Re: 245BW, can't find problem. No 24 or 6.3V, standby is good.
Well I don't know what it is but I replaced it with the exact same type.
One here for $4

I understand how you feel. There are very few options at this point. I have been unable to locate a schematic for this power supply.
With an oscilloscope and isolation transformer we could determine if the IC is 'live' or not.
The symptoms do not match a shorted output diode, but that could be tested. It is the large diode mounted at a diagonal to the right of the standby transformer.
Replacement power supplies are available for under $55.

Well it's too late to call today so I guess I will send a e-mail and try calling tomorrow.
EDIT: Well now I have to fix this monitor ASAP. I got my Dad a new video card and it won't work with his CRT for some odd reason.Last edited by epicelite; 08-12-2011, 05:33 PM.Comment

Re: 245BW, can't find problem. No 24 or 6.3V, standby is good.
Hold it. Something is seriously wrong here. I've been dealing with the same power supply on this thread. The title of this thread indicates you have standby power. In post 1 you said the power light was on, that would indicate the standby supply was working....
Awww, crap!!! I'm sorry, I confused the S_B output with the 5.4 main output. Well, we're going to be following an existing trail.
First question: Does the power LED respond when you hit the power button - turn on and off?
If it does, the second question is: Does the voltage across the 82uF, 450 volt cap jump up to over 350 volts when the power LED is on?

Re: 245BW, can't find problem. No 24 or 6.3V, standby is good.
ON: 422V
OFF: 168V
Volt meter on the 1000V setting.
SO YOU'RE SAYING I SPEND $9 FOR THAT NEW IC AND SHIPPING AND IT WAS FOR NOTHING!? >:|

Re: 245BW, can't find problem. No 24 or 6.3V, standby is good.
Yes.
The next step is to measure the voltages on the main SMPS controller - ICM801. Set your DMM to the 20VDC range, use pin 4 as the ground point, and measure the voltages on every pin of the MC33067P. Report the readings.

Re: 245BW, can't find problem. No 24 or 6.3V, standby is good.
Package designation here. Note the notch at one end, some manufacturers have a dimple by pin 1.
Use pin 4 for the ground point of the DMM. Perform the tests with the monitor plugged in, and the power led on (you may have to hook the monitor up to a signal so the monitor doesn't go into standby.

Greetings! I have this ERP650-PS atx power supply, it is a relatively simple psu, the primary has a driver IC that controls the two main mosfets (two 20n60S5), together with a Classic Standby circuit with a PWM IC (not a FET like the VIper22A) , relatively similar to the SDC606P.
The whole point is that I got this power supply years ago when I had no knowledge, apparently the PWM IC was burned because someone turned the power supply on with the switch at 110v in a 220v network (classic error). Important detail: the power supply at the time came without the primary capacitors.

Hello everyone,
I'm new to the forum,sorry english is not my first language too, i got a basic plus knowledge, but now i am in this situation where i need some help , i spend good few days reading forums , here and outside , to help my problem solve, with no luck
long story short, i bought macbook pro a1989 820-00850, clean no water damage which was stuck on 5v 0.200/300a i read a lot of forums what that could be , it indicated to faulty corrupted t2 rom
of course before jumping to conclusion and connected to DFU , i believe i done basic checks... -
Hello forum. I've recently been given a Yamaha TSX 120 DAB radio and ipod dock. Its working well however when put on standby its using 6.3 watts. The manual states less than 1 watt on standby. I measured this with a plug in monitor which seems accurate with other items. In use it uses around 7.5 watts. Firstly has anyone who owns a similar radio also got a plug in monitor to check if this is normal with this unit? In the first half a second the monitor shows 0.3 watts which I suspect is what it should use but something is switching it to be almost fully powered. I've searched the manual for eco...03-01-2024, 07:25 AM -
Hi all,
My UN65MU6300FXZC is dead and the standby LED stays off. The power supply is good. The main board is BN94-12434A.
Disconnecting the main board from the power supply makes the backlight come ON.
I did disconnect the panel cables and the WIFI modules, the board is still dead.
I did read in many posts that IC1604 25Q40 becomes corrupted. It has proper 3.3 volt on VCC pin 8. I did read that if I post its dump here someone can fix it. Is that right?
Thanks. -
Hi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.
