"TOKYO BY NIGHT"

Kaverin samanlaisessa on "samat" viat, eli vilkku näyttäis olevan päällä koko ajan, ja mitä milloinkin välähtää. Käynyt huollossakin jossa eivät pystyneet lokalisoimaan vikaa. Luulisi mittariston vaihdon auttavan kuitenkin...

Vie mittaristo radion korjaus firmaan tinattavaksi.Auttoi ainaski mulla.

Tämä neuvo tulee tietysti kovasti paljon myöhässä, mutta mutta auttoi ainakin omassa 200:ssa. Tapoja on parikin, samalla vaivalla hoidat molemmat pois päiväjärjestyksestä. Piirikorttien pitäisi olla suhtsamanlaiset ja tuo valojen välkkyminen on on varsin tavallista tuon korityypin audeissa. Oheinen leike on tosin "toisella" kotimaisella.

"Fixing the OK system check display
On my '91 200q; when the car was started the "OK" symbol would occasionally come up as a series of lines. It also happened when the cooling fan circuit lost the fused ground and the car overheated; I couldn't tell what was alarming, only that it was red. Sometimes a firm slap on the dash over the display would fix it, or shutting the car off and on again.
When I developed further problems (putting on the high beams illuminated the turn signal indicators, the turn signals flashed the high beam indicator and the opposite signal indicator, the dash lights started going off & on, etc.) I suspected a ground fault & pulled the instrument panel.
Sure enough, there was an intermittent ground on the board. There are two ground clips which look like computer board jumper blocks. The pins which engage in these allow the circuit board and the main instrument cluster to be seperated. The spring contacts inside the jumper blocks had relaxed and were making an intermittent ground. I built up the pin diameter with solder and voila! - problem solved. I haven't had the problem with the warning display since - here's hoping!

The intermittent dashboard on my 200 has been driving me nuts for four years. Finally I said enough is enough and completely resoldered the main PC board. This is a shotgun "approach", but instead of scrutinising every solder joint for cracks I found out over the years of troubleshooting various electronic equipment that touching up all of them with a soldering pencil is a far more reliable way, and a faster one too.
Net result: no_more_friggin' hieroglyphic pictograms in place of diagnostic symbols in the main computer window. A number of listers had the same problem with their 200's and I don't recall anyone finding a remedy. So here it is: just solder every joint on the board. Make sure you have a good thermostatically controlled soldering pencil. Please, don't use those $4.99 Radio Shock specials! I use a programmable Weller with a 3/32 chisel-shaped Ni-plated tip. "
