#Optoma projector fan locked how to

Then clean mother board of residue with alcohol. Wondering if I should just order a fan and determine which one is failing and replace it.

Noticed a little white staining on the board when I opened her up and a very faint amount of white residue on board and very light crust on a few piece of metal. Have had a few floods down there and high humidity. I have an Optoma HD33 and after 3 years just got fan failure. Hey guys, anymore info on this? Did any of you remedy the problem. I ended up having to find a replacement plug to use and rewire onto the cable. I would get this error when the plug for the ballast/lamp fan cable was a bit worn. And if that fails, then it probably is a controller issue.

So, if you have ensured (very important so you don't waste your time) that the fans are still running, you need to make sure the third wire on each is not frayed and still carries a current from one end to the other. In the hd70 a fan failure means a failure to read the fan power or rpm (i am not sure which the fan is manufactured to do, i'd assume rpm for proper cooling) given by a third wire on the fans cable. Visually, i don't mean listen or anything like that, but you need to verify if each is actually spinning. What you need to do is start the projector up and see what fan doesn't start. I don't recall any other fans existing beyond those two, but i could be wrong. Its been a while since i've been in an hd70, but i remember that there are two fans dedicated to cooling the lamp, one is a blower type fan and is buried a bit under the main board, and then there is another fan, the regular type, toward the ballast blowing onto the lamp also. If someone, anyone, could please give me some insight on this issue it would be GREATLY appreciated! This is truely my favorite item in my home and I feel naked without it The bottom line is I'm out of warranty and I want to fix this myself due to the fact that I'm low on funds at the moment.

It may be the controller board but I can't find any info on how to get that part or how much it costs, or if its even truely the problem. I don't believe that it is the actual fans (there are two inside, both sunon fans) that are causing the problem, nor do I think it is overheating because I have taken the front cover off and put a huge fan next to the front and when doing so the PJ runs almost cool. I have taken it apart several times in an attempt to clean it out and the problem still persists. I can turn on the PJ and after about 15 minutes the message pops up and the PJ turns itself off along with the red light turning on. I've had my HD70 for 4 months and about 4 weeks ago I got a 'fan failure' message and it hasn't worked correctly since.
