So that little black connector with pins that goes to the main board has labels for each pin, so you need to mount all the boards back in place, black probe of the meter on the metal chassis, red probe of the meter is then used to measure the DC Voltage of each pin, report the readings to us.
DO NOT TOUCH ANYTHING in the HOT side of the circuit, do not touch the heatsinks.

"replaced yellow varistor TVR 10 471K03" That is MOV for surge protecion, it is not need for the circuit to operate, so put the original back in.

It is the 16V rating you have that that. if it is 'A' then get the 'A', not 'C' or anything else. Read the spec sheet to match what you have. Is it really P5KE16 'A'?

Thank you for the answer.
I am currently not at the place with my broken screen and all equipment. But i will post my findings, as soon as i get back in a few weeks.

Just got home. Thank you for the patience.

Unfortunately that would prevent me from taking the measurement. Boards are covered with metal plate that holds them in place. What i can do is place them inside the cover and connect them at least to them selves (not to the screen itself that is not possible, for the same reason as before + screen wiring is too short to connect it while being upside down for the measurement)

I made a picture.

Ok done

Correct.
I found one with almost same specs but slightly bigger case.

I fix 5 Acer AL2216W LCD monitor already, most problem same you had. I just replace the bad capacitor had swelled only is will working again.
if safe side you just replace 5 caps on inverter side only (not 120uF 450V & 2 small caps above big cap)

Hi Hoadle,
I came upon your post as I have an Acer AL2216W and you fixed 5 of the Acers. Unfortunately, this tread shows a different Delta DAC (don't know what the model is as the photos posted are fuzzy) but mine is different (DAC-19M009 Rev 01A). Does this DAC sound about right to you?
The electrolytic caps on the inverter side (7 caps out of 8) are bulging and 2 are leaking and I would like to replace them.
Sincerely,
John Graham

Like wrog says, Panasonic FC or FM are go choices as replacements. FM has better specs and are almost the same price if purchases through digikey. Replace all 8 caps, including the smaller ones as they are part of the startup circuit. I'm including ordering instructions, since it can be a little confusing if you never order them before.


Here's the best way to order from digikey:

1) Go to digikey.com

2) In the "parts search" window type: panasonic fm and select "GO" button

3) Under the Capacitor heading select "Aluminum"

4) The first two columns you see are capacitance and voltage. Highlight the value and voltage with your mouse and select the "Apply Filters" button

5) You'll see several selections available. Here's what to look for:


a) Look at the quantity available and minimum purchase. If "0" are available, then there's none to purchase. Some selections require a minimum purchase of a 1000 units, which you also don't want. I think you get the picture.

b) height and diameter. Measure the original caps and compare to what's listed.


6) If your value is out of stock, go back to the beginning and type in "panasonic fc" and go through the same process.

7) During the checkout process select USPS First Class shipping, since this will give the best ship rate.

EXCELLENT advice! I managed to get 6 of my 7 bulging (2 are leaking) capacitors Unfortunately, I don't know the value of one that I require as it is glued to the board and breaking the glue also stripped the capacitor values (uF) but left the voltage rating intact. I have the Delta DAC-19Moo9 Rev 01A and the capacitor is marked CE103 on the board.
Would you (or anyone on this forum) know what the value should be?
My apologies for not posting a photo of my board, but every time I do that, my post is "UNAPPROVED".
Sincerely,
John Graham

As a side note: My Acer AL2216W has a different PSU than what is depicted here in Post #1 and other attached photos - mine is the DAC-19M009 - see attached.
Anyone know why? (maybe over the years, Acer has upgraded to different Delta PSUs).
Sincerely,
John Graham.
