Question about Televison & Video

1 Answer

LC45D40U Sharp I am re-asking this question since I mis-stated the symptom. This TV has flickering scan lines on the upper half of the screen. Otherwise the picture and sound are normal. I also noticed on the mail board there are 2 red led's 1 is solid red and the other is flashing red. Normal?? I was thinking that the T-Con board is the culprit for this Scan line issue.

Hi


Thanks for using FixYa. Yes you are absolutely right it is either the T-con board in the unit has gone bad and/or it is not getting the required 12vdc from the power supply unit. If you have knowledge of internal circuitry of the unit then you can open the back of the unit and check the T-con board which is the last board before the LCD panel. Usually it is available with the LCD Panel. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

What is causing vertical colored lines on the left 25% of my Sharp Aquos display?


Bad TCON board or Damaged screen. You can try and replace the TCON "Timing Control Board" and see if that helps. Replacing the Screen itself is very expensive and normally about half of what the unit cost new. Here is a video to give you a clue on how to do so, it is pretty easy when you know which board to replace.

MY SHARP AQUOS 70" tv STARTED HAVING DARK SHADOWS ACROS 1/2 OF THE SCREEN, THE OTHER HALF OF THE SCREEN IS FINE. DO I HAVE A hdmi INPUT PROBLEM OR IS THERE A TV DEFECT?


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I replaced the T-con board in my LN46A650 LCD TV and still having the same problem, what else could it be? The capacitors are in good condition.


What is the issue with the TV? A defective T-Con board symptoms are half screen image and strange colors. Often lines in the screen are not the T-Con, but a bad LCD panel. A good supplier of Samsung parts is Tri-State Module. You can ask their technicians for advice as well. Good luck.

SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK


You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!
