Asus VE205 .... 2seconds to black

Re: Asus VE205 .... 2seconds to black

Looking at pictures and telling you what pins to test is something i am not very good at.
It is exceptionally difficult with the pictures you provided, a better picture would be one straight down showing the entire board, please try to use natural lighting.
I THINK the secondary's are you're numbered pins 1 and 3 and numbers 2 and 8

transformer tests: (see enclosed pic for labeling)

1 to 2: 0.448 Kohm
1 to 3,4,5,6,7,8: open
3 to 4: 0.3 to 0.4ohm
3 to 5: 0.3 to 0.4ohm
3 to 6: 0.3 to 0.4ohm
3 to 4: 0.3 to 0.4ohm
3 to 7: 0.3 to 0.4ohm
3 to 8: 0.3 to 0.4ohm


NOt sure if the above readings are good or bad for transformer



IC: alphaomega 4614
https://cdn.badcaps-static.com/pdfs/...0e94bf963c.pdf

1 to 8: 3meg ohm
2 to 8: 3meg ohm
3 to 8: 3meg ohm
4 to 8: 3meg ohm
1 to 2: 10kohm
3 to 4: 5kohm

Not sure if these are good readings.....i think so but not sure


thoughts?

It's beginning to sound like 'two seconds to black'.

Re: Asus VE205 .... 2seconds to black

when i first tried the monitor it was hooked to a working computer. the screen would flash and then go out. for the led test i reported on previously it was not hooked to a wokring computer. i will connect it and then report back.

Re: Asus VE205 .... 2seconds to black

i put the lcd back together enough to check the led.

When i power the monitor on the led turns on and is a blue color. I see a flash ....i can see image on screen.........it goes away almost instantly........once it goes away the blue led turns "orange" but stays on it does not go out.

does this answer the question?

To a certain extent. It says the power supply isn't shutting down. Is the monitor hooked to a working computer?

Re: Asus VE205 .... 2seconds to black

It's really simple - one of the first tests should be to note if the power LED stays on when the screen goes black. If it does, that suggests 'two seconds to black'. If it does not, it suggests a problem with the signal card.

Re: Asus VE205 .... 2seconds to black

I know the led light turned on "blue" but i am not sure if it stayed on the entire time. THe led light on this lcd is in a weird position.

I have the monitor apart right now but i need to put it back together to test if the led light let me know. Again, i know the light came on because i commented on the "Blue LED" light looked nice.

Re: Asus VE205 .... 2seconds to black

Hi, its been a while since i did any kind of repairs..........but a neighbor has a monitor that is not working and they asked me to take a look at it.

its an ASUS VE205. You turn it on and it onlly stays on for about 2 seconds.

I have taken pictures of the boards. I took front and back pics of the power supply/ inverter board.

Any ideas? The caps look ok to me.......but i know that sometimes "looks" are not every thing.

Does the power light stay on?
