restart problem with Bush LED TV

[Mikeyboy2007]

Hi guys ive been asked to look at this tv by a neighbour. She said to me that she called the argos helpline as that is where she purchased from and they said it was because she shut the tv off while the Netflix app was open. When you switch the tv on it goes to a blue screen for 5 -10 seconds then shuts off and back on continously. The red LED on the front blink on and off repeatedly through the whole thing. Could anyone point me in the right direction for repair ? I have attached pictures of the 2 boards in the tv.

It's probably corrupted firmware. Maybe try flashing new firmware with USB stick. Vestel has a lot of issues with firmware corruption.

Ive tried looking for the firmware Via google. Cant seem to find it.

No longer under warranty? It will probably need a new main board then.

Try and tell your neighbour not to buy another Vestel again, it's throw away garbage.

Might be worth checking some PSU voltages, perhaps try pressing down on the CPU see if it's got a cold joint on the BGA. Check LDOs: U14, U6.

No Tim unfortunatly it was 1 month out of warranty when it happened. I will try to search for firmware again. Thanks.

I think she'd have a case under SOGA, it's unreasonable to expect a TV to only last 13 months. Argos needs to destroy these Vestel pieces of junk and send them back to the hell they came from.

They're built for the consumer society. Built to fail. Nothing else.

Re: restart problem with Bush LED TV

got new board through and installed in TV and still not working, tv doesnt shut off like before but still have no picture, changed Tcon board and still the same, could it be a possible faulty panel ?

Re: restart problem with Bush LED TV

So what new board did you try ?
what voltages have u checked so far ?

Re: restart problem with Bush LED TV

Be aware that there are many board variants and you need the exact one. Also, you should still have at least the original symptoms (shutting off) if the main board was good and something else is causing the fault... the fact that you don't would indicate the main board you have received is bad.

Ive had trouble trying different 17MB95 boards....

It MUST be the exact same one Ive found from the same sub-make (Alba, Hitachi etc) to work, and have the same paper label number.
I fitted one--and let the smoke out as the panel was a different version to the one it was made for!

Utter Shite, Vestel Vomit!

havnt checked any voltages and the board that has been replaced in it is the exact same board from the exact same TV.

Re: restart problem with Bush LED TV

is it the white label ? and has all the numbers got too match ?

[sordids999]

Re: restart problem with Bush LED TV

yes i try to match up the model of the tv and also the board number and the white label as well due to there being so many differnet versions of vestel boards around
