hi does anyone know if the leakseaker meter is any good

Re: leakseaker
Leakseeker testers work well for locating shorted components on a pc board when one does not have a strong suspicion of any one component or group of components being shorted. In that case, unsoldering large numbers of parts would be impractical. The Leakseeker can point to the offender rather quickly. This type of tester is more useful for locating bad semiconductor components such as ICs, transistors, diodes, etc... that happen to fail in a shorted mode. capacitors can and do also fail that way, but not very often [ in my experience].

Re: leakseaker
hi thanks for the reply do you know an a good place to buy one also would they be suitable on a smd componentComment

Re: leakseaker
Interesting device. Yes, it should work on any component that is loading down a power, signal, or data line. It doesn't matter if it was SMD, through-hole, or even point-to-point wired. I can think of hundreds of times this would have saved a lot of time and trouble.Originally posted by insomnia
One thing I saw the was a little alarming (if it wasn't a typo) was that it uses an 8 volt source. If that isn't a typo, it could do serious damage to most ICs on the line.
PlainBillFor a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.Comment

Re: leakseaker
A better voltage would have been 3.3V much more IC friendly.Elements of the past and the future combining to make something not quite as good as either.Comment

ye my brother had me to look at some mobo,s for him and it is very puzzling
with the smd components i put in 8 hours one evening messing with this board to find noting to much to go true so i thought it might be handy how about using this is it hard to use

Re: leakseaker
PlainBill, I purchased one yeserday after asking the manufacturer about your concerns (which concerned me too). Here is his response to the question of 8 volts cooking chips:
"NO, as the manual describes, it is current limited. The 8 volts drops down to 5 to 10 millivolts even on high shorts, and down to microvolts on near-zero shorts. In 20+ years that LeakSeeker has been available, there have been zero reports of any problems caused."

Re: leakseaker
anyone have experiance with this tester?,is it any good?fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!
----------------------------------------------
please let us know if everything works ok if your tv gets fixed, as it will be and aid for anyone else having the same problem and wishing to fix it.it would save people clogging up this site with topics that are duplicated,and can be found easily using the search function.,and taking up valuable space.enjoy your fixed tv!,hopefully!Comment

Re: leakseaker
I bought one about a week ago. The build quality is very good. It seems to work fine, but i pretty much only have multilayer laptop boards to practice on. apparently it still works on multi layer boards, but the process is more complex. I'm stil llearning to use it, and hope to have some actually useful input soon!Comment

Re: leakseaker
Where can you buy it?
Are there different shops?
I find only one.Comment

Hello:
I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.
I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :
D608, good
D618 RF101L4S, good (See warning 1 below)
D619 RF101L4S, good (See warning 1 below)
D865 RF101L4S, shorted (See warning 1 below)
IC464 Inverter HA MC74HC1G14, shorted...03-09-2020, 12:00 AM -
Hi to all,
the owner of this machine gave it to me after having opened it to take off the dust from the inside, telling me that after that it didn't start anymore.
I found that one of the DrMOS (AOZ5016QI) on the CPUCORE was shorted between VIN and VSWH, and that one of the two n-mos connected to the power jack was shorted aswell.
I unsoldered the two shorted components and verified that there were no other short circuits, then decided to power the mainboard, firstly with the lab power supply, then with its original HP 200w charger, but the behaviour is the same, the board starts... -
Hi,
today I got Razer Blade 14, Ryzen 9 6900HX and RTX 3070Ti.
Laptop was completely dead. I found shorted CPU VRM mosfet, shorted 19V mosfet and blown battery fuse.
I replaced it all, but still on CPU coil where mosfet was shorted I got very low resistance, near 0 ohms. On other CPU coils I got around 3 ohms.
Laptop now raises voltage on whole board, but still nothing comes on the screen. CPU gets 0.7V on all coils except the shorted one. CPU gets only slightly hot, below 40 C.
I removed coil and injected 0.7V, it draw around...09-27-2024, 12:44 PM -
Hello,
This is my problem:
Laptop: Dell Latitude 5501
Motherboard: EDC51 LA-H181P
I have two power rails shorted to ground, +1.0V_PRIM and +3.3V_ALW_PCH. I removed solder on PJP302, +1.05VALWP (pad1) not shorted but +1.0V_PRIM (pad2) shorted.
I also cleaned PJP38, pad1 not shorted, pad2 (+3.3V_ALW_PCH) shorted to ground.
I measure the resistance of all the coils on the motherboard and they all were not shorted to ground except coil PL301 before I removed the solder on PJP302.
I injected +1.05V - 2A...
