Re: Top Half of Dell E151FPb Darker
I've got two. One is in the same category as yours - the firmware is corrupted. Can't find the firmware, I'd have to buy a programmer and rig an adapter, etc., so it's an 'unrepairable at this time'. On the other hand, I have seen firmware chips for other monitors on sale, so if anyone ever does this one, it will be repairable.
The other is a 19" Viewsonic that blows the driver transistors for the inverter (the Royer oscillator design). I've checked most everything I can think of, but don't have the answer - yet. On the other hand, for Christmas I got myself a rather nice variable power supply with current limiting. Real Soon Now I'm opening it up, isolating the power supply for each side, then comparing behavior of each side using a scope. THAT's the one that's been sassing me.

Re: Top Half of Dell E151FPb Darker
ive been reading this forum for ages now,and this is the most excellent post i have seen,not all is what it seems,and never always trust a schematic,i made the same mistake ,i i thought exactley the same thing ,ok i lost a few quid but the time spent ,i learned a hell of a lot,the "training"is priceless,sometimes just spending the time learning is more rewarding than making money,excellent post plainbill,top man
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: Top Half of Dell E151FPb Darker
I agree MM
It can often be frustarting, but it's worth it in the end. And yes, schematics can be dodgy. Better to look at the circuit and apply your knowledge. In the case of transistors and fet's, the polarities will tell you which way it should fit in the circuit.
Quick note: since the monitor does not have brightness control, that would indicate a problem with the inverter IC.Heaven, is a place where all IC's are DIP.Comment

Re: Top Half of Dell E151FPb Darker
Sweet mother of Jesus! No wonder everything is all wrong! The board is from a Dell E153FPC!!!! Does anyone know what are the FET's that drive the inverter circuit? Because I was obviously using the wrong ones!!! Or does anyone perhaps have a schematic? My apologies if one is not permitted to make such requests.Heaven, is a place where all IC's are DIP.Comment

This is INSANE!!! The SM I need can be found through this link: http://www.fixya.com/support/t404412...other_response
It's the power board for a E172FPb. The E153FPC uses 8 pin smd fet ic's.Heaven, is a place where all IC's are DIP.Comment

Hi everyone,
Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.
I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:- The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hello everyone,
I have a Dell U3419W Monitor that has some thin stripes on a part of the screen since Tuesday.
This lines cover about a third of the screen and appear for 2 seconds before disappear for another 2 seconds.
This repeats the whole time. I have not opened the case yet cause I had no time, but will try to fix it on this weekend. For me, it looks like a problem on the TCon... Am I right?
Does someone have seen this before?...
