padgett Posted January 9, 2002 Share Posted January 9, 2002 If it always comes back, you have an intermittant wiring problem. Do you need to reset the clock each time ? Any trouble codes (see FAQ on <A HREF="http://www.reatta.net" TARGET=_blank>http://www.reatta.net</A> for how to retrieve)?<P>Probably just a bad connection (worse when it rains ?) but finding it could be difficult/time consuming.

Guest Posted January 9, 2002 Share Posted January 9, 2002 thanks for responding.No the clock doesn't need to be reset each time.The condition shows no correlation to weather. The last few days it has been flicking off and coming back on within seconds. But usually it remains off for at least ten minutes. Link to comment Share on other sites More sharing options...
Barney Eaton Posted January 10, 2002 Share Posted January 10, 2002 I talked to a Reatta owner in Mass last week with a similar problem and would check the connections at the CRT and IPC. <P>If that doesn't fix the problem it may be a bad connection at the Central Power Supply or a power supply going bad.<P>The power supply is located behind the left side of the instrument panel.. should be a rectangular metal box.

I DONT DO MY OWN MECHANICAL WORK AND CANT FIND AN HONEST MECHANIC WHO DOES THIS KIND OF ELECTRICAL WORK. BUT I LOVE THE CAR AND DONT WANT TO SELL IT!

tcams76 Posted January 11, 2002 Share Posted January 11, 2002 Barney, my '89 touchscreen is giving me problems.<BR>Sometimes I get wiggly lines for about 5 min, other times nothing works to touch for 2/3 minutes then returns to normal.<BR>Do you have a number for a trade out service.

Barney Eaton Posted January 11, 2002 Share Posted January 11, 2002 If you feel the CRT is bad, the best prices are from Rex Service in Worth Ill.<BR>Call 708-448-5558 for more information and their shipping address.<P>I did some calling before the holidays and found Rex to have rebuild service for around $100. All the other "service locations" charge $200-$250 for the same service.<BR>Rex only business is CRT's. <P>If you need your radio, instrument cluster, cassette, or other GM electronics repaired, do a search on this site for the names of locations near you.

tcams76 Posted January 11, 2002 Share Posted January 11, 2002 I'm confused again is it my touchscreen or the controller which is the source of my problem?<BR>My screen has occasional wiggly lines and delayed reaction (2/3 min). Link to comment Share on other sites More sharing options...
Guest Posted January 12, 2002 Share Posted January 12, 2002 I have the same problem occassionally with the wiggle lines on the bottom 1/4 of my CRT screen. My Reatta is an '89 model also. Is there any companies that offer exchanges for the CRT? I'm not sure if the screen is failing or a loose connection somewhere... Link to comment Share on other sites More sharing options...

padgett Posted January 12, 2002 Author Share Posted January 12, 2002 A C553 and no B552 indicates a faulty power line to the CRTC (if both the BCM and the CRTC had lost power e.g. the battery was removed, you would get both). Are you losing the radio presets ?<P>FSM indicates that continual C553 without B552 is the result of a bad connection. So might try R&Ring the CRTC connectors.<P>Reset the code and see if they come back. Link to comment Share on other sites More sharing options...
tcams76 Posted January 12, 2002 Share Posted January 12, 2002 Bingo, I'm losing presets. Where are the C-codes found?<BR>thanks padgett: off topic I had my car buffed at a body shop yesterday, and used some of that Zaino's car polish today- shines like a new car now. I don't know what's in that stuff but it works like magic and is easy to apply and remove.<P>Drivin': the manual said for the rolling picture disconnect the CRT and connect tool <J-34914> to see if the test tool rolls, if so replace CRT, if the test tool does not roll check for open or short in CKT 723 or poor terminal contact.

tcams76 Posted January 12, 2002 Share Posted January 12, 2002 Part my message got deleted should read use test tool J34914. Link to comment Share on other sites More sharing options...
Guest Posted January 15, 2002 Share Posted January 15, 2002 Thanks TCams76. Based on your suggestions I think the problem is poor terminal contact because when I hit a large bump in the road, the CRT jumps back to normal. I'll investigate - where do you find the test tool J34914? Link to comment Share on other sites More sharing options...
Guest Posted January 15, 2002 Share Posted January 15, 2002 THANK YOU ANYWAY SKIP, BUT I HAVE A HUGE BOOK FULL OF SCHEMATICS. I AM AFRAID OF SCREWING IT UP WORSE IF I MESS WITH IT.<P>I WILL TRY THE PHONE NUMBER OF THE GUY IN ILL. Link to comment Share on other sites More sharing options...
Guest Posted January 17, 2002 Share Posted January 17, 2002 Hi Skip !<BR> I just tried to email you but my computer is misbehaving today. No luck with the mechanic in Worth IL. I may have misunderstood you-were you offering your help, or just your schematics? Please advise. I love this little car but I am getting frustrated. You may email me at COPPERSKIP709@YAHOO.COM<BR>Thank you....Carrie Link to comment Share on other sites More sharing options...
Guest Posted January 19, 2002 Share Posted January 19, 2002 I had the crt blinking problem several years ago, turned out to be the power supply Barney mentioned. Found the problem by accident, pulled the lower panel which exposed the power supply and accidently kicked the box while exiting the car and the dash blinked (big feet). From there I just tapped the box with the butt end of a screwdriver and was able to manipulate the display. Getting to the box is no big deal, pull the lower panel above the pedals, rectangular shiney aluminum box held in by 3 screws I think. part # for the testing tool was er' 11 Link to comment Share on other sites More sharing options...
