Re: Hannspree T280H not turning on
I checked the joints and they looked good.
Will check the resistors and diodes later today, working right now.....

Re: Hannspree T280H not turning on
I was able to jumper #1 & #7, I couldn't find a 1kohm resistor.
No backlight, also no 12v or 5v.Leave a comment:

Re: Hannspree T280H not turning on
So, everything is reconnected, I tried to heat the board with hair dryer, and measured leads with meter.
12v = 0
5v = 0
5vsb = 5.2
The large brown cap, 450v 120uF reads 169v and does not change when power button is pressed.Leave a comment:

I just checked the screen with a flashlight, it all looks the same, no cracks or bubbles. The cables all look to be intact.Leave a comment:

Hannspree T280H not turning on
1st Post here guys. I have a T280H that the cat knocked over. Everything else was fine before the fall, but now there is no display. There is a yellow LED that pulsates dim to bright.
I have taken out the power supply, R0800-0805-060.
I tried to test the pin outs 12v, see pic, which reads 0.00
I do have 5v.
Also, I noticed, the 2 metal heat sinks, checking the voltage between the 2 of them reads ~60v, but I am not sure if that is normal.
I have looked at another post, similar PS, but a little different.
Thanks in advance... -
