No, mine has VES315UNGB - L3 - N52... -
Good morning everybody, as I stated in my first post, it doesn't let me do anything. The pop up is so fast and repeating that it doesn't let you even do anything. I can press the menu but when the menu opens, it closes in the blink of an eye because the low storages message pops again.
A fellow local technician said it needs an update through USB, typical for Vestel.Leave a comment:

Toshiba 32LA2063DG
Hello, I have this Android Toshiba TV that has a popup that doesn't let me use the TV anymore. It says that "the storage is full". Nothing works because of this. I need help fixing this problem. It has a Vestel mainboard 17MB171. What can be done? Resetting it will work I guess but how can I do this? -

Oh ok, PQ205 is an SM3308NSQA, I suppose PS206 is the same?...Leave a comment:

You mean I have to replace these 3 ICs? The right one is burned beyond recognition....Leave a comment:

Re: Lenovo S145 (GS440&GS540 NMC511 REV 1.0) No power
I forgot to mention that the 20V input goes to PQ201 (SM4377) but it has 0V in it's output so PQ202 (F2 VUA) is also with 0V in the input-output. Which of the two needs replacement? PQ201 or PQ202?...Leave a comment:

Lenovo S145 (GS440&GS540 NMC511 REV 1.0) No power
Hi everyone, this laptop once the PSU is inserted the power led lights up for a milisecond.
PQ206 has melted so the markings are unknown to me.
I need the schematic.
Can anyone help me get this motherboard fixed?
Thanks in advance....Last edited by WhiteWolfHellas; 10-13-2023, 11:29 AM. -
Dell Inpiron 3521 (LA-9104P)
Hello, I have a Dell with motherboard VAWOO LA-9104P REV 1.0
I tried to upload a video with the symptom here but it fails to upload, so I will describe what it does.
Pressing the power button makes the fan spin for a second and then stop. The power leds also lights up for a second before it turns off.
I have 19.5V, 3.3V and 5V present, but my spi chip UH6 has 0V.
Following the schematic, I see that PU200 has 19.5Vin as well as output voltages.
Can it be a bad bios chip then?
I have checked the +3VLP and it is present....Last edited by WhiteWolfHellas; 10-07-2023, 02:13 AM. -

Re: Toshiba 32AV933G stuck on stby
I just injected 3,3V with my bench PSU to PS_ON and 12V and 24V appeared, so my PSU is OK. The problem is the main board?...Leave a comment:

Re: Toshiba 32AV933G stuck on stby
I thought about this too. Do you think the 25Q64 needs programming?...Leave a comment:

JVC LT-48K780 firmware update
Hello, I have a JVC LT-48K780
Main board: 17MB211
Panel: VES480UNDS-2D-N12
I have backlight but the screen is black. I don't see any shorts on the panel's long t-con board so does this mean that the fault is in the firmware? -
Re: Sony KDL-50W800C BLInk 5 times
Any chance anyone has repaired this T-Con for future reference? What chip goes bad similar to ISL9860?Leave a comment:
