Might need a instrument cluster with bad LCD Gl1500

Some of you fine folks may be aware that my 1500 went under flood water along with my gas generators.
I got the generators easily cleaned up and run fine so I decided to do the same for my wing.

I just can't bring myself to load it on a dump truck...I'm going to attempt to salvage it.
I have prepared and filled the engine/carbs with diesel so it should be OK but I'll bet my instrument cluster is toast.

When the time comes..months from now...I may be on the hunt for a complete instrument cluster...

Hoping that someone may have saved there's when they replaced it for a bad LCD display...Mines still good.

Not much worried about the radio stuff but I would need the gauges to work.

No panic..this is a side project...while I'm waiting for the wood to dry out.
I'll first try to get some electric working and get it cranked up...I figure if it has a heartbeat I can get the electric working..

Saw it on a U tube video. :D

Honestly, if it was working before, if it is cleaned and dried, it should work again. LCD's themselves are sealed, and the circuitry, once cleaned and dried properly, should work fine.

The only unknown is if there was power going to it when it was submerged. I know there's a clock in there, and it has power at all times - a miniscule amount. Is it enough to damage something when submerged? I have no idea. All bets are off about that one if it was powered when submerged. The clock is physically on the circuit boards on the back of the LCD.

The radio also has a tiny bit of power, to retain memory, so that may be in question as well.

If the LCD itself is OK, you might be able to get the circuit boards from someone with a damaged LCD, and transplant your LCD onto their circuit boards.

Using my LCD is the most I'll be able to salvage.from the display electronics.
The gauges can be cleaned and lubed if the PC boards are salvageable.
Your correct as I too have found.If the electronics can be flushed and dried quickly there's a 50/50 chance it will live.
However if there was any power applied to the circuit I've seen burn marks and rapid contact oxidation destroying the PC boards from electrolysis.

I expect the radio is toast...oh well.
The ECM and CCM are a sealed unit.I suspect there OK.
All the switches will have to be disassembled and cleaned too.
This really is going to be a wintertime project.
