You may have a problem with your lcd inverter, or it could be a loose wire, if you're able, take apart the frame surrounding the lcd screen and see if you can access the connectors. If that doesn't work you may need a new inverter which usually comes with the screen.

Lg r405 laptop screen flickering


most likely a loose connection if it is flickering.. if there are red squiggly lines usually means driver issue.. and if there are blue banding lines, typically means the chip is overheating/desoldering.

My TV has a severe flicker/jitter in the bottom left quadrant of the screen. How do I fix it?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Laptop screen suddenly starts flickering with warious color bars


Hi,

If your lcd screen got harizotal line ( Pink, blue or red ) and flickering, that means your lcd ribbon or board on back top was crack or faulty I believe your lcd screen model is LG Display. There are not have any way to repair it. You must be replace with another lcd but I suggest you to change it with Samsung brand lcd screen. You can buy new lcd screen from ebay.com

Screen got black lines across it


Across vertically or horizontally... It makes all the dif. It could be 3 boards on the set. The YSUS-main the YBU-upper/YBL-Lower. The Y buffer upper controls the top half of the screen, the Y buffer lower the lower half and the YSUS-main controls those 2 boards. They work in unison, when one goes they all fail. The other possibility is dry solder joints on the the D, G, E, F boards. All you would need to do with that is reheat the solder joints at the ribbon cable conx.

Canon EOS Digital Rebel XT: The upper lcd screen info flickers,some of the icons on the screen work normaly, but other icons are lighter and flicker. Im speaking about the portion that displays battery...


It seems you have a false contact in the upper LCD screen, its flat ribbon cable or the connector at the main board.

It is necessary to open it and check it.

It is fairly easy to do it, but if the camera has a warranty, I do recommend you to make it valid.

If does not have warranty, then you may try in do it yourself if you have some experience and skills to fix electronic devices, or pay to have it done.

Best regards,

Flickering horizontal lines


sounds like a problem in the horizontal deflection circuit.possibly a solder problem. try re-soldering the horizontal transistor, line coils and yoke pins.
