Re: Finlux LED 32.7 CTS turns on and off in cycles when plugged in
I picked this firmware

I havent found neither the perfect match firmware to my set, Ive just chosen one that was similar and worked. Actually 3 differents firmwares worked for some degree, but by two of them the tuner didnt function.Re: Finlux LED 32.7 CTS turns on and...B000.zip[/url]

Here are some vestel drivers, the actual one that runs my TV comes from this website.
1 copy the extracted files to a usb stick (there are no other files on the usb stick, at the best its fresh formatted)
2 turn off and remove the cord of the tv from the wall
3 insert the usb stick in the tv
4 plug the cord in
5 turn the tv on either with the remote or with the onboard button of the tv.
6 after 2 minutes it should...

I think that i could have repaired the TV by just flashing a new firmware, but as I heard the weird noises coming from the PSU I was sure that the PSU must be bad.
Maybe it was, maybe it wasnt, but flashing a new firmware was essential, theres no doubt about that.
As a first step I would refresh the software of the TV.

After changing the big caps the tv began to emit friendlier noises, (no clicking), and after a firmware flash it works again.
Everything works perfectly the only problem i have is to tune it with the cable.
I dont get any channels. Not sure though whether its caused by the tv. Maybe there comes no signal on the cable....

Changed the high voltage caps and MUR460 as well, maybe its less noisy, but still produces the same symptoms. Im stucked.Last edited by aerojolly; 11-07-2015, 05:23 AM.

Vestel PSU weirde buzzing sound. Is it okay?
My TV just restarts itself in half minute cycles, and the PSU generates weird sounds in the meanwhile.
I captured it in video, should i pay more attention to my transformer?
Heres the video:

I have checked it already, the measured resistance of all the diodes of the PSU is in my opening post.
This was the first thing i tested, current flew only in one direction, the resistance in the right direction was measured at 484.
I forgot to say that all the measurements were made with one leg out of the circuit.Last edited by aerojolly; 10-16-2015, 01:18 PM.

Finlux LED 32.7 CTS turns on and off in cycles when plugged in
PSU: Vestel 17PW07-2 041111 V2
Mainboard Vestel 17MB70-5P V1 050511
The problem of the TV is that it wont respond neither to the remote control nor to the button on the TV itself, and when its power cord is plugged in, it turns itself on, the red light begins to blink, at the fourth blink the screen turns on, shows white screen, and at the 12th blink the screen goes off again.
In the next cycles it blinks only 7 or 8 times and at the 4th or 5th blinking comes the screen on and after a few blinks goes off again.
A cycle lasts approx. 20 seconds.
I have measured...

Re: New Members - please post your introductions here
hello guys,
im a student who is currently thinking of changing lifepath, and deal with electronics instead of mechanical engineering.
i always repaired smaller electrical problems (revive electric tools, etc), but i would like to understand and repair more complex devices as well.
this forum would be a good opportunity to help me along this way.
thank you
