I know blown capacitors in electronics can cause all sorts of strange issues. This is only a hunch, and probably the last thing I can think of that I could try on my own.

My next recommendation was going to be that. To replace any capacitor you can find there. As far as I know it is not a usual problem on HP machines, but the aging of electrolytic capacitors is one of the most usual causes of failure in electronic equipment. Other capacitor types are less prone to failure, but the cost of them is so low, that it worths to try...
