Problems with 2009 VLX Malivew screen?

Recommended Posts

Fish209

I have a 2009 Wakesetter VLX with the Maliview screen (running vA16). I've seen on here that people have been having issues with the screen on Maibu's of this year randomly turning on and off.

I just got the boat this winter and have only been on the water 4 times. This first couple times went fine with no screen issues. I went out yesterday and the screen took a couple minutes before turning on at all. Once it did turn on a few minutes after starting the boat, it worked fine the entire time I had the boat out. When I took the boat out today, my screen was worse. For the first 20-30 minutes this morning, my screen was all wavy (see YouTube video below):

I tried shutting down the engine, turning it back on. I also tried completely shutting the battery power to the boat and turning that back on. No matter what I tried, the screen was like what is seen in the video...all wavy.

 

Luckily, after about 20-30 minutes it started to clear up a bit. Just enough to see what is on the screen, but still a little bit wavy. Then after another 10 minutes or so, it cleared all the way up and started working perfectly fine. I had the boat out another hour or so and the screen worked flawlessly the rest of the trip. After the boat was off for about 5 hours, I went and checked the screen. This time, the screen started right up with no issues at all.

 

I looked behind the screen to see if anything might be loose, but it doesn't appear to be a simple check (see attached image of under the dash). The connections I could easily check appeared to be tight. Would the problem I am having likely be a loose connection? Or would it likely be something else?

 

Could it be a temperature thing? The other times I took the boat out, it was later in the day (and warmer). Today was a little cooler in the morning and once it warned up a bit, it started working just fine.

 

How would you go about addressing this? I'd hate to have a big day planned and the screen ruin the entire day!

 

Thanks!!!

Anyone have any ideas what could be causing this wavy screen? What should I try to see about fixing it?

 

Thanks!

Possible fix if anyone is running into the same issue:

I stopped into a Malibu dealer close to me and talked with a service tech. As soon as I started to describe the issue, he immediately said it was likely a low battery. He said if the battery is a little low, the boat can still start up fine, but the screen might not have enough power to run correctly. He said he's run into that before and just making sure the batteries are charged fixes the issue.

 

He also said a lot of people (including me) are under the assumption when the battery perko switched is turned off, the batteries are completely shut down. This isn't the case and the do drain over time if not charged. He suggested just leaving a trickle charger plugged in when the boat is not in use.

 

This makes sense as I do not know how old these batteries are. They came with the boat when I purchased in this past Winter. I did charge them (with a trickle charger) when I got it, and again before I put it in the water. This would likely explain why the screen worked fine the first couple times I took it out (shortly after a full charge), then had the recent issues (possibly once the battery was drained a little after the boat sat for a while before I took it out again).

 

It also likely explains why the problem only presents itself when I first start the boat. After a period of time (maybe after the battery charges enough), the screen starts to work fine and I no longer have any issues the rest of my day on the water.

 

If anyone searches the forum with a similar problem and comes across this thread, try to make sure your battery is fully charged.

This is why I always recommend an onboard battery charger. Just plug the boat in when you get home and you always have fully charged batteries when you head to the lake. So many boats get put away with partially charged batteries, then underperform next trip out. Especially if you park in a cove and play stereo at the end of the day.  Rarely does the drive to the ramp charge the batts all the he way up.

I'm new to boating so this was a good thing to learn early on. I live on the water so my boat is on a lift during the season. Now I'll make sure to always plug in the trickle charger each time I end a trip out on the water.

 

I'm sure there's tons more that I don't know yet :)

Bummer. The battery is not my problem. I am back to thinking this is a loose connection somewhere.

 

I took the boat out today for a couple hours and the screen never started working. It was just a blank screen for the first couple hours. Then in some rough water, the screen started to show some life and get all wavy. When I would hit the top of the dash, the screen would change. Each time I would bump the dash or push on the screen itself the wavy screen would change and almost come into focus.

