ASUS RT-AX88U router DEAD
Hi Can anyone help identify this component pls
The[B] Asus RT-AX88U router[/B] is dead & fault finding brings it to a DC to DC convertor. 3.3v goes in, but nothing comes out. The IC is marked "[B]3002 0ST1[/B]"
There is a 2nd working small IC marked "[B]3001 0gt1[/B]" that converts 3.3v to 1.8v, both power separate CPu's on the board.
I have also searched for a schematic for it, to no avail.Hi Can anyone help identify this component pls

@dskall
Thats a good idea.
ill see how it goes over the next few days as looks like it maybe fixed now.
No way of knowing for sure without soak testing it.Leave a comment:

Re: Samsung 3DTV UE46EH6030 fault
Quick update>
Spent some time going over the board with the soldering iron, covering anything that looked slightly suspicious.
Put the TV back together and fired it up. ....
So far it been running for the past 2.5hrs with no problems at all.
Ill still soak test it as its frustrating not knowing exactly what the fault is/was, but for now looks like it possibly fixed.
Thank you to everyone for your help.

Samsung 3DTV UE46EH6030 fault
The psu is a BN44-00552A.
The Tv hasnt been used a while and only had light usage when bought.
[B][U]The Fault>[/U][/B]
The Tv works perfectly when first powered up, however after about 10=50mins,
it shuts down the repeatedly reboots its self. When left for a time, its works again for another 10-15mins
Im not a high end engineer so the basics only were checked.
I figured it was a heat related fault which possibly stemmed from either a
a dry joint or swollen caps, both of which look good visually on the PSU
Any help... -

I got the F/w from Toshiba via email as i it wasn't available online to download.
They will reply with full instructions and a temporary (valid for only 7 days) download link of the firmware.

When you email them , save yourself some time & include a photo of the entire rating label on the rear of the TV, as they will request it if not included.

Re: Back light change
I noticed today that the Led strips A and C at first glance look the same, however the LED positions are slightly offset by about 5mm. This im guessing is what must differentiate between them.Leave a comment:

Vestel Back light change,marked as A. B & C
Im changing the backlights on a TV which has already been stripped by someone else.
The new replacement backlights have arrived & are marked as A. B & C .. However i have no way of knowing if i have to put them in a specific order.
Can someone tell me what A,.B & C represent on LED TV back lights.
For reference, the Tv is a Hitachi 42"Last edited by josweet; 12-22-2021, 04:39 PM. -
Re: Toshiba 40L7355D
Final update>
TV WORKING !
@diif, you were correct in diagnosing it was a f/w fault.
I couldn't find the firmware online so emailed Toshiba who sent me the correct file., however when updating the TV it would always fail at 64%.
The official F/w consists of 3 files> 1 update, 1 bin file (firmware) & one Eboot file.
To get around the 64% fail simply remove the eboot file leaving the ".bin" and "update" files. The TV will update as it should and voila, job done.
Hope this helps som...Last edited by josweet; 07-19-2020, 02:39 PM.Leave a comment:
