Title: AG Neovo X-17A
Post by: sabre504 on May 28, 2012,07:51:59

HI all
have an AG Neovo X-17A with power problem .

12v 3.5a external psu working no power to screen
Have found the problem on the main board Q801 chip burned out and the only readable numbers on are RSS050 on top line and on second line just the last digit is 3

Have found a pdf relating as close as i can but not sure if its correct just wondered if anyone had done these before or had a board showing correct numbers that they could quote to me .

Think the chip blew from a surge as i cannot find a fuse on the board
sheet and pic attached
Thanks in advance
Paul

HI all update on this iit is now working

Replaced U801 and was rewarded with power light and no signal reading on the screen .

This unit has s-video and composite as well which are both working and vga and dvi inputs working .

Also had to replace a fuse and cap on the inverter .

Parts replaced
Q801 used a TPC8104
U801 used a AIC 1578
2 x SS14 Diodes
ZD801 used a 6.3v zener diode

And while opened up i changed 1 16v 470uf and 3 x 1000uf 10v on the power input side.
I have had it running now for about 12 hours using a dvd player via the s-vid connection with no problems