 

The functionality actually works just fine. When the screen was almost in focus, I could use the buttons to switch screens, set rider presets, etc...all just fine. It's just the display is not showing some of the time and not showing clearly other times. It sure sounds like a loose connection to me. Does anyone know where the connection to the display screen is (from the above attached picture of underneath my dash)? I don't want to go messing around with a bunch of wires if I know which specific one I should check to make sure its got a good tight connection.

 

Thanks!

Between the backside center mass of the Malivue and the dreaded POS black box (RFX-3000 on my ‘10) is a blue RCA cable that is the actual screen cable between the 2. It has clear screw on cable end caps to secure the cable to the heads. I would check the cable connection for the blue cable at the Black box, behind the amp board, to ensure it is seated into the Malivue screen receptacle. I couldn't count the hours I spent diagnosing, strain relieving, soldering and other wise screwing with that damn thing to make sure I had good connections for the radio, Malivue etc... It possibly could be loose on the backside of the Malivue, but that is highly unlikely as that end felt like it was inserted with a bearing press when I was messing with mine. Goodman luck. Bill

Thank you wdr!! If it's not a loose connection, any idea what might be causing this?

A low voltage issue will cause dash/screen issues but mostly MUX issues in my experience. What you describe sounds like the blue cable. I had ALL kinds of other issues with the connections on the BB for the radio and the MR-55 remote in the dash. That was isolated to the radio and dash remote functions though. Short of a bad or loose cable connection I would “guess” the screen, but I think that is unlikely. The screen really has no function except as a TV. The left and right push buttons have their own ports, cables and connections on the back of the respective sides of the screen. The tach and speedo are the same as well. The MUX if so equipped are run through the Viper and aren’t connected directly to the screen. A quick tell would be to power up the Malivue and smack the amp board. In this situation this is the best diagnostic tool you have for that POC. Good luck.

I messaged the old owner of the boat asking if he ever had any issues with the screen and he let me know the blue wire did come loose one time. He made sure it was a good connection and didn't have the issue again. This and wdr idea of the loose blue wire makes me really think that is the problem.

 

Problem is, where is this darn blue wire? I see a couple really thin blue wires that all seem like they have good connections to what I can feel. All the wires exposed when I look under the dash are zip tied together tightly so I can easily access any of them individually. I easily removed the black Medallion box cover which only really exposed the fuses. Is the connection at the end of the blue wire I'm looking for inside this box in the attached image under the dash (where all the fuses are)?

 

What blue wire should I be looking for and where is the connection I should be checking? How can I access where it connects to the back of the screen?

 

Thanks!!!

I reached out to previous owner that I purchased the boat from and he helped out. He let me know he had this happen to him and it took him a while to figure it out, but eventually did. It was a loose connection.

 

Here's what worked for me if anyone else has this issue:

It was a blue wire under the dash. The AV cable that goes into the blue box (pictured) towards the bow when you are under the dash. Make sure that video cable is plugged in securely. Then follow it all the way back up the back of the dash to where it connects behind the screen. Make sure that connection is secure also. Both mine appeared okay, but after wiggling and push both ends in, the screen is now working fine.

Update (in case anyone searches with a similar issue):

The screen worked for a bit after my last attempt to make sure all the cables were tight and secure. Then it just went completely blue and never changed no matter what I tried. It was just a solid blue screen. I took it in and they initially thought the entire screen needed to be replaced. They ordered a new screen and after putting it in, the screen was still just solid blue. They returned the new screen and talked directly with a Malibu technician. The Malibu tech told him to try replacing the RCA Audio/Video cable.

 

I purchased an $8 Cable and wouldn't you know it...that seems to have been the problem! My blue screen is gone and I can see a fully functioning screen for the first time in months.

 

So, if anyone has similar issues with their MaliView screen, definitely try replacing the RCA Audio/Video Cables first!!!! Easy and CHEAP fix!!!!!
