Re: Toshiba 46rv350u No backlight, No picture but has sound
Hi, I am an automotive tech, so me too not a TV specialist.
But on my toshiba 40 inch found fuses f101 and f102 blown/open, invertor board.
No backlight and no hope to fix it. Parts are simply not available.

Re: Toshiba 40E200U1 no picture problem !
So, in essence, this thread is dead in the water.
Thx again to all who participated, but this LCD TV is not worth our time to continue any longer.Leave a comment:

Re: Toshiba 40E200U1 no picture problem !
Well. this thread took a un conventional turn.
I made a mistake, which probably saved me many man hours to say the least.
I would first like to thank everyone who chimed in to help. Very much appreciated.
When I removed the invertor board, I unknowingly thought the invertor to CCFL strip was one and the same, so once I had done some basic PCB test on it, and replaced fuses f101 and f102, I realized the black strip for the CCFL's were not engaging the strip.
So I had to strip down...Leave a comment:

Yes, that is indeed the exact same board. However, every link I hit is across the pond. UK. If push comes to shove, I will pay the extra for overseas shipping.
Again, thx.Leave a comment:

Re: Toshiba 40E200U1 no picture problem !
Ok, Thx reece.
So I will not focus on the transformers and again thx for seeing the lacking tabs for the CCFL's on the other 12AO1 board. I missed that. I did not count them. Should have been the first I should have done.
Had I done so, I would not have mentioned that. Your reply was very helpful.
If you are referring to the fuses I mentioned for microwaves, I do believe they are slow blow also, hence the hefty price tag.
Something like this was my idea, since the leads are already...Leave a comment:

@Bud and VinceRoger.
Yes that is my board. The transformers read as follows
M LT-4014-1 followed by UO 103l C Y
I linked one here.

I read the thread Reece linked to. I definitely don't want to have to go through all that.
He fell on one very fussy board. I have a feeling mine is the exact same thing.
He was very patient. Hope he likes his new...Leave a comment:

Re: Toshiba 40E200U1 no picture problem !
Oh, plz don't laugh at my soldering job or at my smart multimeter.
Although I do like that funky little multimeter. It great for around the house work like this.
So, back to the inv board. I scoured the net for a replacement board, they are very hard to come by. Everyone is out of stock or they are sold. E-bay has a few left, but I am iffy about the revo 3 boards. They say it is for toshiba models 40E200U. Like I said before, mine is a 40E200U1.
Would the SSI-400-12AO1 revo 3 fit in lieu...Leave a comment:

Thx a bunch all.
I knew I came to the right site. I have been giving advice on another forum. It's called BAT auto. If any of you ever need some automotive advice, come check me out there.
I piggy backed this thread. Should have started my own one, but will continue here.
I checked out a few things on the invertor board and found the micro fuses F101 and F102 to be open.
125v 7a littelfuses I believe.
Now I don't know if this is a good Idea, so I will sound/bounce...Leave a comment:

Re: Toshiba 40E200U1 no picture problem !
Hello, just joined this site.
I am in the process of trying to resurrect my toshiba 40e200u1. I also have the same problem.
No picture, have sound. I have all necessary 24v and 5 volt BL-on and all grounds are good.
I did try the so called flashlight test, can't anything at all.
So, I am assuming the main board and power supply are not in fault as it powers up, stays on, has sound and back-light invertor is getting power, 5 volt signal and ground.
Am I correct to...Leave a comment:
