20" Apple LCD blinking power light - 06/27/11 08:57 AM

OK.. So I get up today and no picture on the screen connected to my MP . I see 1 short,1long and 1 short.

I brought it to work and plugged it into a different power adapter on my MBP and it does the same thing.
Model A1081

Inverter board?

This is a 20" matte screen that I really want to save. You can't buy these anymore....

I should be doing other stuff, but duty calls. smirk

Is it this monitor? The aluminum 20", DVI connector not ADC?

If so with the price of the inverter board we'll want to make sure that you can return it if it's not the problem. Also this site is always more expensive.

Yes, the model with DVI and metal bezel/white sides.

So you think inverter board also? I'm going to scout around to find a cheaper one.

Also, do you have the PDF for doing this repair?

Probably the inverter, the power supply is always the weak spot. I would make sure that they have a return policy wherever you get it though in case I'm, uhh, wrong.

It would probably be a 10-20% fee but it beats eating the whole cost at that price.

I would pull it apart and see what the board looks like first. I don't think I have any manuals for the aluminum models, I'll see what I can find unless you come up with one first.

According to this they look different. I may have the wrong monitor chosen though.

You are correct. The one linked to is the main board. I tore the unit down just to see what was what. Frikkin Apple/Chinese Origami mofos!! The unit splits at the bottom but not at the top... you have to hold the bottom open with pressure and slide the unit out while feeding the power cable thru the slot.
Now I can see if there are any loose connection or anything else that may be causing the problem. I thought I would check before ordering the part and also visually match the part with what I order.
Thanks for your help.

OK.. I fixed it with a tiny sliver of paper. laugh
Please read this thread starting from at least page 4 and go until the end. You can see people using this paper fix right up until a few days ago.
So, after reading the thread... should I go ahead with a replacement inverter board? Or the main board? Or just use the paper trick...lol.. and wait till my house catches fire.
Or the 150w power adapter...?

Ugh.
