You have either loose conections on your internal wirings for the lcd's or you have damaged lcds and/or bad control board. Either way it is a problem that only a trained tech can help, not an easy fix for users, sorry.

Dell Laptop pinstripes on screen


Sounds like the Graphics Adapter has gone bad. If you connect a External Monitor do you see the same? If you boot to Safe Mode do you see the same? Has the Laptop been overheating? Has the Fan, Vents, and heatsink been cleaned recently? Any damage?

I have a samsung tx-t2782 with red green and blue pinstripe running horizontal across top of screen. not a ground loop and theres no magnetic interference.


hello spins,
If your problem just pinstripe on top of screen , but picture ok (normal in picture), try it to enter the factory mode. In standby position press info-menu-mute-power. Enter to deflection adjustment- choose - vamp (VA) or v shift (VS). Change value data by pressing + (or right cursor) and - (or left cursor) to shift or increasse amp. If it work, your tv will normal.
But its nor working, you should call samsung technician.
Good luck.

My sp 4805 shows vertical pinstrips once the screen comes on, can this be fixed?


Hello,

Check on the thin ribbon cables that go from the LCD screen to the PCB were shorting out/making poor contact. For me it was due to the position of the PCB, but in your case the ribbon cables my be coming unglued from the LCD because of heat or age, or both.

Another thing that could be happening is that the controller board is crapping out on you, open up the projector and see if there are any capacitors hit with the capacitor plague or the like.

If it's a really nice projector, then you might be able to find a replacement controller board on eBay.com, they have quite a few. Otherwise with some searching you might also be able to find a replacement LCD panel.

Hope this helps!

Pinstripe cinema display flickers on momentarily then goes black. Image comes back for a split second while when power light glows steadily then goes away while power light flickers. this is a 22"...


when the screen is black and the power light is steadly lit, shine a flash light at the screen. if you can see something, the inverter board is bad and the back light cannot turn on. if the power light flickers, reseat the power plug and put your ear to the back of the monitor where the power plug is. if you hear a buzzing or any high pitched noises; the power supply is bad. use the macufactures warranty for repairs.

Verticle lines through screen


Many times this is caused by a poor connection at the circuit board ribbon connectors to the boards, pull the TV cabinet off, unplug and re-plug all the connector to the boards a few times, take care not to damage them.

Horizontal 'pinstripe' lines on all channels


sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.
