This thread is of a specific model.If it's your unit, post a pic set of the boards and cap info and we'll go from there.

What EGuevarae said. And for Faraday's sake, use some punctuation. Unreadable posts often aren't read.

Read?
As a matter of fact, I tend to read posts aloud to practice my English (2nd language) and see where punctuation can be inserted and such,so I can both try to help, learn and also improve my language.... you should try to read it....

Hello,although this post was started several years ago, it still keeps alive, so, after reading the whole tread, I think I can help a little.
When trying to fix an ACER 2017, I used this dac-19m005 datasheet I found on the web.

Here you can see schematics and components. Although it is a different LCD model, is has the same power board: DAC-19M005 CF REV: 00A, (plus it has just DUB conector, no DVI, but still the same board too), so: same problems and same fixes, I guest.
After recapping all (same 2 bulged caps as every faulty board), I can see images on the screen but no backlight. You only can see it taking a light close to the screen ( I didn´t read anybody in this situation, everybody has no light but nobody has mentioned about dark images with no backlight)
All the fuses on the backside are OK but I can see a damage transistor: Q204, on the backside, right close to the F200 4A fuse, so probably this is what I need to fix.
According to Kahless (on post #299 and # 301) and billy 66 ( #320) I can see Q2004 burnt ( probably that´s because F200 fuse didn´t blew up), but I checked R210 and I got about 11 Ohm, so I think it´s Ok. Anyway, I ordered replacements for the whole components:Q204,Q208 and R210.
I´ll post the results when I get it working here or in a new thread refering ACER 2017 (only DUB, no DVI conector)
Thanks
