<div id=AOLMsgPart_1_e450627f-90fc-4cd2-aeee-7ca15fdd3bfa><FONT color=black size=2 face=arial>I have an ID-5001 Weather Computer with the fluorescent display bulb that won't light. I built the unit in 2008 from a new kit and it has functioned perfectly for 2 years. The replacement bulb I purchased will not light either. All other data and functions are working fine. I unplugged the socket that feeds the fluorescent bulb sockets because I noticed that the bracket (heat sink) coming off Q307 (Part # 417-856) a MJE5979 transistor was getting extremely hot while the other bracket from transistor Q302 remained cool. I feel I may have a bad component in the lighting/dimming circuit on the power supply board but I don't know where to start. I know that historically, this fluorescent display was problematic and I really do not want to convert to LED's. Any ideas as to what commonly goes bad on these? As I say verything else works fine.</FONT></div>
