Default Picture upside-down on JVC roof mounted screen

I installed a JVC roof mounted screen in my car 2 days back. Till yesterday, it was working fine but today, when i switched it on, the image was displaying upside-down! Initially, it was showing no-signal, which i figured out how to fix because AV1 was selected and screen was plugged into AV2. Headunit is a pioneer.

This screen is an old model (which i recently bought from blueraven) - some 2 years old and i don't even know the model number. Please help me in fixing this issue.

Please help!!!!!!

Since you bought the screen from blueraven why not approach him for the fix?

The inversion is a soft setting. Check the settings menu. Somehow your unit must have got reset.

Go to Menu and then picture settings. You will find the setting there. Various options are offered, depending on how the screen is mounted.

There are just 4 options in the menu: brightness, contrast, saturation and source av1 or av2.

I changed my car battery today and since then, the picture is upside down. Should i try disconnecting and reconnecting the power?

But the default setting should be normal view when fixed on the roof...right? And this is how the image should be displayed once we reset to default?

If that is indeed the case (strange - do double check) -- then maybe there is a setting on the pioneer HU ?

Definitely the cause for this "soft setting" to get forgotten.

Reconnecting the power once again will probably not fix this issue.

The HU is DVH 5850 Pioneer. Do you have any idea where to look for external display settings?

No, the problem is not with the HU, which will always send the video out the right way up.

If there is no menu setting in the monitor, then check if there is a switch setting somewhere, which could have been disturbed.

oops I forgot to notice it is a JVC roof mounted monitor. Check behind the screen on along the side edges there whould a switch your car clear might have switched while cleaning. Look for Inverted Image Function in your manual.

There is just one switch which is for switching on the lights, thats it :-(. I bought this as a used thing and there was no manual with it.

Your monitor should have a settings button. click through it and explore all menu options. There you may find one called "invert/flip" etc.,

You could also visit the JVC site, identify your model with the help of the pictures there & download the manual.
The manual may help you with future problems too.

Issue resolved!

Image was upside down and apparently i could not find any way to get it right. So i did some basic DIY stuff.

Step 1: Remove the screen from the car
Step 2: Open the LCD screen casing
Step 3: Rotate the screen and put the casing back
Step 4: Install the screen back in the car.
That's it!

Tools used: nail filer and kitchen knife for unscrewing the casing, nail cutter for cutting the wires and a fork to open the smaller screws .
