Samsung S3770k white display problem

[code_raiser]

Dear Members,

I have Samsung S3770k with white display, on powering up display flashes as white then complete black. Set is working okay after white flash without display. I can hear startup sound and incoming calls. I have changed display, cleaned display connector, still same problem. Please help me what to do?

Thanks
