Power board vestel 17ips61-3 | Flash Red and Blue

[GnobarEl]

Hello all,
I have a TV with a vestel 17ips61-3 power supply and when I turn it on it doesn't display any image. However, I can see the power blue LED and after sometime or when I press any button on the remote control, the LED starts flashing from RED to BLUE and remains blinking alternatively for several seconds.
I've measure all CAPS and they look fine. All the values are in the acceptable range of each capacitor.

I'm not really sure how to test the diods, any feedback? Even so, the TV have power, I'm not sure if the issue can be related with them or with the power board.

Any tips / advice? Anything I can do to debug it?

Thanks.

Best Regards!

Hi, I'm sorry, but I'm not exactly understanding... I'm more a coding guy and not HW.
anyway, I attached all the pictures I have from the "power board" and the "green board".

I think the number you are referring is this:
23155823 01385
V030f L9 MD
16/11 - 4/12 - 1

The TV is a white brand and doesn't have a brand.

Hope it helps, if not, tell me what you need until I get it!
Anything you need to help me get this tv alive again.

Thanks.

under the sticker i have highlighted in red there is a number printed onto the pcb as this could be a firmware issue we need to see what the mainboard number is

Oh! Shame on me, I looked several times for that sticker but I couldn't see the number. Soon as I get home I will give a look.

I don't know if this will help, but anyway.
This TV used to take a long time to show image. Around 30minutes, since its placed on a moisture place, I always thought that it could have some humidity inside and it needed to heat first before showing any image.

Recently, it doesn't show any image. As I described, I can turn on (red light) and it starts blinking between red and blue.

I measure the CAPS and Diodes, and they all look good. Even so, if you need me to take some additional measures, please let me know.

Best Regards,

Have you tested the voltages on the psu are they all ok? have you got a schematic for the psu?

Hello @vinceroger69,

the number is: 17MB55

I checked the power supply, specially on the C2 connector and everything looks fine. I got 22v and 11v. Looks fine to me. I start to suspect the problem is relates with the main board.

Do you have any thoughts? Anything I can do?

Thanks.

Thank you both for the support. The files are a .scr and .bin file. Should I flash the bin file on a USB drive?
Do you have any documentation on how I can use it to flash the TV?

Thanks.

1. Format a stick with FAT32 (max. 4Gb)
2. Unzip. You get 2 files
3. Copy the 2 files to the stick (directly, without folder)
4. Insert the stick into usb-tv
5. Press and HOLD the OK key on the remote control (remote control to the TV).
6. Plug the TV into the socket (220v).
7. When the stb LED on the TV flashes quickly release the OK key.
8. Wait until the TV restarts itself and turns on (3-5 MIN.).
9. Remove the stick.

Later on soon as I get home I will try it.

Hope to give you good news lets see. If it doesn't work, its a HW failure!

Thanks again!

Hello all,

unfortunently it still the same after flash. No image or any backlight.
I don't think thats a power supply issue or, now we know, its not a FW issue. Every time I press the buttons of the remote the TV have some "normal" behavior. Looks the issue is related with the image itself.

Any more tips? Now its a challenge to have it fixed!

Thanks for your support.
