Identification Problem?
Hi, can anyone give any assistance with this item - having problems finding out what it is as one is burnt out on board.
looks like id WG9J or W89J ?
Picture not the best but should be ok for id process.
this is from an unbranded 32" lcd tv but matches Technika type and it off the main board L2M08 2008.12.26.
any assistance would be great.... -

Hi, can anyone point me on the road to finding this fault, as stated I am a newbee and understanding the route of the electronics is apparently hard for me if I am not getting the value at the output to the main board how do I check track to find where it stops. Thanks again for any assistanceLeave a comment:

Re: Help meeeee. Advice needed
Back again - right testing some bit before and well I am stumped but you clever people may know some tricks (I hope
) - right tested some bits on the psu to check vaults - big filter cap c819 tested and 325v going across - two red caps tested and good vaults also, stby boot area caps tested and of the three 3v to 0v only showing ???? ic806 chip that feeds the stby boot area (i think) pin 2 8 - 11v up and down, pin 3 0v, pin 4 0 - 1v, pin5 323v, pin 6 & 7 22 - 40v up and down and 8 22 - 54v up and down again......?...

Re: Help meeeee. Advice needed
Right bought this power supply from ebay (working from set with damaged screen) but when i put it in it had now power?? (stupid arse see in a min) so moved parts from this board and replaced caps/resistors and other parts until I obtained power with blinking light saga / then it dawned on me that the board i bought was for my tv but had a extra power plug that needed jumping hence put all the parts back and still get the same problem blinking led - I am going to test the main filter cap for vaults reading and check the standby caps for vaults also...Leave a comment:

Re: Help meeeee. Advice needed
hi, the main board is disconnected - do get a steady 5v on 5vstby then it moves - not sure if it is the way I am taking the reading with the multimeter but I have checked the jumper connections feeding this section and the results are the same two at 3.3v and two that fluctuate from 2 - 5v? do you think there could still be a fault on the psu? also do you not have to connected the stby together with a resistor to enable a power boot to check all vaults on the psu? or is that only when you have a steady 5v on the supply? thanks again!Leave a comment:

Re: Help meeeee. Advice needed
Thanks for the help so far, I have put the replacement board in and power on - led solid for 10 secs and the flashes in steady flash. checked the pins going from psu to main board and found that at 5vstby I get a reading fluctuating from 0.4 - 5.1v and 3.3vstby gives 3.3 - 3.4v and 3.3sti gives 3.3v the +5v gives 2.2 to 6.5v. the psu is giving a hmmm noise on and off constant - looked at the main board and no obvious signs of faults and tested all fuses s/mounted and they seen good???Leave a comment:

Re: Help meeeee. Advice needed
Hi again, just replaced the psu with another bought from ebay (working) but still have a solid light for about 5 - 10 secs and then it flashes -I think psu is working fine now but how to check - can i make the psu fully boot to check vaults at the pins ? to confirm the power board is ok? and also what fuses are on the main board - power only went off when my son put the scart lead in - thinking he shorted it then on the main board -- the resistors that blew where at location r829 r830 burnt / black mark/hole on them and they where on the power board...Leave a comment:

Re: Help meeeee. Advice needed
Thanks for the reply - would this cause any faults that I am seeing - just checked the vaults from psu to main board only getting 3.3 on two pins and one which is fluctuating - do i have to do the resistor to stby to enable bootup to then see if vaults are recorded at the pin outs - thanks in advanceLeave a comment:

Help meeeee. Advice needed
Hi, I have a great tv from alba with the lovely power board by vessel,tv went dead when son plugged a scart lead in nothing at all. Replaced some resistors and a few caps just on case and also q813 q814 checked diodes and they are ok but now all the tv does is light(led) comes on and the n after ten seconds it flashes in no pattern. Had a quick check for vault readings at the rail to the main board most pins read 0 and I have one at 6.6.. what route to go down if any help can be given or should I just buy a newsgroup vessel.. also if you look at one of the cables going to the main board it has... -
Re: Please help power supply problem
if you look at the mainboard you see a few wires attached and there seems to be a piece metal (half circle) should this be whole (full circle) and what is it for...Leave a comment:

Re: flashing led
just for info not sure why on the main board it has cables with a magnet/circle metal piece tied but on other pics it has been noticed that it should be a whole circle and mine is just a half circle - is this ok or has it broke off ???Leave a comment:
