Question about Samsung Televison & Video

1 Answer

Samsung HPS4233X/XAA No Video I have a 42? Samsung Plasma TV. Model HPS4233X/XAA. I purchased it in 2006. The problem started with a lose of (video) picture. The raster was there, but blotchy. Sound was ok. Now the picture (raster) is black, sound remains ok. I believe the problem may be in the Main logic board. But it?s just a guess. I was a TV tech for RCA back in 1969? Thank you for any possible help

    No, unfortunately I did not purchase the TV with an American Express card. However, it seems you’ve confirmed that I’m on the right track with thinking that it’s Logic main. Now, All I have to do is find it and hope it doesn’t cost more than a new TV would. The part number on the Logic main board is LJ41- 04461A. Would you happen to know where I would be able to purchase one?

    The only other board I can think of that may cause this effect could possibly be LJ92-01346A. I don’t know the name of the board, it seems that every board in my set is called a “Main”.

    I have a feeling that I’m going to need more of your help before this set is repaired. However, it’s getting late, so if possible I would like to continue tomorrow in the P.M. . Although, if you do know where I can purchase the Logic Main LJ41- 04461A board please let me know now.

    Thanks so much for your help Tim.

Sounds like it is definitely a logic board issue, it is very hard to diagnose this type of problem remotely. You say its about two years old, I take it you don't have any type of extended warranty and didn't purchase the TV with an American Express card? The reason I ask about the card is they automatically extend the warranty of electronics to 5 years.

Most likely a logic board issue, as long as you've checked the voltage and it appears normal then there really is not much left besides the logic board or a piece thereof.

Hope this helps,

    Luckily for you that is a fairly common board, for example it can be found at:

    You may want to call Samsung to see if there are any places in your area that sell it, it's always nice to deal with someone locally just in case you end up having to swap it for a different part or return it in general.

    Their number is 800-726-7864, if you keep hitting 0 at the prompts you will be connected to a live person. Their "Tier 2" support is there from 9 AM - 9 PM EST. Tier 2 techs, as you may know, are the people who actually work hands-on with the machine so they can also verify that the part is what you will need.

    Hope this helps!

Tv not clear at all for a plasma

Before thinking of your TV problem, take a DVD player and then play it to see if the same problem occurs.
Next suspection is the Y board and buffers which affect video quality when they are going to be defective.

Samsung Plasma 42" TV - 2006

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.
