Damaged ft-8800 head

 

I managed to spill a drink onto my ft-8800 head and now it will not turn on and there is water visible under the display screen.

Is there any way to fix this or can I buy just a head to replace it?
 

I would try putting into a bag of rice. It might work, and save you a few bucks. The 8800 isn't made anymore, so it might be hard to find another head. Just my 2 cents.

I’ve dried out electronics simply by shaking them out then leaving them in an air-conditioned or dehumidified room overnight. The culprit in my case was rainwater. A drink other than water will have ?contaminants of course: sugar, oil, etc. that might mean fouling of contacts and corrosion of metal. Good luck!

I would call Yaesu and ask them for their advice. ?If you are technically inclined you may be able to wash the circuits in ‘distilled water’. It has to be distilled else dissolved minerals in the water can leave conductive paths. But check with Yaesu before doing anything.?

A lot of printed circuit assemblies are washed in water these days to remove the water soluble fluxes used in vapor phase ovens used to flow the solder during assembly. But the unit has to be dried. Yaesu should be able to tell you if your radio can be disassembled and washed in a bath to remove the drink contaminants.?

Hi Steven,

Your best bet is to call Yaesu USA at 714-827-7600 and ask.

DO NOT TURN IT ON.?

You definitely don’t want to power it on while there are contaminates in the head units. That will cause accelerated corrosion. You should clean with, ideally, de-ionized water, then use isopropyl alcohol to clean off the circuit board. The alcohol will evaporate much better than the water by itself. Then you want to dry the circuit board by letting it dry for a few days maybe.?

The plastic parts you can wash with soap and water, when it is taken apart. Just make sure it is complete dry before putting it back together.?

Ok... I took the cover off the back, but no water came out..? I placed it face down for several days to let it dry out.. When do I hook it back up and turn it on ..

If the drink that you spilled was not water by itself you have to clean it. If it was soda the sugar and acid on the soda will get more concentrated and cause corrosion. Do not turn it on until it is cleaned. At the very least clean using small amounts of water on a q-tip. The best thing you can find quickly would be distilled water, is there are any stains or dried residue you have to clean it up. If there was sugar in the drink, you need to get it out, water will dissolve sugar. Alcohol won’t. So first use water, the. Use isopropyl alcohol, if you have some high concentration like %90 or higher it’s good to use that after the water, go over the same areas that the stains were and let it dry.?

?Once the electronics are cleaned make sure the plastic parts of the head assembly are clean of any stains or dried residue.?

Once you are sure everything is clean and dry. You can use canned air like keyboard duster to get and water out that has been hiding. Then reassemble.

A video on cleaning, I think he uses an ultrasonic cleaner so not everything may be relevant. But it will explain why you want to clean this way and what can happen if the gunk is not removed. Simply drying is not enough. Please pardon his colorful metaphors.?
