I have a A800 and after I pop in this code *#8999*8378# it apear to me “Test mode” .I went through “Test Lcd contrast” and I put there value 0 and pressed Ok, after that my screen was completely blue and i couldn’t see nothing.Someone please help me to tell me the steps after i will pop in again the code and tell me exactly what button i have to press

I would like to add the exact steps I performed to repair damaged contrast :

1.Insert code *#8999*8378#
2.press 8 then 5
3.insert a value for main lcd (for me 30 was good)
4.press OK (left button)
5.insert a value for small lcd (also 30 was good)
6.press OK (left button)

Thanks to Tbaba and Saphire!

Hi John,
Has your screen gone completely blank? I mean, can you simply not do the contrast settings or has the screen been rendered blank?
If it is the latter, try the EEPROM reset code given above and if that does not work either you may have to flash your phone.

Hello,

I hope you can help me.

I have a Samsung a800 here, i have used the code: *#8999*8378#

I was in the menu, i was just looking through some of the options, i clicked on lcd test, i pressed the confirm button and then my screen went blue (blank) i cant see anything now, ive taken out the battery and put it in again, didnt help, i can just use my pin and get into the phone, but with no screen, just blue light, thats it.

I have used the reset codes: *2767*3855# and *2767*688# but that didnt work either, the screen just started blinking on/off/on/off with the light.

Do you have any tips for me

Thanks

John
