Re: hakko tip i dont know
kiriakos mate im just starting out and it was a ebay sale one of those rebranded units a 3-1 hot air, psu, and soldering iron, wep 853d and the ad looking at it says real hakko element from japan but for the inexperinced i never read the ad properly my error i presumbed it was the iron too blue and yellow colour hakko thats there colours im sure and im on a budget arghhh done more digging and seen that the ceramic element come in 64mm and 60 mm im sure thats right so even being a clone iron they sent the wrong size of tip as that tip would have been fine... -
Re: hakko tip i dont know
i done a little more digging regarding this clone iron the hakko data for the ceramic element for the iron state it measures 64mm but mines measures 60mm thats why the tip dont fit snugly so the add they have i think is even wrong as it states genuin hakko ceramic element but that dont measure up to what hakko have and olso the add dont say that the iron is a real one just shows the pic of the iron which gives the illusion its a real one and the term used by them geniun hakko element and olso if u send images to a seller stating the problem can they enlarge...Leave a comment:

Re: hakko tip i dont know
ty mate measured mine at the copper sleave on the iron and mines measures 15mm and yours is 20 mm no wonder the tip moves a few mm as there is 5 mm missing and ill need to contact the seller regarding this fake iron lol just my luck been bursting to use it with the new solder station ty mate againLeave a comment:

Re: hakko tip i dont know
iv uploaded some pics to try show what i mean regarding tip moving the first pic is the model the next 2 pics show diffrent lenght as i pushed it in for 1 pic and pulled it out for the other and finally the last pic shows how much of a gap there is at the tip but as i said im unsure and some input would be great as im now unsure if this is a real hakko iron as it was stated the real hakko iron so again ty....Leave a comment:

hakko tip i dont know
just got my self a solder station as i had 3 fire starters the plug in mains type,,but anyway my issue is it came with a hakko 907f esd safe soldering iron but is the tip suppose to move up n down a few mm when locked in place on the iron ,as i thought it had to be a tighter fit than that no movment but im really unsure ty . -
Re: can the psu be removed for testing

Re: can the psu be removed for testing
im not getting off to a good start i have 3 solder irons and all wall mains type diffrent wattage thou from a weller 15 watt mains power and 30 watt skytronic mains iron and a other 15 watter.. ill try and get by on what i have iv sent for the replacment ic anyway as i said ill try that and before they arrive ill pratice on some old board with smd ic similar and go from there as iv taken every capacitor out except the largest one on the board and they all looked good their uf microfarad and esr and iv read a few other forums and that fault...Leave a comment:

Re: can the psu be removed for testing
tom do i need anything special in the soldering department for replacing those small ic the controller and the mosfets as iv got nothing to lose by trying to replace those components starting with the controller 3037 and see what that does for me or do u have any idea of how i should proceed without getting a new psu lol and again cheers mate for ure inputLeave a comment:

Re: can the psu be removed for testing
and for the life of me i couldint find the power supply schematic but that item must be somewhere how do the lg techs get by for their info any way the reason i think the fault lies in that area of those 3 smd ic 1 ic controller3037 and 2 ifr7807 mosfets as this is for the 32lc2d lcd tv and the voltages for both broken psu are roughly the same with the origianal showing on its 3.4v =1.00v and the replacment now the same as the original broken lol shows on its 3.4v line=1.39v. did the numbers look ok when i tested those mosfets i mean did i...Leave a comment:

Re: can the psu be removed for testing
tom mate im learning as i go so the iru3037 is the controller how would i test check this smd ic as i rekon this area hold the key to the low 3.4v issue i think lolLeave a comment:

Re: can the psu be removed for testing
i dont know if iv tested these components correctly as im reading on q204 source to gate=.181
source to drain=.308
q205 source to gate=1.655 and rises
source to drain=.308 and rises both are irf 3037 smd ic using my dmm on the diode setting have i done this correctly to test those mosfets ty again guysLeave a comment:

Re: can the psu be removed for testing
just my luck ehh i dont have bench power supply as im at the end of my tether with this psu as im not prepaired to purchase another one so my aim is to try and repaire and learn more if possible and fix this and i belive iv narrowed it down to those small smd on the solder side of the board and it is this, i would like to check their voltages those components as i think the low 3.4 v is down to those being bad thank you very much for replying.Leave a comment:

can the psu be removed for testing
i was wondering if its possible to remove the psu from my lcd tv and have it on the table so that i can get a better idea of the volts around those small smd at the solder side of the board on the 32lc2d lg, and if so how i have a idea how it may be done but not a 100 percent -
Re: need help schematic psu 32lc2d lg
more problems with this tv i was too quick to think a replaced av board fixed the problem as i posted that it was sorted my mistake ,i ended up replacing psu which in fact fixed the issue of low 3.4 v line,and brought it back to good health but now its back same issue as before low 3.4 v line and c208 showing as popped capapcitor,so im thinking those small ic on the solder side of pcb are faulty think 3 in total irf etc as iv replaced all caps with good brand panasonic etc and they show good on my wee cap esr tester. and i still didint find...Leave a comment:

need help schematic psu 32lc2d lg
been looking for a lg 32lc2d schematic for psu, as it seems to be very hard to obtain iv tried looking and can find the manuels for the set but the psu dont seem to be there on it.
is there any other models of lcd tv brands that psu was used on thankou -

toshiba equiem p300 16 t
my issue is obtaining a small flat ribbon cable for the said laptop the toshiba equiem p300 16 t model.as this goes from the on/off switch to motherboard but mines is defo need of replacment as ull see in pic.
i think iv measured the item correct in it being 73mmx5mm 4 pin with a 1mm pitch the gaps between the conductors think thats right.
but will i be able to use a cable from other laptop etc diffrent brand but same cable in use as the price if seen new is a bit strong i think for what it is.
thankyou any input will be great. -
toshiba equiem p300 laptop screen flicker
my issue is that when i open the lid of the laptop the screen turns pink diffrent colors the thing is if u catch it at the right angle u get the normal screen . has any body noticed that on these laptops as after some digging iv seen that the metal brackets on the lcd screen that are screwed to the laptop base the one on the left has snapped. which i thibnk has maybee loosened the solder joints of the connector for the inverter cable connection to laptop mb hope iv made sense explaining this thankyou . -
testing the solder side of board
could some one tell me the proper way to test for volts on the solder side of the board,as i flipped my power board over and connected the ac wall cable to it but nothing so the thing is do all the p connectors need to be added p101, p102,p103 etc i even connected a short cable from the ground screw hole area on the psu to the chassis on the tv sorry if this sounds a silly question but im trying to learn as much as i can obout my set for future troubles always good to learn to stuff thanks again.
