Why is the display screen blank?

Sounds like you fried something that was the first thing I thought of after reading this. check all the connectors on the radio see if there is any burnt marks on it anywhere check fuses and the connectors where the face plate goes on to see if it is dirty or damaged

This is how to reset the receiver to factory default- not sure if it is the same reset you would do for an amp error:

Resetting the system
Use this procedure to reset all the receiver's settings to
the factory default. Use the front panel controls to do this.
1 Switch the receiver into standby.
2 While holding down the front panel STEREO/A.L.C
button, press and hold
u STANDBY/ON for about two
The display shows RESET?.
3 Press the front panel AUTO SURR/STREAM DIRECT
The display shows OK.
4 Press HOME THX to confirm.
OK appears in the display to indicate that the receiver
has been reset to the factory default settings.
Note that all settings will be saved, even if the
receiver is unplugged.

Unfortunately, amp errors are usually not fixable and require you to bring the receiver on for repairs or just buy a new receiver.

THANK YOU AGAIN SO MUCH! I basically got through the 1st step or so and the thing came right back on like nothing had ever happened. Although, I think what ended up working for me was actually pressing and holding the STANDBY/ON button with the AUTO SURR/STREAM DIRECT button together for a few seconds....I didn't have to reset to factory settings, nor did I have to do step 3 or 4.

Now the receiver is working just fine like nothing ever happened. All of the input AND output speaker channels all seem to be functioning normally and in peak form, and I've made sure that I have the area around the receiver well ventilated. So....thank you, again...for getting back to where I really wanted to be without having to go through the hassles of disconnecting everything and having it serviced with possible $ and time expenses.

Kenwood kdc-mp632u display is blank

Possible that the display is faulty or there is a fault in the power line. Also check if the strip that connects to the display is faulty. If the unit works perfectly except for the display then the fault is only with the panel and a voltage check on the panel will confirm the loss .Use a multimeter to test the voltage and also check on the tracks for continuity.

Hi, I have a 2003 Chevy Venture and my 2 year old did something to the CD player and now it won't play and there is a disc stuck inside. There is nothing on the display like "LOCKED" or...

You have to take it apart. look for screws on the panel around the stereo. pull it apart as much as you can. Inside the cd player will likely be a peanut butter sandwich.

CD player and everything works fine but there is no display .....

Well, my display went out earlier this week. Took it apart and found out that the LCD on the 501dpx was burnt out. I also found out all we have to do is replace the whole faceplate instead of the system

Alpine cda7969r display problem

Hi trinder,
I fixed my Alpine TDA-7563 with the same problem. My display was completely blank everything else worked. After checking that the LCD display is getting power and everything else in the face that I can think of, I thought maybe the rubber LCD contacts were squeezed down or something and not making proper contact, so I just pushed it back onto the board and pressed.
This was at night, so I had an external lamp and noticed to my delight that the display was in fact working, nothing is wrong with it.
I am embarrased to say that as a technician I forgot that an LCD display needs a backlight, duh.
So a simple connectivity test on the 2 lamps shows that they are both blown.
I have to source them at my local electronics store, I measured the power supply to them as 12Volts, so it is just a matter of getting ones with the right dimensions and bright enough.
Hope you have the same problem, then it will be an easy fix for you.
Good luck,

Display stopped working

My Alpine CDA-7842 works fine from a functional point of view but the display (readout) had stopped working. All the lights on the display work but the actual readout is blank. At first the readout would intermittently work now it's completely dead. Any assistance would be greatly appreciated.
