Sometimes it is "dead pixels" like what you got on a tv screen if you leave it paused on a channel for hours. OR it could be the processor trying to keep up with you. If you can afford to - try and restore the device and see if the line is still there and let me know.

Monitor has no display, f305, white coloured phone


hi, the reason you have got a white screen is due to a ribbon failing inside your phone, the ribbon sends data from the circuit board to the screen.
this is a very common problem on all flip and slide type of mobile phone, as the screen moves their needs to be this thin ribbon that must move with the screen to keep the connection between the screen and board, now what happens is that over time the thin copper wires in the ribbon break causing the data not to be sent correctly to the screen and this is the reason the screen turns white.

now you should be able to make and recieve calls as long as the phone is turned on how ever if your phone asks for a password when you switch it on then this could cause a problem as you cant see what your typing but if your phone dont need password then you can just turn it on and wait for calls to come through, the phone will ring as normal you just wont be able to see who is calling.

now to solve your problem you need to get the ribbon replaced, its not expensive to buy but fitting it yourself would be impossible as you need special tools to split the phone and to also fit the ribbon, if you take your phone to a small phone shop and not a big branded shop then they should be able to fix it whilst you wait as it only takes about 15min to fit as long as you have the correct tools

My samsung screen is white but it works ive tried everything, this hbas happen before screen going white and the battery had to be without juice to come back. it works but ithe screeen is white


hi, the main reason the screen turns whits is due to the thin ribbon that sends the data from the circuit board to the screen being damaged what happens is that the thin copper wires that are inside the ribbon ware and then break causing a short to the screen and this is what turns the screen white. this happens on most flip and slide phones as the ribbon moves when you slide or flip the phone so over time it becomes brittle and you lose the connection and this turns the screen white.

sometimes it will right itself if you open and close the phone a couple of times but this wont be a long term fix how ever it may be that bad that this will no longer work, its not expensive to get this ribbon replaced but taking you phone to a small phone shop would be your cheapest option.

Verticle hold transistor?


The vertical hold keeps a normal picture from rolling either up or down. You don't have a normal picture (raster) here.

The problem you are having is a vertical deflection problem. The screen is being compressed to a thin white line. It's probably a defective vertical output module or transistor. This part is not too expensive. Less likely would be a vertical deflection coil, which would be more expensive because its usually glued to the picture tube and harder to replace.

Good Luck!

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.
