Hisense 32A4G Vidaa

[Fengo]

Good day gentleman

I hope someone can assist.
I have a Hisense Vidaa tv that only shows dark screen, no picture. It started with vertical lines moving in from the left and would fade away after 5 minutes.

Currently only show black screen, with sound. Backlights fully working.

Any help would be highly appreciated.

Thank you

Most likely a bad panel , Check voltages see if you get 12 volts to the tcon or the panel Board, Next check on panel board vgl , vgh voltages see if they come on briefly when you power on the tv , if they do and then go away , its the panel thats faulty most likeyl

Hi Sigmeyer

I get 12v on mainboard flex without screen board attached.
With screen board attached 12v value change to -1,8v as soon as switched on.

Other voltages on screen board is:
VAA 11,8v
VSS -07,94v
VCOM 6,25v
VDD 3,29v
HVAAF 5,72v

WP 0v
SDA 3,29v
SCL 3,29v

Thank you

Couple things to check, check the little mlc caps on panel driver board for shorts or very low ohms, check the resistors, look up the datasheets for those two IC's, see what kind of voltage you're getting on those.

Re: Hisense 32A4G Vidaa

Think about it, YOU have the components in front of you, look at them, see small writing on top? put that info into a search, so just put in the search, example: FQPF11N50CF datasheet. DO NOT put that in it is just an example of a random transistor. We can't test these things for you if we don't have the board, understand? A lot of this stuff isn't easy, so you won't solve anything by just putting "good day plz solustion" if you don't want to do the work give the tv away or recycle it.
