techwood 32". replaced psu and now standby light is flashing intermitantley

   Hi conman78
  Don't use quick blow fuses in any case as they cannot withstand the inrush surge. Use anti-surge types as denoted by A/S***mA or A as the case may be.

hi paul. thanks for that mate , i wasn't sure which one's they used so i thought i'd go with quick blow to be on the safe side. i've bought a board from flea bay and put it in, i'm not sure if i've been ripped off tho .the fuse doesn't blow anymore but the power light that surrounds the power button on the television is just flashing on and off blue intermitantley and randomley,is this a power supply fault or could it be a fault with the main board ? there is no life when i press the button but when i switch the power off at the wall then the button light stays on constantley for a few seconds and then dies out ? . can anyone help me on this please ?

Hello
There are slight differences with these PCB's.
If they have the same panel number, and sockets,
check the values of resistor R965 (near sockets),
and on the print side, R966.
R965 could be 3K3, or 680R, and R966 1K, or 150R.
Hope this might help.
John

hi watteau . thanks for the help m8 its much appreciated. i've checked the said resistor's etc and they are all exactly the same ? :dubbio: i'm pickled now because i've got one psu that blows the fuse apart and one psu that makes the stand bye light flash randomly ? has anyone had a similar fault where the blue standbye light that surrounds the power button flashes ?

conman78:
hi , i've changed the 15uf caps c877 and c878 , still pulsing ? so i pulled the plug pl803 of the board and instead of the standbye light pulsing - the back light of the screen pulses ? if i put pl803 back in and pull out - g800 then i get pulsing standbye light again ?  :wallbash:
