Macintosh Performa 200 with a solid white screen

Alex

Hello

I am thinking of bidding on a Performa 200 whose symptom is a solid white screen.

Has anyone here come across this issue and is this enough to place a guess on what might be wrong with the machine?

Any info would be greatly appreciated.

Judging from the picture, does it appear there may have been tampering inside to adjust the display. My hunch tells me that the display goes too far near the edge. Am I wrong?

Many thanks

Performa 200 is a, hmmmm, Classic II. The video looks OK so its not the Analog Board as far as I can tell unless video brightness is too far gone. The small pic looks like the menu bar is up but looking at the large pic, it is not.

How much is it going for?

Does it "Bong" on Power Up?

With the Classic II, a recapping fixes most things on it but be prepared for broken/rotted traces. A recapping will not fix everything because of broken/rotted traces. They will need to be touched up and patched up. Various members can and do recap/logic board repairs, so you can talk to them. See Uniserver about how much it would cost, I consider him to be one of the best. Or you can discuss it with others here who did a recap on their boards.

With me, I 1/2 fixed a dead Classic II I found in the trash. Got video back with a recapping, but no sound. That's rotted traced for you. I just need to sit down and finish the repair.

 
Brightness is analog board/software controlled so a recapping there if pram reset does not work and motherboard recap at a minimum. Do it yourself and for about 25 dollars in caps and would probably good to go.

 
Thanks guys

Well I found out from the seller that it doesn't chime, he hears fans and disk activity and that it only has 2 of the rubber feet.

He also claims that the machine exhibited the white screen several years ago and has since been stored in a closet.

Is it worth considering?

I guess the rubber feet can be replaced easily correct?

Also, if it comes to a recap, is it easy to do? I guess it involves removing the old caps and replacing them with high quality new ones. Is there something special I should know or be able to do? I can solder but haven't done so in 20 years or so.

Would love to hear your honest opinion, feedback, advice.

Thanks once again.

There are some tiny caps on the motherboard that can be a pain but everything else is pretty easy only issue is the battery on the motherboard at this point. If he didn't pull it could be bad.

Are there photos of the logic board that point to those caps that need replacing, especially the small ones. I just want to know what might be involved. Also, does the step require the CRT to be discharged? I don't like the idea of getting near a display for discharging purposes, though I've done it before.

With respect to the battery, are they known to all blow or is this isolated to a particular brand of battery?

What do you guys think, is it still worth the risk?

Offtopic: Is it possible to get ethernet for this guy? I do have an Apple CD300 that I can use for data transfer installs I suppose. A joyful hobby :)

 
There used to be some but when site updated the images vanished.  Its not hard just snug against a few cable plugs.  The CRT is supposed to discharge on power down but there is no need to touch the crt to mess with these really.  The analog board can stay in and the logic board unplugs and slides right out.  

Brand of the battery doesn't really matter a whole lot, it just depends if the inside guts leaked out onto the motherboard.  Its been 20 years and if they don't say they did not know or want to look.

Gamble is yours, Ive gotten worse and made them work.

 
Thanks Macdrone

I may take the risk. I always wanted a compact Mac. It might be an interesting challenge. Ultimately I might ask an electronics engineer to see if caps or other parts need replacing. Battery will be replaced for sure. I'll keep you all posted if I win. Thanks so much guys, I do appreciate your input.

 
It is not that hard to recap a Classic II/Performa 200 logic board. The problem is that space is very tight and you might not get the iron in place to solder properly. But if you have the money, it would be better to send it to Uniserver, he has a hot air soldering station for this kind of work. He'll get that mad  puppy howling in no time! Discuss with him about repair, parts and shipping costs. I'm not discussing prices, but from what I seen and heard, he's done excellent work for the price he charged.

The Battery in Question is a red and white/silver battery with MAXELL on it. They tend to blow up and spill their battery acid and destroy boards from massive corrosion.  Other batteries do this as well, but not at the scale the MAXELLs do it on. Since the Mac IS DOA anyway, you should open the case remove the battery (regardless of name brand) and chuck it immediately if it has not corroded. When you get/repair the board, put in a new battery.

Good luck on the bidding.

 
Elfen is correct regarding the Maxell's relative to their counterparts from other brands. They are lovingly referred to as "bombs" in the vintage community since they are known for destroying more motherboards than absolutely any other brand.
