Question about Soyo 19" LCD Flat Panel Monitor

Random White screen On PB LCD 22inch

The screen goes all white and then sometimes its fine again and works for day's. It started to get more frequent and now happens almost always. When it does work and you don’t switch off the screen or allow it to go into sleep mode or hibernation it will continue working but when you allow the screen to go off and you switch it back on again it goes white. Tried to solder the dry joints but the problem still persists. Is there any one out there that knows what I could check next?

When the screen glows grey/white, it means that the T-CON board is bad or it is not getting the 5vdc from the logic board. or loose conection on the T-CON board which is part of the LCD panel assembly.
Does it look like this when it goes out? Checkto see if the 5vdc goes away when it goes out, the 5vdc is supplied through the switched transistor on the logic board..

Sanyo xacti digital camcorder screen not working when opened out


Hi!
It's most likely a damaged LCD cable which goes through the hinge - happens to many camcorders. You will have to contact your local Sanyo service center. I replace these cables for Sony camcorders every day.

Sorry for the bad news, but hope this helps.

Screen goes white all the time


There might be a problem with the LCD of the phone, you need to have it checked with a technician. I'm not sure if the phone got damaged due to direct heat of sun light. The phone's LCD is also sensitive and can only take mild heat. Might as well take it to a local techinician and have them evaluate the phone's LCD for you.

White Display


Here is two solutions:

1. Grab a LCD Color Tester, Run it through RGB.
- If it is still white its the LCD
-If it not at all either the inverter board is bad or the mainboard.

2. Sometimes its brightness control, look under the manual.

Well its not much of a solution but I have found a way to get on with it. I have set my monitor to turn off every minute unless am watching a movie oor something.
Once the screen goes white, I wait a minute then screen turns off and then I can use again.

White blank on acer 4315


Go to www.acer.com, choose Service and Support, choose Driver Download, choose Drivers & Downloads, select Product Line Notebook, select Aspire 4315, click Search.

The above should get you to here :
http://www.acerpanam.com/synapse/forms/portal20.cfm?website=AcerPanAm.com&siteid=7117&areaid=2&formid=3394#results

Click on "Flash BIOS v1.13 " which is the latest BIOS for the 4315.

Follow the instructions to download and extract the files.

In order to Run the Vv2-113.exe file, you will need to right-click on it and choose "Run as administrator"

Make sure your battery is fully charged before updating a BIOS and do NOT power off the laptop during the update process.

This seems to have fixed most of the white screen problems on the 4315 that I am working on. The Fn-F4 "standby" and power button (or FN key) "resume" process described earlier is worth remembering because I have still had a couple of the white screens with the latest BIOS. Both times seemed to be when the screen saver was trying to start (lots better than during the boot-up!), so I have changed from the Acer default screen saver to something simpler hoping that the change makes the problem less frequent.

My screen goes blank from time to time and when I turn it off and turn it back on again, it seems to re-boot itself and is fine. However, I have never had this problem with any other phone and fear my phone may be dying. It is only 1 year old and worked fine for the first 8 months I had it. But the blank screen seems to happen more frequently lately. I don't think I will buy and LG again.
