Recommend me some site where I can ask for help with identification of some component on PCB of power supply of my Benq BL2710Pt monitor. That fucker managed to blow up right in place where it had marking. I have no one to ask. I found one small piece of that marking plate, but still it's hard to identify it.

Is the PCB external like an adapter? It might be easier to find a new adapter with same voltage and current rating.
Benjamin Thompson
No, unfortunately it's internal adapter.

can you zoom out more ?
Lucas Moore
Can't upload images here, because they are too heavy.

Go to ebay/aliwhatever and search for these boards. If you are lucky you can find good photos where you can read the ICs number.
David Edwards
Might be a stab in the dark but have you tried asking the customer support?
Cooper Miller
Thanks for your effort. This might be it.
I'll try. But yesterday I tried to google any part for this monitor and couldn't find anything. I'll try again today.
I don't think they will help with this, but I'm not loosing anything, so I'll try this too.
Eli King
wtf how did that happen? I have never seen an exposed die after a IC burned:p
Ryder Ortiz
Thunderbolt.
Austin Peterson
pretty sure it is flyback converter and that IC is switching controller
Brandon Williams
That sounds about right, given that it's around power components and presumably a flyback xfmr...
Austin Allen
You should get out a bit more.
Angel Butler
Don't bother trying to fix at component level. You have no idea what damage has been wrought in that circuit board. Whatever killed the chip may still be there and replacing the chip will just sacrifice it to the smoke gods.
Better to buy a new/used board assembly.
Most monitor shops will have stocks of common parts.
Been there and done that.
Carson Cooper
I can't find it for this monitor. I don't know why. I searched on ebay and aliexpress but still don't see that PSU board.
Monitor is BL2710PT, you can try to find it if you know other places to look.

Also, I'm not in US, it's quite cheap to have it resoldered here. Like 20-30$.
Kevin Fisher
Thanks for your help. Now with help of anons in this thread I'm 99% sure that it's TEA1751T
But what do second and last lines mean? Is it like revision, or date of manufacture?
Nicholas Watson
"12061" could be a date stamp, commonly YYWWD, or 2 digit year, week, day of week
so in the case of 12061, that'd be 2012, week 6, day 1, or February 6, 2012
Nathaniel Morris
Probably that. sometime they explain it on datasheet
Carter Turner
It's probably just a Chinese clone of the TL494 or similar PWM controller IC.
Blake Watson
>$20-30 to solder one component
Holy shit what a rip-off.
Alexander Robinson
it's not for one component. It's 5-6 components + their cost. That is normally enough after thunder.
Isaiah Stewart
>TL494
Gramp, what are you doing here?
Gavin Rivera
The soldering should basically be free. You should have your own iron. All the other components should be very cheap with the possible exception of the transformer and in some circumstances the power MOSFET/IGBT/Thyristor. If the transformer is fucked and it's not some really basic 60Hz 1P1S mains transformer (if it's in an SMPS it's not) then good luck finding another one. You need another coil with the exact same ferrite material, effective core area, and inductance factor then you need to unwind your transformer and find out how many windings, and number of turns and if it's flyback you have to make sure when you put it back in circuit you have the dot ends in the right place or it won't work right.
