Re: Wacom cintiq dtz-2100 power issue (need ideas)
Can you explain how vcc works on this chip because that is also going into the weeds. Is it strange for ic5 to be sitting at 4v I'm wondering if it's shutting off due to over voltage....

I got it to turn on again long enough to take good measurements. These are correct with correct pin labeling this time
IC5 1-8 working: 12.49, 5.23, 7.00, 4.30, [COLOR="Red"]4.07[/COLOR], 0.474, 0.797, 0.00
IC5 1-8 broken: 12.49, 0.62, 12.10, ~~~, 0.0, 0.0, 0.0, 0.0
IC6 1-8 working: 12.49, 5.23, 6.9, 4.32, [COLOR="Lime"]3.297[/COLOR], 0.540, 0.802, 0.00

Yup, I brainfarted on 5-8 they are reveresed. That 4volts is 4v before and after the coil I have a fluke 87 which is fairly decent.
What I mean by decaying is the voltage starts around 2-3v and goes down as something in the circuit drains.
The 12.49, 6.29, 12.1, decaying order is 1-4....Leave a comment:

Re: Wacom cintiq dtz-2100 power issue (need ideas)
When the unit is not funcioning both ic 5 and 6 have the same outputs 1-8:
12.49, 6.29, 12.10, decaying voltage, 0, 0, 0, 0.
I only managed to get pins 5-8 on ic6 while it was working 0, .8, .55, 4....Leave a comment:

Dumb question, but where would I source these parts I can only find the 7085 on ebay and it looks like a 2-3 turnaround on shipping.Leave a comment:

Re: Wacom cintiq dtz-2100 power issue (need ideas)
IC7 - M35L 1117-18
IC6 - APW7085 AN66L
IC5 - APW7085 AN66L
IC4 - APM3020P ON53R
The two caps are LF 270C
The board isnt working long enough for me to track down the 3.3 source. It looks like the IC5 and 6 chips are meant to generate this. Do you think I should just swap those out and see what happens?...Leave a comment:

I'll try to check on that when I get home. The discoloration is not as evident in real life, I think it may be just some flux residue that is getting picked up by my camera. Ill try to take a few better photos as well....Leave a comment:

It appears the board looses all 3.3V when it is not functioning.Leave a comment:

Re: Wacom cintiq dtz-2100 power issue (need ideas)
IC7 Has readouts of GND, 1.8V out, and 3.3Vinput when the unit is working and 0V all around when it isnt. The other voltage regulator is 6.2 adj, 12V input, and 12V output when the unit is working and when it is not.
The inductors on the left is measuring 4 volts and the one of the right is at 3.3.Leave a comment:

Wacom cintiq dtz-2100 power issue (need ideas)
Good evening. I figure you can find anything on the internet, but I've been stumped.
I have a Wacom cintiq 2100k I acquired that randomly powers off. When you let it sit for a while unplugged it powers up generally on the first try and will stay on for a few minutes. It then goes completely dead (no lights). If I wait, it normally comes back on after a minute or so and then repeats. Generally it powers off faster and stays off longer if I leave it plugged in.
I've done some debug by unplugging boards one at a time and I believe I have narrowed it down to the middle... -
Re: Wacom Cintiq 21UX Garbage Everything
I am also having power issue with mine. It powers off randomly and then will come back on for a period of time. I seem to be getting a good 12 volts to the main board when off, but that drops to 11 and change when its on.
Were you able to resolve this?...Leave a comment:

Also does anyone know what the board at the top center of the TV does? I can't get the cover off it currently.Leave a comment:

Re: 52LG50 Has Mind of its own
Well I have the same problem and I've read that most people have replaced different boards and it reall has only fixed the issue for a few weeks.
I have figured out that if I disconnect any one of the 4 connections to the LCD the power stays on or off. So my thought is that something is not able to draw enough power to run all four. Maybe an electrolytic cap is starting to fail and needs to warm up before functioning. I don't have any obvious ones but if they are crapy caps they might be performing just below spec.Leave a comment:
