[Q] S2 Screen Flickering! Hardware/Software problem? - Galaxy S II Q&A, Help & Troubleshooting

My galaxy s2 (shwm250k) stock rom ics 4.0.3 while booting stucks at Galaxy s2 logo white lines start swiping across the screen and phone doesnt respond... I have to pull out the battery
Sometimes it happens in download mode also but not always...
Is it a hardware or software problem? Can JTAG get it solved by restoring a dumb/correct file?
THanks
