I think it'* on vacation...hope it comes back soon...

No display anymore on the HU. No time, no radio station, no nuttin'. Tape and radio still work great with no change.

OK, so here'* the scoop. Last Fall, Don and I popped in a stock tape player w/equalizer HU in my SE to replace the poorly working original tape player HU. In addition to losing the signal quality in the right channel, the old HU display had begun to fail.

Now the Display on this one is gone completely. My wife, Liz, drives the car daily and told me last night that the display had begun to go screwy a couple months ago, on a sometimes basis. It would come up all chinese characters when first powered up, the eventually display time and channels correctly. It started getting worse and worse and as of yesterday, quite displaying anything at all. For some reason, she didn't tell me about it until last night...

Like said, the rest of the unit works fine.

Among others I have, there are these questions:

1. Is there a specific pinout or wire that controls power to just the display?

2. If so, which one is it and how do I fix it? Understand that I have never paid much attention to audio, so keep it simple for stupid, if you please.

3. Has anyone else ever experienced this failure mode?

The light bulb doesn't work?

You can replace the light bulb. (being the king of search..look for Travis and Andrew for the part numbers)

I could be wrong, but I din't think it'* a light bulb that I'm talking about. I mean that the digital readout started to go crazy on start up. Initialy creating weird characters , then setling in to read the correct time and or station. That should be some sort of LEDs or something, NO?

This is not the backlighting.

Edit:
It isn't the backlight I'm talking about. It'* the LCD. I think it has to do with power supply. At least that'* what the symptoms seemed like.

Here'* a pic of the HU I have:

Just wanted to bump this while all you electronic geeks are here. My original posts were before anybody was on.

Can ya help me?

I don't believe that the HU itself if entering failure mode, only because there'* been no reduction in the music quality, functions, volume, etc. It seems to be only affecting the LED display.

I know that there are a few folks on here that have dissected the HUs and know their functioning and pin-outs.

I had sort of hoped that it was maybe an intermittent, going on permanent, short or something to just one supply wire or or circuit. It'* probably wishful thinking, but...

K.

I'll check and get back to ya.

I'm 99% sure that'* my old HU that I sold to Don for ~$10 a couple years ago!

I sold it so cheap because the display would get jumbled up in my 99 (and because I wanted a CD player).

Mike, i played this game with the GF'* GP GT. she had a 2 band CD and we swapped in a 7band CD. put it in and NO display. I took the bulb from behind the display of the known good one and swapped it in to the 7 Band. Now the 7 band works and you can always see the display
