Service menu back light does not come on

Main board fault. Contact the authorized service center for Sony.

on some of the vehicles, you turn the ignition key on, but do not start the engine, then press the accelerator to the floor 3 times within 10 seconds, do this pretty fast, then turn key off, then turn key back on again , but do not start, look and see if the maintenance / service light has went out.

You could have a back-light problem and it could be a faulty inverter board or a CCFL lamp.

That is a Jet Heat error. Most likely a bad print head. Could be the electronics module.
Either the print head heater has failed, or the supply voltage to the print head heater.
Either one is very expensive to replace.

The "Perform Service" Is supposed to alert you that you are due for an oil change, it will light up every 6000 miles. If you get your Oil Changed at a Dealer, they will clear it for you, otherwise you can clear it manually by:

With the key in position 1, hit the odometer reset button on the left on the cluster 3 times in a row. The cluster should beep once. scroll through the multifunction display with the page buttons until the display shows the onboard voltage screen. It will say something like "UB: 12.2 V" scroll threw this menu with with the up/down until you reach the "service menu" page. scroll down to "confirmation" press +, confirm full service with +. Wait till it says service confirmed. cycle the key off and then back on to position 2. Scroll to the normal service menu where it normally says how many days or miles till next service. If the service was reset correctly, it will say "service display not possible" for a few minutes while it recalculates. You must cycle the key off and back on before it will back out of the onboard diagnostic mode. If you dont back out, the esp/abs/bas lights will illuminate when the car is started

Hey guys, had the same problem. Found this solution on the web. Worked for me.

JVC HDMI Port Fix

Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord. Reconnect the power cord, turn the TV on, and the HDMI port is reenabled.


Here’s how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.

This should work.
