Vestel 17mb61-2 Firmware Problem

[ducky29]

Hello! I am trying to fix a F&U Tv ( Vestel boards).
Led is flashing and the screen dosen't turn on.
PSU 17pw25-3
MainBoard 17mb61-2
I checked the diodes and none of em is shorted ,also checked capacitors.
Everything looks fine.Just to make sure I replaced the PSU but it didn't fix the problem.
I replaced the inverter but It still didn't fix the problem.Also unplugged the buttons panel.
So I thought the last thing to do is to update the firmware.I found the firwmare then I put it into a flash drive and I plugged it in.
I tried pressing OK button or P+ button but none of em worked.
Is there any way else I can update the firmware or maybe another procedure?
Thank you!

Firstly was the replacement Psu the exact match for this Tv and I dont mean the 17pw25 part number I mean every little part number on the Psu ?

Yes it was exactly the same part.
I just left the tv on for about an hour and the led stopped blinking.

Ok, one thing is if you put the incorrect Psu (must be for that model and board!) in it will cause your fault. What firmware you have also got the Mboot folder ?

I only got the bin file(17mb61-2.BIN).I also got 17mb62 firmware but I don't think it can help me.(mboot.bin mb62_en.bin and usb_auto_update_mb62.txt)

no need mboot.bin is enough usb_auto_update.... and ...mb61.bin ...., put these two files directly to USB stick without archive or folders, disconnect the TV from the mains supply, insert the USB stick, press the OK button and holding the remote control, the TV is connected to the mains, the OK button is released when the front LED starts flashing rapidly, expect about 1-2 minutes and the TV will start one of the first installation, the display is important to tell the type of TV you, success
