Re: samsung le32r88db with psu 0015aa
so worse case i might need to go into service mode and change panel type
sorry i am new to all this i spend most my time on consoles and phone repairs
if i run into problems would swapping eerpoms from this old board help?
my panel is a V315B1-L01 REV:C3 what would that be in service mode?

Re: samsung le32r88db with psu 0015aa
under the heat sheild is 3 small tantalum capacitors 6.3v and 2 large labled 1000T also a large power coil 220 i could only find the small caps to replace and it didnt help so i just went on ebay to pick up a mainboard
mine is a BN41-00813D and on the tuner it reads BN94-01121N
after searching the best match i could find was a BN41-00813D and the tuner reads BN94-01121S fingers crossed it works by the way the panel is labled V315B1-L01 REV:C3Leave a comment:

omg if i warm up the bga chip for 10 secs with nothing more then my wifes hair dryer it boots 1st time no video errors
reflow the chip with flux five times almost got it hotter then hell on the last go and it didnt change a thing..
yet still 10 secs with a hair dryer and it boots fine still
i think its a case of a new mainboard or just put up with having to wait 5 mins for the chip to warm upLast edited by Warbeast; 06-18-2014, 06:33 PM.Leave a comment:

100% bga chip removed power from wall and left to cool heated the bga chip to normal working temp switch on mains and no error at all
gonna need to reflow the chip i havnt got the tools to reball it so will have to do with a xbox 360 fix lol
by the way when and if its fixed could i hook up a old pc 12v fan mod to help keep it from going again?Leave a comment:

got the panel looking good all options work like movie mode i just picked the next panel under the service menu option think it started with mcb anyway it now showed Bordeaux and looks good
as for the cold start with messed up video i think ur right tom66 it still comes on with screen errors and restarts untill the bga chip gets warm then it will stay on fine with no errors so to test i left it on stby for 30mins felt the heatsink on the mainboard bga chip to check its cool and the error came back when switched on

Re: samsung le32r88db with psu 0015aa
cheers ill give it a reflow if all else fails but it seems like after the eeprom reset the defaults are wrong
backlight becomes less bright when increased
setting video to movie mode makes the picture go grazy
vol does not increase correcly
anyway i can check these default settings?Leave a comment:

ok i feel like a idoit!
the hissing sound really did sound like a bad psu sound however im not silly enuff to put my ear on a psu but i did just unplug the speakers and its stopped
so really my only problem is when cold the display shows lines and a hissing from the speaker that lasts 5mins would this be the psu still?Leave a comment:

ok guys my mother asked me to look at her lcd red light blinks in a reboot cycle all caps on psu look good cy8045 and cm810 with glue looked crap also center pin on qb802 looked a bit brown so replaced these parts
on my meter all 24v to inverter and fine 12v 5.4v etc are all fine to mainboard but still wouldnt turn on then today i had the idea to try and reset the eeprom for 2 secs and it worked came on and seemed fixed
then i unpluged it for a few hrs and when hooking up the mains the psu started to hiss tv turned on with lines on display then after a reboot... -
