TP2 battery draining & overheating, before dying :(

[utestit]

Hi,

I have had a TP2 for several years, working fine.
Until couple of weeks ago, with no reason or event, the battery suddently went very hot, the TP2 would reboot on its own, the battery drained in 10s of minutes, then died.

I could not recharge the battery (orange led blinking during recharge), so bought a new one (HTC build).

I soft, then hard reset my TP2 - same symptoms.
I changed the battery to the new one - same.
I reflashed the ROM with latest ROM release (March 2010, 2.07.406.1) - same.
I did all above with no microSD card in - same.
I looked for parasite application running in the background (using SK tools), but found none.

I reviewed the forum & found no solution to this issue for TP2.
It seems however very close to issue encountered by other users on HD2/Leo. [such as HD2 overheating, not charging and rebooting - temperature monitoring - xda-developers
]HD2 overheating, not charging and rebooting - temperature monitoring - xda-developers
This would point to hardware problem - which is strange with a device I have had for years with no issue.

So symptoms with my TP2/Rhodium are :
. I can load my battery (to 100%);
. the battery will get very hot;
. the battery drains quickly (such as 100% to 50% in 20 mins).

Has anybody encountered similar issues ?
Any idea/suggestion on how to solve it ?

Thanks !!
