I have a PCG-K15 series laptop and I reviewed both these instructions about disassembling a PCG-K series laptop; your instructions are very helpful. The problem i’m having is that the LCD screen flickers on startup and get jiggly and produce multi-colored lines. After a while it stabilize then goes black. i replaced the inverter board with a factory new inverter and it does the same thing. Should i replace the LCD screen?

Graeme Pearce,

I have a PCG-K series laptop. When I move the screen, it ‘flickers’ in the sense that it goes black and then back to picture. ONCE it has gone completely black and went into hibernation or suspend or whatever, and I had to turnit back on – when i did the screen was fine. Only seems to happen when i move the screen from open to closed numerous times. Does this sound like an inverter/cable problem, or an actual backlight problem?

It’s hard to tell without looking at the laptop. Could be bad connection, bad cable, failing inverter board, etc…
In cases like that, I disassemble the display panel and try moving/wiggling the video cable while the laptop is turned on. If moving the video cable affects video on the screen, most likely the cable is bad.
Also, I try reseating cable connectors on the inverter board and back of the LCD screen.

I reviewed both these instructions and also the one about disassembling a PCG-K series laptop; your instructions are very helpfull.

I have a PCG-K23. I have noticed, on occassion, that the screen will start to get jiggly and produce multi-colored lines. This has been continuing now for about 1 year and has happened only about 6-8 times. Initially I was able to use the Start/Shut Down command, wait a couple of minutes and then re-boot sucesssfully. Lately the screen turns so bad that I have to shut down with the power button, and it’s more frequent.

I read in a previous post that you believe this type of problem could be the LCD cable, Given that my problem is intermittent and that the screen display recovers completely after a re-start I intend to use your instructions, open up the screen to access the cable and then disconnect, use contact cleaner, and then re-connect. Does this make sense? If the problem persists which components dou you believe I should replace?

Thanks,

Geovanny,

could you tell me please how i can replace the inverter of my Laptop Dell Inspiron 1525, i
don,t know how to take out.

In Dell laptops the inverter board is mounted to the bottom side of the LCD screen.
First, you’ll have to remove the LCD screen. After that you separate inverter from the screen.

hey, i was wondering that if i just opened up my viao s series to do some cleaning, when i put everything back, the lcd should work right?

however i have checked again and again i find no reason for the lcd to not have power, i have checked it has totally no information displayed, but on an external one it works

could it be a broken latch detector?
how do i locate it by the way

Worked like a charm. I have a different Sony laptop but went through same steps.
