Greetings All,
I need advise on another monitor project that requires capacitor replacement and need to make sure I'm ordering the correct parts and to confirm I'm looking at the correct problem/diagnosis.
Monitor: BenQ Q22W6
Board Ver: 4H.03V02.A02
Problem: A few days ago the monitor (using as TV now) went blank and the green signal light stayed on. The monitors menu and picture would pop up for a second or two and then go blank. After investigation when you hold a flashlight up to the screen you can see the picture in the background. So I suspect back-light inverter or power issue.
Diagnosis: After disassembly I located 5 bulging caps on the power side and I'm currently in the process of getting them (doing all caps) but wanted to confirm that what I'm ordering is correct.
Original Caps:
Elite 470uf 35V (4 bulging)
Elite 220uf 25v (1 bulging)
FDAI CD112A 47uf 50v (none ) <-------- This is the one I'm curious about as it's replacement looks smaller (in can size) then the original.
Replacement Caps:
Panasonic 470uf 35v https://www.digikey.com/product-deta...0301-ND/266310
Panasonic 220uf 25v https://www.digikey.com/product-deta...3CT-ND/6109541
Panasonic 47uf 50v https://www.digikey.com/product-deta...0321-ND/266330
Back in 2013 I used Panasonic to replace bad caps in a Hanns-G HG281D with help from you all and that monitor is still up and going strong. Please let me know if these will be fine or recommend another brand in that price range and also can these bad caps cause the issue I'm looking at? (Hopefully so...lol)
Thanks much!!

Also went over the boards with a magnifying glass and saw nothing blown that could indicate another issue though components were not tested yet.
