Hi guys,
I have a wierd problem. I have 13 boards (a mix of V3, V4 and V5 boards). One of the V3 boards started acting up today in the middle of a show. :'( It is the 8th board in the series. This board worked fine last year.
When I remove the cat 5 cable and run the tests, the lights turn on sequentially. Once I plug in the Cat5 cable, and power up the board, all the lights start flickering randomly - including the 7 segment display on the board. All the 3 7seg display do not display the channel numbers or the words PRG TST etc correctly during startup with the Cat5 cable plugged in. The mode button does not switch to test mode. When the cat5 Cable is removed and the power reset on the board, the board behaves normally. What could be wrong? Luckily I have a spare board for the show to go on... I am afraid if another one starts acting up, I am toast. Help needed.
All other boards are working fine - while still connected to the one that is playing up.
Dilip
Came back from work just now and the board is working like nothing was wrong.
It looks like the temperature has some affect on that board. It was baking in the sun till now.
(Some nights the temperature is around 33-34 F)
I will replace the 3.3V regulator, as soon as I can (over the weekend)
Thanks for your help.
