Help HTC One S - display not working

[sap2000]

I bought new HTC One S in Germany on 13th April 2012.
On 28th April, just after 15 days, while I was browsing internet on the device, using wi-fi at my home in India, screen hanged suddenly.
I did a restart.
Screen never displayed anything after this.
Tried restarting several times. Tried hard re-booting many times.
Nothing worked till now.
Also called up htc support for help. The issue persists.
Just giving a try in this forum before I churn out $35 for paid service at htc service center.
Any help/suggestion is appreciated.

Did you try to unlock it so you can reinstall the ROM?
HTCdev - Unlock Bootloader

If you do that, it may void the warranty. I would call and ask before taking that step.

If it is a hardware issue replacing the ROM won't fix it. I can't tell you what the problem may be, but as long as you didn't mess with the software/etc, it is likely a hardware issue.

It seems this is an unusual/ unknown issue for which direct and easy resolution is not available as of now.
I would not go for any unproven solution. This device is my first android and it's pricey too.
Tomorrow I will visit nearest HTC service center.
Thanks for the suggestions and comments.

Got a new handset as a replacement since htc could not solve the issue.
It took a while (2 weeks repair + 2 week transportation India-Germany-India).
To start with they (store & htc) keep saying "NO" for the replacement but finally they did.
I'm happy for time being.
