Combo acting strange...Little Help

I would like to get some knowledgeable opinions. I have had a few combo drives and when they were done they were done. Anyhow it’s a TSST CDW/DVD TS-H492A…it’s actually been fine up till recently. I noticed that it was taking longer and longer to load a CD-DVD and then I noticed that it would act like it was trying to read something when it was empty…I mean lights flashing the whole bit. I thought about trying to reflash it first, but it has one of those friggin HP firmwares HP03. Any ideas would be greatly appreciated…I have had burners do this when the flash didn’t work right.
