IPLV-42 Rev 1.4. resistor values needed
« on: May 09, 2012,16:55:12 »
hi, im taking on a repair of IPLV-42 Rev 1.4. psu from atec av370w lcd tv, problem is failed caps C103, C104, etc,33uf and 0.68uf type, diode 601 is short in fact split, also resistor 108 and 104 burnt, can anyone tell me the values of these resistors as i cannot find schematic online, your help will be appreciated, regards andre

diode 601 has been talked about as use either a 12v or 13v zenner the resistors i do not know
check also Q101

hi, have replaced diode 601 with 13 volt zenner, also Q101 which was short, + all surrounding caps, just these dam resistor values needed to complete repair, if anyone out there has this psu, and could check these values it would be very much appreciated! regards andre

from my (non-working yet) PSU, the values are 2ohm for R108 and 47ohm for R104. You can also verify these from the high-res scan of the board here: http://flattvparts.co.uk/bmz_cache/d/da5e2ccbcd24a31d6071835132922a1c.image.2000x1306.jpg

hi, thanks for that, still got tv and not been worked on since my last post some time back, did change resistors
 R108 and  R104 with 2 ohm for 108 but r104 was guessed at 10ohm or something similar, set fired up with very dull pic, Q101 got very hot then 12v zener diode went short, will  re fit resistors and and other components and see if this gets the set going, ps, psu is horrid to desolder   with solder on both sides on board, nasty!  :41: Q

On the internet I get the following information:
Q-101=2SA1275
R-108=2R/0,25W
R-104=47R/0,25W
D-102=1N4148
D-105=UF4004
D-601=18V/400mW
C-103=0,68uF/50V
C-202=1000uF/10V
