Re: Samsung PS42Q96HD Clicking
ok fair enough,
looking at the power board it looks like someone has already replaced the common parts,
guy that gave it to me said that he had it looked at and "they fitted a kit" but it was still clicking, so i guess what they fitted was the common ics and caps.
am trying to get hold of a dump of the 24c256 for this model to test it again, as when i installed the chip from the dead board it powered up fine

Samsung PS42Q96HD Clicking
hi guys,
i have a samsung PS-42Q96HD that keeps clicking, heres what i have done so far,
checked the power board, caps ect all good and have already been replaced, so i did the control board test and the set powers up and displays the test patterns perfectly, from this i assumed it was the av board that was switching the set on and off,
i ordered a 2nd had board from the well known auction site, pugged it in a the set powered up and ran perfectly for hours, powered on and off a handfull of times to be sure, all was fine so i switched the set off and... -

Re: LG W2234S-BN Faulty Colors
ok problem solved guys, was the lead!!!!! works on every other monitor i have here including tv's, but when i tripple checked the lead its self it appears that the gnd pins (5-10) are not connected!!!!!!!!!!!!!!! so i grounded the pins on the main board and vola pic perfect,
on the main board pins 4 and 6 are connected to gnd but 5,7,8,910 are not!! i guess all my other monitors must self gnd the pins together!!
thanks for all the help guysLeave a comment:

Re: LG W2234S-BN Faulty Colors
caps look ok, but dont have an esr meter here atm so i will look see if i have spares and replace them and see, dont think its the backlight tho as the logo is perfect and brightness seems to be consistent,Leave a comment:

Re: LG W2234S-BN Faulty Colors
No dvi on this one have double checked all the suggestions so far and still the same, don't recall seeing a reset in the menu will have another look tomorrow, did use service menu to auto color and init the nvram,
I'm guessing that the bit that displays the logo on boot is the same as displays the graphic from the pc, thus eliminating it being a problem with the circuit between the panel and main board?
Is there anything that would make it display all color as red? Sort of combine the signals into one??Leave a comment:

Re: LG W2234S-BN Faulty Colors
had the same thought earlier when i was checking the pins so i re-soldered all 15 pins while i was there

Re: LG W2234S-BN Faulty Colors
Hi,
i have tried the ribbon cable, but i will triple check it again, was first thing i checked before i flashed the spi chip, but i will recheck all the connections are solid, dont think thats the problem tho as the main logo displays fine, perfect color and everything, even the menu displays ok,

Re: LG W2234S-BN Faulty Colors
Hi thanks for the reply,
that's what the picture reminds me of too, when a pin snaps in the connector but have already checked the cable as it works fine on another monitor. have also checked pins in the monitor female connector to check they are not broken either, i have continuity from end to end no problem, i will triple check just to be sure tho

LG W2234S-BN Faulty Colors
Hi guys,
i have a LG W2234S-BN that had the corrupt flash and would not power on, have reflashed the chip and the monitor now powers up fine and works,
problem is that when i connect the vga the display is red as if the blue/green are all removed, but its not the panel as when the logo comes on its fine,
im guessing the fault is on the input between the dsub and the tsumu chip.
i have checked the parts on the input side but cannot find anything wrong?
have attached pics
any ideas?... -
