Re: VESTEL FIRMWARE: Toshiba 32W1333B
which tools would I need, I got a hot air gun somewhere and to be honest, can't make it any worse anyway
Let me take some close up pictures first.
There we go:

Re: VESTEL FIRMWARE: Toshiba 32W1333B
VGH and VGL are both about 740 Ohm against Ground. If I bell it through VGH against VGL it seems to be connected.
Wait a second. Just checked it with a magnifier. I measured VCH instead of VGH. The only one I found on the board sort of similiar to what you said is VGHP and has a value of 48 kOhm.
Just to clarify:
So, VCH and VGL are connected with each of them 740 Ohm against ground. VGHP has 48 kOhm,...Last edited by Magio; 12-22-2019, 12:19 PM.Leave a comment:

I have belled through all available SMD parts against ground and almost all of them seem to be sound. Where can I check the DCDC converter?
What rails do you mean exactly?Leave a comment:

2.2mV on both, assuming I have found the right one. Pretty sure to have measured VGL, not sure if VGH was the correct one though....Leave a comment:

Re: VESTEL FIRMWARE: Toshiba 32W1333B
Thought about the T-Con board though, but replaced the 17MB95M. Is there a specific T-Con Board for this model? Isn't that backlight controller with a fix connection to the LCD panel cable attached?...Leave a comment:

Re: VESTEL FIRMWARE: Toshiba 32W1333B
Oh got the misunderstanding. No there is no image I can see unfortunately, tried with a super bright LED flashlight. When switching programs up and down the backlight becomes brighter and adjusts itself again back to black with less brightness....Leave a comment:

There is no picture to be seen unfortunately. Tried it. I made a picture from what's inside showing all LEDs / Backlight working.
It doesn`t start the update though

Just found out after I reading the flashdrive that previously attached to the TV it had created a folder named "DVR" with all subfolders and files. So obviously the system does something

Let's give it a try. Thank you°!...Leave a comment:

There is no damage. The backlight tries to adjust brightness as well, so I see it going darker. No further reaction though...

I have exactly the same issue with a hitachi 24hyt45u. Replaced all (Schottky) Diodes on the 17IPS61-3 already as their value didn't seem right (different each). Nothing has changed. Further I have replaced the ceramic resistor on the board also, nothing. Might be a software issue as it all turned black, but LED reacts as expected. No OSD is visible though.
Brief summary:[LIST][*]Hitachi 24HYT45u[*]17IPS61-3[*]Vestel 17MB95M (already replaced once)[*]VES236WNVC-2D-N01[/LIST]
