Alguém aqui que saiba onde encontrar um diagrama de circuito de uma placa de circuito CV9203L-R??

Brand: STANLINE 22'' LED 12V screen+DVD player
Partnumber mainboard: CV9203L-R
Type: TDL22R4ST006
Problem: Tela preta, som da fonte ---> SEM luz de fundo!!!

á em algum lugar um curto no U17 ou capacitores em torno deste chip AHI6EB. Também medindo a tensão errada no conector vermelho (inversor). Deve ser 12V/Bl On/Off/GND



Tentei encontrar um diagrama de circuito CV9203L-R na internet, mas sem sucesso. Talvez um de vocês possa me ajudar a descobrir qual é o partnumber desse AHI6EB? (ou é AHL6EB?)

Muito obrigado desde já pela sua ajuda.

Anybody here who knows where to find a circuit diagram of a CV9203L-R circuitboard??

Trying to figure out what kind of chip U17.

Brand: STANLINE 22'' LED 12V screen+DVD player
Partnumber mainboard: CV9203L-R
Type: TDL22R4ST006
Problem: Black screen, sound from source ---> NO backlight!!!

There is somewhere a short in U17 or capacitors around this chip AHI6EB . Also measuring wrong voltage on the red connector(inverter). Should be 12V/Bl On/Off/ GND



Tried to find a CV9203L-R circuit diagram on the internet but no success. Maybe one of you can help me with a figure out what the partnumber is of that AHI6EB? (or is it AHL6EB?)

Many thanks in advance for your help.

Thank You for your reply Xeontec! 

Unfortunately I can't find any datasheet of this chip AHI6EB?? Do you know a similar component what does the same of another CV9203 model?
