Hi, I my laptop's screen is flickering pretty badly. It's mainly the left side, but it's getting worse. It flickers more when the charging chord and/or plug is touched or moved. It was used and was fine all day yesterday, and only started doing this late last night. I thought I just had it running too long and turned it off, but after turning in on this morning it's still doing it. It hasn't been dropped or got wet either. I'm currently typing an honors project paper for school snd the flickering is giving me a headache, so if anyone can help me I'd be eternally grateful.

Re: my screen is flickering
This is probably because of something wrong with your lcd invertor or your lcd panel, the best solution anyone can give u is to get this laptop to a service center and ask them if the invertor is good. if not the lcd panel is faulty. u need to replace the lcd panel if thats the situation

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. http://electronicshelponline.blogspot.com/
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.
Hi Kevin, My daughter has the same problem with her laptop, do you find that when you move the screen slowly back and forth it either stops or gets worse ? You will need to take your laptop in to an HP dealer and let them have a look at it. Regards :)
There are a few things left you can try. First take the battery out and make sure the unit is unplugged. Next push the power button a few times to discharge any power inside the unit. Now put the battery back in and while plugging in the unit see if the charge light comes on or flickers at all.
If it flickers and goes out, you have a bad power cord or worse a bad jack on the laptop's main board. If it never comes on, you have a bad power cord or mainboard. The battery is probably dead (doesen't have a charge left in it.)
You said this happens regardless of if the battery is inserted. Have you tried powering up the unit with no battery installed and just the power plug?
I'd see about gettting a replacement cord first. If that doesen't do it you probably have a bad board.
Hello, According to the manual for my Toshiba laptop, the price of the screen is about the third of the price of the laptop. Do the math. Before looking for a repair shop, investigate first the reason foe the Flicker. I just remembered: all screens flicker. But if they flicker at 50 Hertz you might notice it. The higher the frequency the less noticeable the flicker is. Check your graphics properties to find out if you screen cannot refresh at a higher rate than the current one (60Hz, 75Hz or higher). But beware! if you force it to flicker at a frequency that it cannot handle, you will damage it.
I had the same problem with the flicker. Mine was a Flicker followed by a greenish line through the screen. It got worse then after 2 months the tv stoped working the power didnt come on at all. I Im taking it to bget fixed. The guy said it has somthing to do with a burnt out switch in the unit.
