i need schematic for this board, busted and burm smd parts,, please help
 

pls. post model # and photo of pcb.

wbr

Got the same one, need help with it to!

Model numbers: rsag7.820.1459/ROH VERF
Hisense HLP-30A11

Input: AC100-240V Max3.5A 50/60Hz
Output: 5VS/0.5A 5VM/1.5A 12V/1A
HV Output: 1280VAC/9.5mA
Pin:150W(MAX);POUT:120W(MAX)

My issues is the backlights are receiving improper voltage and will only light up halfway. If I ground one of the HV lines, that CCFL will light up normally, but if I ground both off the same transformer coil, the backlights will come on briefly then all will turn off. If I short a set of HV lines on the same coil, the whole backlight will work properly til the TV shuts itself off after a couple of seconds. I think I may either have a grounding issue or the "T803" transformer has partially blown.

Not sure how I'd repair the transformer if so, but I'd love to try
