Re: HANNS G HZ281 White Screen
I started testing the items you listed and got thinking that I already tried a new TCON board so I didn't suspect that I had a shorted component there. I tried unplugging one of the cables going to the LCD (CN500) and the voltages are now as follows...
VCC = 3.53
VDDA = 13.44
VGH = 22.89
VGL -8.1
I also see that with one cable unplugged, half of the display appears to be working to some degree (See attached photos).
Also, VGL starts at -8.1v and slowly goes to -7.4v and then switches to +1.638v...Last edited by thajenius; 05-31-2015, 11:48 AM.Leave a comment:

Re: HANNS G HZ281 White Screen
Sorry Selldoor, I thought I read somewhere that they wanted images offsite. I don't see an option to edit the post now to fix.
Thanks for your response Momaka, Here are the voltages you asked for...
VCC = 3.288
VDDA = 4.80
VGH = .647
VGL = .952Leave a comment:

HANNS G HZ281 White Screen
Hey Guys, I've got a HANNS G that turns on to white screen. I have replaced the larger caps on the Power Board and power going to main board is steady 5.14v on two 5v leads and 5v SB. I power at the regulator of TCON board is 5.14v and 3.1v. All fuses I found appear to be ok. I have tried another TCON board with the same result. Where should I look next?

Hello all, I have come here to seek answers for a dead monitor and maybe even some other dead electronics lying around. I have a general understanding of electronics but need some help in the more advanced stuff.Leave a comment:
