SSI_400_14A01 Rev0.1 Backlight Inverter, Original or Updated Board?

[TrblShtr]

Hey everyone,

A friend of mine's 40" LCD T.V. needs replacement of the backlight inverter which has the infamous black screen no sound issue. I know ebay has the original units (SSI_400_14A01 Rev0.1) available for purchase but before I do, I was wondering if it would be better to purchase the updated version of the board which is basically the same part no. but instead 'Rev0.2'? I've attached a couple of pictures below of the original (left) and the newer board (right) for comparison. Thanks in advance.

Are you certain that the original board has failed or have one of the CCFL tubes failed due to age?

To be honest, I've been going off of youtube videos & online research only. I did manage to pull the board and take a look at it and there were what appear to be burn marks on both sides of the board; the bottom has them (brown blemishes) right under the transformers. Various sources stated that you can check if its the inverter by shining a bright light close to the screen in a dark room and if you are still able to see somewhat of an image, its most likely the inverter; I did try out this quick test and did see an image btw. When I turn the t.v. on, I get no sound and a black screen. Can bad CCFL tubes cause these symptoms as well?

If a single tube fails then it can lead to no backlight. You do say that you can see an image using a bright light so you should have sound as well.

Do the backlights flash very briefly when you turn on the set?

Post pictures of both sides of your existing inverter board.

Have a look at this video

In answer to the original question I would think that Rev 1.0 could be replaced by Rev 2.0 but that's only my thoughs

I see, I had no idea that one tube failing can cause the black screen issue so thanks for pointing that out. As for the sound, I don't have anything hooked up to it like an antenna or anything like that; what I'll try later is to hook up an external source such as my phone to the t.v. and see if I can hear music through the speakers. I'll post the result as well as some pictures of the board once I do. In reference to the backlights flashing briefly, I saw nothing and I even checked with the room pitch black. Thanks again for the video link & your help I appreciate it! I'll be back later with my findings.

What is the full model number of tv? should be on the back cover.

Re: SSI_400_14A01 Rev0.1 Backlight Inverter, Original or Updated Board?

Yep, could be a bad ccfl tube or bad inverter board if you have a multimeter you could do some testing, those inverters fail often, worth a shot to buy one if you can get it reasonably priced. HIGH VOLTAGE WARNING, WHEN POWERED ON THERE CAN BE OVER 1000 VOLTS COMING FROM THE CCFL TUBES, WHICH CAN KILL EASILY.

To insure a match you need to match up the numbers on the yellow sticker.

In response to dick_barton's question, I connected my game console to the t.v. and discovered it does have sound. I posted a couple of pictures of the board below but be warned, the quality of my phone's camera is trash but you can see the brown blemishes on the solder joints on the transformers as well as the back of the board.

The t.v. model no. is: DX-40L261A12 by Dynex.

I do have a multimeter actually, what exactly should I test on the board? I'll definitely be careful and not rush anything as the thought of 1000v zapping through your body is a scary thought!

I'll make sure to match the numbers digit by digit; if anything, I'll go for the updated version of the board (Rev0.2)

I really appreciate the help guys, thanks very much! Here are some pictures of the board, sorry about the crappy picture quality!

****EDIT******

I apologize but I had a brain fart with the previous post, the model number for the t.v. is wrong. The correct model number is: DX-40L150A11.

Thanks.

Hard to tell which way to go, it's a 40 inch Dynex, they're wanting 40 or more bucks for them on ebay, seems very high, then the question is will it last very long, there's a repair kit there but it's still 30 bucks but free shipping: http://www.tvrepairkit.info/samsung-...rter-component

Re: SSI_400_14A01 Rev0.1 Backlight Inverter, Original or Updated Board?

Well these will all work, I don't know why they're wanting so much for them tho: LJ97-02098E, LJ97-02098A, LJ97-02098F, LJ97-02098C, LJ97-02098B

It did cross my mind to purchase a repair kit for the board but it looks like alot of intricate work; I mean I'm decent at soldering but if I can take an easier route then why not.

I found this one which I'm 99.9% sure will fit but it looks like the seller didn't bother to find what other boards & t.v.'s it will fit: https://www.ebay.com/itm/New-Inverte...MAAOSwqgRZuNpl

Ok, it may work, it looks different than the first one, do the first 5 or 6 sticker numbers match? Maybe contact the seller and get more info.

Its hard to see the sticker numbers on the sellers images so I went ahead and messaged him. That board in particular that looks different is the one I'm seeking info on in this thread. Its labeled as an "upgrade" to the original 14A01 REV0.1 board which looks exactly the same, screw holes and all except for the electronics on the board are obviously different. The reason I'm sure it will work is because I searched part no. LJ97-02098E which is one of the part numbers you listed a couple of posts ago and this updated version also shows up as a replacement.

i have spare ones but wrong country .

For a moment there I thought I was set until I saw you were in another country!

Thanks.
