Needless to say, I just lost some money. Couldn't see any screen damage at all. Set was completely dead. Got it home, gave the LEDs a test, and it had a crack right up the middle.

Re: Who's got tricks for detecting a cracked LCD in a dead set.
I always ask them to turn it on. If it wont, I take my cell phone with the flashlight app and shine it at an angle to look for cracks. It dosent always work though. Thats why I love plasmas, cracks show up clear as a bell. -
Re: Who's got tricks for detecting a cracked LCD in a dead set.
I like that about plasmas, but nobody wants to buy them after I fix them. Flashlight didn't work on this one. Maybe I need one of those million candle power ones.------------signature starts here------------

I think they're better, but people always say "Oh no, plasmas are dead, I don't want one of those."------------signature starts here------------

Re: Who's got tricks for detecting a cracked LCD in a dead set.
In OZ plasma been out for some years and now getting too old. I have a Panny and an LG waiting for fix but parts either hard to get or ridiculous pricing e.g $250 for a main board !! They'll be scrapped shortly if I can't get them going. Those that have them do like them and panels do seem to last OK despite half life warnings. Also here our electricity prices very high and people these days conscious of power usage. As for screens yes turn on or don't pay very much - I picked up a binned set recently hoping screen OK as I had same set new but with broken screen, got home turned it on and everything worked perfectly !! Ya can't win ! Or should that be lose ?Comment

Re: Who's got tricks for detecting a cracked LCD in a dead set.
I'm about to drive 100 miles tomorrow to get a 50" LG smart. Only because I know it's just bad LEDs and I have a complete backlight assembly for it and a buyer already waiting for me to find him something. Guy sent me a video, so I know what I'm getting. But I think I'm not risking much on dead sets anymore.------------signature starts here------------

Not.much different.here in the states.
Nobody wants a plasma anymore it seems. I have 5 Panasonic plasmas all with bad SC boards. It takes time to troubleshoot and repair these just to sell for 100 to 150 max. It a a joke. Thinking of scrapping these myself as there taking up room and my wife's bitching about them.
Sad day.Did I leave the soldering iron on?Comment

Re: Who's got tricks for detecting a cracked LCD in a dead set.
I've no problem selling plasmas, I just call them flat screen TVs. If people ask I tell them they are plasma. But most don't care.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Who's got tricks for detecting a cracked LCD in a dead set.
Here in the "Sunshine State" I try to take the TV out side in the bright sun to look for cracks but even then I still get a cracked screen. Trying to check for cracks in a TV that would not turn on.Comment

Re: Who's got tricks for detecting a cracked LCD in a dead set.
I've only got one before.
It's pretty easy to spot.
Looking at an angle, you can usually see the LC damage. Pressing the screen lightly around the suspect area will show the LC moving around. (LC = Liquid crystal)
Anyway, I don't tend to do many TVs any more.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Who's got tricks for detecting a cracked LCD in a dead set.
My rules when looking at a broken TV:
If any parts are missing out of the TV it's a $35.00 charge to haul it off.
If I can't inspect/test it before taking ownership, or the screen is cracked I will haul it off at no charge. This includes dead units that won't power on or otherwise cannot be checked.
I only repair TV's that are in near perfect condition. Scratches and condition issues make it a parts TV automatically. After all why buy a used TV if it looks like hammered dog squeeze?
If it powers up and there are any problems with the display, or won't make any kind of a picture it's a $10.00 unit, period end of story. The power cord, working remote and owner's manual are worth an additional $2.00 each. A pedestal base, depending on condition is worth from $3.00 to $12.00.
I do not pay over $35.00 for any broken TV, regardless of condition or problems.
This strategy has netted me 4 broken LCD TV's this week for $10.00, two with display problems and two with bad screens, including a Toshiba 70"! Add another $20.00 in gas and that's what I have in them. I'm going to look at another one tomorrow for $10.00 with sound and no picture, a Samsung pn50a510p3f.
The way I see it, buying broken plasmas comes with risk no matter how good they appear, and I can't do this for entertainment value. If I'm not guaranteed a profit before I leave the shop it isn't worth it.They call me......."threadkiller"Comment

Re: Who's got tricks for detecting a cracked LCD in a dead set.
If that's all that it needs, indeed a good score!
I picked up a Samsung UN60J6200AFZXA with a busted screen for free. I hope I can find a unit with bad LED's or something and use it for parts.They call me......."threadkiller"Comment

I used to buy ones with broken screens, but now I've learned that when you say you don't buy broken ones, people just start giving them to you.------------signature starts here------------

Re: Who's got tricks for detecting a cracked LCD in a dead set.
Speaking of that, just got a 32" Roku TV with a busted screen given to me...not bad. Paid $15 for a nice looking PN50A510P3f with sound and no display or backlights, new remote, power cord and owners manual in the original bag!They call me......."threadkiller"Comment

Re: Who's got tricks for detecting a cracked LCD in a dead set.
If someone texts me offering one, I just say I don't buy broken ones.
Otherwise, people will realise their broken ones aren't worth anything, and will make them appear good.
That's my theory, at least.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

by double_DDHi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
by disorderhello guys,
i need help to repair a edm-033 ps2
history : as always hdmi port and usb ports destroyed after unplugged
after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
so i changed it
now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...
i don't see any projection of liquid metal on pcb.

by BetonHi guys!
I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
I have a bench PSU and if I try to inject voltage the voltage... -
Hello everyone hope all doing well!
I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...3 Photos -
Hello, today I'm working on this lovely MSI Raider GE75 gaming laptop which I bought to flip. Unfortunately, I believe the CPU is toast but I wanted a second opinion before I chucked it into my spare parts bin. I will not have most tools with me today as I'm away from my workbench but I have the basics (a good multimeter, a horrible iron, a solid screwdriver, and my trusty thermal cam). I do not have the original 230w charger, but I have a Dell 180w which was sold with the device and reportedly "worked fine for them".
