Logik LCXW32HD1-Standby Transformer Problems

Hello,

Was there info. on the backer reminding you about the opto? do you now have 5v after the tx?

Andy

If you do have 5v, try using the remote (that looks a lot like a Panasonic, doesn't it? :) )

Hi Andy

Thanks for the reply, I did try the remote with no joy.

I also took the parts (u2, c22 & db1) and put them into the damaged board I bought from flebay, this gave exactly the same fault....Could there be a chance that I have blown FSD200 again as I initally put U4 in the wrong way round? Putting it the wrong way round gave me all the flashing control panel lights.

Thanks for any help in advance.

Hi

I have answered my own question and put another (know to work) fsd 200 in and the tv is still the same, the standby light seems to be very dull..

Is there anyway of checking the remote is working correctly?

[Ohm Supplies]

Was it on the backer about the opto or can you tell me the optop type?

[scooby-doo]

Sorry to sound Dumb Andy, I do not understand what you mean.

[Ohm Supplies]

U4,

What type is fitted (the markings on top) and did the backer that came with the kit say anything about U4?

Hi

Its a sharp PC817,

I have just checked some of the voltages and I am getting about 3v from the 5v pins and 1.6v from the 3.3v pins, if that helps any

[Ohm Supplies]

did the backer that came with the kit say anything about U4?

turn the board over with just the supply and tell me the voltage on the 2 points in between C55 and C45. just that voltage please

Hi

I am getting 5.10v from the place you mention

[Ohm Supplies]

Good,

did the backer that came with the kit say anything about U4?

[scooby-doo]

No mate I cant say I remeber seeing anything about U4, I didnt change U4 from the board that I got from Flebay. Andf I am getting exactly the same fault

Just to add that if I turn the board back over and check the voltages from the 10pin connector to the right at the bottom of the board this is the readings I get

GND=0v
5VM=0v
GND=0v
5v=0v
GND=0v
12v=0v
-12v=0v
GND=0v
5vs=5.10v
STB=1.8v

[Ohm Supplies]

If you have 5v from the point I gave then the orignal fault of a blown 5v supply and the tx problem is solved. If the opto (information is on the backer) was the wrong way round them 15v has gone down the 5v line and onto the scaler board,  it depends on what its damaged its done however it doesn't always damage the board enough to make it B.E.R. but sometimes the front button set won't work,

Did you get the board from fea-bay or the whole set?

Hi Andy
I have the original board and the board I have from flebay.

After I screwed up the original board I removed some of the new parts and fitted them to the flebay board, this did not include changing U4 so the flebay board has still got the original U4 in it as I thought I might of blown this too by putting it in the wrong way round in the original board

Do you think I should change U4 on the flebay board, and can I interchange it with either U5, U7 off the original board.

Getting a bit confused now,

Has a psu been in the set and switched on with the opto the wrong way round?
