Re: sanyo no back ligth

You may want to bend the legs up a bit, it looks like the right leg is almost touching the pad close to it, otherwise, you got it right.

Re: sanyo no back ligth

Ok, like this?

Re: sanyo no back ligth

I recommend the resistor in case the person accidentally short the lead to the chassis, that way the resistor will limit the current, base on this person experience, you are right, he should use the resistor.

Re: sanyo no back ligth

I always use it for safety just in case. Sometimes they rely on the main board using a resistor...

Re: sanyo no back ligth

There is Base resistor in series with the Base, and also a resistor between Base and Ground on the inverter board. Unless this is really badly designed board.

Re: sanyo no back ligth

It wouldn't limit current, if it is going straight into the base of a transistor, for example.

Re: sanyo no back ligth

By the way, IF you do not have the resistor, you can still use that Diode, but you will have the put the banded side on pin 3 instead.

Re: sanyo no back ligth

At least he has it on the right pins as I request. Make sure to tell us the color code of the resistor before you solder the resistor in place.

Re: sanyo no back ligth

I am not laughing, I am just making sure it is the right component. We all make honest mistakes.

Re: sanyo no back ligth

hey don't laughg. iam learning.

Re: sanyo no back ligth

That looks like a diode, not a resistor?

Re: sanyo no back ligth

is this what you mean?

Re: sanyo no back ligth

i will try

Re: sanyo no back ligth

OK, leave the TV unplugged.
Put the connector on CN2 back in place.
Do not have the connector plug in to the C6.
Get 1K any wattage will do, connect the resistor between PIN1 (5vstby) and pin3 (BL_ON) of CN6.
Plug the TV into the outlet, hit the power switch, the backlights should come on.

Re: sanyo no back ligth

on cn2 i am getting gnd,0,5v,0,0,12.5v,12.5v,12.5v,12.5v,0,0,15.v,15.v,3.2v

Re: sanyo no back ligth

was a piece of dust.

Re: sanyo no back ligth

ok. i do that now

Re: sanyo no back ligth

Pic is very good one of the best I have seen for some time.
If you pan along the white line in the middle to the hole
Just below the hole there are 3 resistors and next to them
C902 Just below that there is an odd bit of solder?
May not be doing any harm but can you check it out.

Re: sanyo no back ligth

check the fuse on the t-con, it is goog. iam going to put everything back together and do the test.

Re: sanyo no back ligth

is this good?
