KevinWhiteJA :

Hi, welcome to Just answer

KevinWhiteJA :

How old is it ?

KevinWhiteJA :

Please tell me its complete model number

Customer:

It's about two years old

Customer:

Btvd91216b

KevinWhiteJA :

Have you tried another socket ? Is the power cable fine ?

Customer:

yep tried in another room but still the same and definitely power because the red led is on

KevinWhiteJA :

OK...the red led indicates power is going to the unit however, as it wont turn on it seems that the problem is with the power board or with the voltage needed by the circuits in the power supply of the unit. A broken or blown diode or resistor serving as bridge or holder of required needed voltage can cause the problem....how good are your DIY skills ?

KevinWhiteJA :

can you take off its rear and check the power board ?

Customer:

I took the back off yesterday but I can't get at any thing because the wire too the screen is too short to get my hands in

KevinWhiteJA :

Basically repairing and solving this problem by yourself is not very easy since some parts inside the unit needs to be tested, replaced,soldered ,screwed....usually the voltage is still in there even when turned off...if you still want to check it yourself...check this Image ...this is the main board which has to be tested/checked

Customer:

I take a look now

KevinWhiteJA :

OK

KevinWhiteJA :

let me know how it goes

Customer:

I know have the back off and away from the screen

KevinWhiteJA :

OK, please check the board for any blown components

Customer:

Ok give me a few mins

KevinWhiteJA :

sure

Customer:

All seems to be fine

KevinWhiteJA :

on the board ?

KevinWhiteJA :

do you have a multimeter ? can you test few things ?

Customer:

Yep and I don't have one

KevinWhiteJA :

OK, a new board will cost around £35...however, these parts are covered under 2 to 5 years of warranty..you will have to check with the manufacturer..you can contact 0844(NNN) NNN-NNNNto book a local repair engineer

Customer:
