Identification Problem?

[Neotheone]

Hi, can anyone give any assistance with this item - having problems finding out what it is as one is burnt out on board.

looks like id WG9J or W89J ?

Picture not the best but should be ok for id process.

this is from an unbranded 32" lcd tv but matches Technika type and it off the main board L2M08 2008.12.26.

any assistance would be great.

Re: Identification Problem?

If you search for the SMD code "G9" in here instead of WG9J, you'll get 9 different products but only one of them has 3 pins, which is of type BF 767, manufacturer is either Siemens or Philips.

Then if you go and search for BF767 in this page, you will indeed find Siemens and Philips datasheets for BF767.

This Philips one for example, which is a PNP Silicon Planar Transistor BTW, is indeed used in TV tuners:

Re: Identification Problem?

it is definitely WG9J and definitely some kind of planar surface-mount transistor

if it was me, I would replace every electrolytic cap in this TV, those transistors don't burn for no reason!

Re: Identification Problem?

Well I am slightly confused, when trying to locate to order some of these the identification is not showing up, can find some types but unsure of the values needed any pointers from the technically minded at badcaps?

Re: Identification Problem?

post high resolution photos of the board, often times problems like bad capacitors will be obvious

Re: Identification Problem?

Ive checked some capacitors and tried the black resister on the back but no luck yet

Re: Identification Problem?

you need to post these questions to the badcaps TV subforum - that is where the TV gurus are on here!
