 Bigger Bigger  Smaller Smaller  Reset Reset

Tried the test on an UNO nothing echoed back from serial monitor, when reset is pressed LED 13 (on board) blinks/flashes a few times after jumpers removed. Is the conclusion to be drawn the the board is dead or is there another soultion?

When you try to upload a sketch to the board does the on-board LED flash a few times?

Do you have the correct board selected (Tools menu)?

Hi, yes (for my board Uno and OS) I have the correct Board selected under Tools > Board > Uno, also under Tools > Serial Port > COM 3 is selected, I check that prior to verify/uploading code. This has worked well for over a year now no problems until now?

The TX and RX pins should "idle" high.  Do you have a voltmeter?  If you do, with the board powered, carefully check the voltage on TX and RX.  Do they both measure 5 volts?
