Facing TV Problems? Ask a TV Technician.
Thank you for posting your question on Just Answer! I will be happy to help you with this problem.
make sure this is on all inputs VCR DVD etc.. if it is then
Friend this unit has a corrupted processor on the main board, its not being told to turn on and off, video processing. The main board is the unit that has the inputs for all of your external toys DVD,VCR so forth, you will have to open unit and read the name on the board, so we know who makes it and get the part number also.
These are some part stores, CALL THEM IF POSSIBLE always check with manufacturer , And you may need the name of the part and its part number off the part itself
Normally the controller board, if is bad there will be a picture but a bad one, Missing parts of the screen or lines, This is what the controller or T-conn board does,
Disconnect the T-conn board, by removing the LVDS cable turn set on does screen light?
I haven't had the opportunity to test the recomendantions. If I disconnect the cable and the screen lights up what will this tell me? the inverter board is independently connected to the ccfl should light the screen even with the controller board disconnected. I believe from the beginng of the questions that either the controller or tunner board might be defective. The reason to post the question is to isolate which board could be, so I don't have to buy two boards. Give me some time to test your recomendations; hopefully today I will be able to test your recomendation.
LVDS cable and main board is suspect.
Ok. Good luck friend
You are absolutely correct,
If you have any more questions I'm here friend
Rick, I received the main board and installed it but the same issue is present. Any other recomendations?
Rick; just wanted to tell you that the tv is working. If you go back to my original troubleshooting I always taught it was this board.
".....I believe it could be the lcd controller board since the other two boards are the power supply and the big tunner board with all the inputs (hdmi, etc); what you guys think?..."
I just needed a way to test this and that's when I came to this forum. I know you like using the blame game since most people asking you questions are technically challenge but this was not the case. You did show me a way of making some extra money by joining justanswer. I just wished that instead of spending the $18 on you, the $65 on the wrong board, I would have just spend $60 for the right board; plus your $18.
Im happy for you friend, And i am sorry for the extra Cash you had to spend, But as you should understand these errors you were having are hard to isolate, Because main board T-conn And LVDS are all in series with each other, But you have mentioned a key problem in your last message, I think even you missed this one, You said you seen lines before going Black, this would have been key in the troubleshooting of this set. I think i said some of the T-conn issues are lines and so forth, But let me stop i wont play the blame game
I am Happy for ya, And yes take the test we need good techs we are swamped with todays technology.
Let's see how it goes on my next quest; I will keep you in mind.
