My Rapsberry Pi 1 is damaged. The Broadcom chip gets very hot and only the red LED glows with green LED blinking randomly.What should I do with the Raspberry PI.
As mentioned in the comments for your question I suggest using a power supply for the pi like a phone charger which plugs into the wall socket. This should stop the under-power problems you are having. This may get the SD card working and you may get an image on the screen. If nothing appears on the screen first check the screen input otherwise the SD card may be corrupted and needs to be re-flashed.
Other options include trying the SD card in another pi which is known to be working to test if the card is corrupted. If it boots then the problem lies in the power supply. If it doesn't the problem is with the SD card.
That may be a stupid question, but did you disconnect everything from your Pi? I remember fiddling with one of mine "punch bag" Pi when it was on, shorting pins by mistake and it just shuts down and plays dead (on board LEDs suggesting that everything is A-OK) As soon as I de-shorted it - came back alive as if nothing happened. Try to power it on with just a screen plugged in.
Is the red LED on permanently? That usually denotes a power issue. I'd try a different power source. It may also be the case that the SD card is corrupted (this can be caused by bad power supplies), I'd reflash your OS on a new sd card too.

3This is just wrong. The red led being on constantly is normal; on some models if it intermittently goes out that indicates insufficient power. Further, the red led does not indicate anything about the state of the SD card, although red on/green off on a model 1 would indicate the SD card is invalid or missing (because the green led is out). The green led blinking intermittently (as per the question) indicates the SD card is valid and in use. – goldilocks♦ Jul 25 '16 at 13:51

- sounds like an operational pi to me – Jaromanda X Apr 25 '16 at 4:05
