Re: I-Inc IF281D Display Problem
Also i forgot to mention i also plugged the inverter board alone with the other boards minus the t-con and it powered on for about 20mins, then i just unplugged it slightly angry and very confused.Leave a comment:

Re: I-Inc IF281D Display Problem
I ran a volt test on the monitor today hooking up the video/signal board with the powerbaord and control panel. i couldn't get monitor to power off for me with just these 2 boards connected. I did how test the 5vsb on the signal card and it seemed fine. i tested it by turn the tv on and off with the power button.Leave a comment:

Re: I-Inc IF281D Display Problem
I wouldn't know because i've never tried a test like that yet. I will test the monitor tomorrow to see if i get a drop in voltage. i'm assuming i need to have everything hooked up but be able to take readings while turning the monitor on correct?Leave a comment:

Re: I-Inc IF281D Display Problem
To answer your question bill i powered the monitor on first blue light came on then it went into standby (Orange light). Then i plugged my HDMI into the monitor and powered on the playstation. The monitor reacted and the blue light came back on shortly after followed by a picture.
After 2 minutes of working perfectly with sound it shut off completely. No power light no orange light, no blue light ,no light at all on the bottom right corner. Like someone just unplugged it.
I tried turning it back on but it wouldn't...Last edited by AloofOne; 01-16-2012, 03:00 PM.Leave a comment:

Re: I-Inc IF281D Display Problem
So i was looking over the power board and noticed a cracked solder joint so i decided to attempt a repair.
After about 20 mins practicing on a junk board i felt confident resoldering the joint. After resoldering i powered on the monitor hoping for the best but no change at all. i think they may be more there are alot of questionable spots i see on the board but i'm not the best at spotting them.
So my question is should i resolder any joint i think is suspicion or just leave it alone?Leave a comment:

Re: I-Inc IF281D Display Problem
ok so i plugged in my playstation as a quick test and it work fine for about 2 mins then shutdown. i used a flashlight on the screen and saw nothing.
here is a photo....Leave a comment:

Re: I-Inc IF281D Display Problem
Just to clarify when i took the readings i only had the video board and the power board hooked together then powered it on. Did i need to have the whole monitor assembled it order to get the readings?
As far as the light test i will try it today but i know the power light goes off when i try to plug in an input. must be a self shutdown?
Anyways i'll be back shortly with the results.Leave a comment:

Re: I-Inc IF281D Display Problem
ok here are the results
smaller chip =
2.2Vdc
1.805vdc
3.304vdc
Larger Chip=
2.3vdc
3.304vdc
5.14vdc
I take another photo of the video board so its easier to see....Leave a comment:

Re: I-Inc IF281D Display Problem
Here you go.
Q1 = 30.01 (resistance)
Q2 = 30.10 (resistance)
Q3 = 31.65 (resistance)
Q4 = 28.35 (resistance)
QS1 = 29.99 2 on that heat sink the other read 000.1 (resistance)
F1 = 000.1-000.2 (fuse) (Resistance)
D10 = 0.610 / 0 (diode test mode)
D8 = 0.423 / 0 (diode test mode)
D5 = 0.617 / 0 (diode test mode)
D7 = 37 - 40 but doesn't look like a diode must be mislabled (resistance)Leave a comment:

Re: I-Inc IF281D Display Problem
Test 2 using a screw
Rail 1 = 5.14V
Rail 2
Yellow = 0
Orange = 0
Red = 5.14V
Green = 0
Brown = 0
Black = 21.8VLast edited by AloofOne; 01-14-2012, 04:26 PM.Leave a comment:

Re: I-Inc IF281D Display Problem
i used the black wire from the set as ground. i'll try using a screw. As far as the reading i just copied what i saw from the DMM which has autorange on. do you need me to list which is a resistance test or diode test? i'm not a pro at using this meter. =)Leave a comment:

Re: I-Inc IF281D Display Problem
Okay i'm back with more information.
I took some readings from video board with the power plugged in and connected the power board.
Rail 1 = 5.09
Rail 2 =
Yellow = -21.7
Orange = -21.7
Red = 5.07
Green = -21.7
Brown = -21.7
here is a photo of the area i took readings from...Leave a comment:

Re: I-Inc IF281D Display Problem
Says on the board. model# FSP217-4F02, DC Output +5.0V -1.5A, +5.0V - 4.35A,+24.0V - 5.5A, +12.0V - 4.77A.
i've also taken some readings on the board prior to your post i hope they help.
Q1 = 30.01
Q2 = 30.10
Q3 = 31.65
Q4 = 28.35
QS1 = 29.99 2 on that heat sink the other read 000.1
F1 = 000.1-000.2 (fuse)
D10 = 0.610 / 0
D8 = 0.423 / 0
D5 = 0.617 / 0
D7 = 37 - 40 but doesn't look like a diode must be mislabled
Hope this helps some.

Re: I-Inc IF281D Display Problem
hello again, sorry i haven't replied in some time i was sick last week and haven't been able to do any testing. I was able to borrow a friends DMM of decent quality so i'm hoping my readings with be accurate.
i tested the monitor yesterday by turning it on and just leaving it alone for awhile. It went into standby (orange light) and stayed on for hours as long as i didn't try to input a signal in which case it would turn off shortly after. i noticed that on the video board 1 of the chips (ic controller?) had a solder bridge. Not sure...Leave a comment:

I-Inc IF281D Display Problem
Hi all I'm new here and while searching for internet for possible solutions to my problem i noticed this great forum and thought i would ask for any advice that might help me solve this issue.
I have an I-Inc 28inch monitor that has a display/power problem. One day while i was at the office i tried turning the monitor on and was working fine for about a minute or so until it shut itself down. I turned the monitor back on again and this time it shut down in about 20secs, a third time and it shut down almost immediately. I tried different power cables and different inputs but get...
