Question about Sharp LC32D62U 32 in. LCD HDTV

1 Answer

Color lines running down the screen

I have a sharp LC32D62U TV, starting yesterday i am seeing yellow blue and red lines running down all along the panel. My extended warranty ran out in 2011, and I have already done all the standard no duh checking. Switched cables, tried different systems, PC, PS3, TV, when its on a blank channel/input there are only blue lines, anything else i see the lines running down the screen. What should I do?

That can be caused by either the Tcon or the panel itself may have an issue. The TCon is most likely though. Your audio works correct right? I would try a new TCon you can get them from

    Im not familiar with what a Tcon is exactly? But you are correct the audio itself works perfectly fine. I will contact them and see how much it will run me. Will report back when its solved. You wouldnt happen to have a link handy about changing a Tcon? I will Google it too. Thanks again

    So someone from tvrepairworld corroborated what you have told me that it sounds like a TCON board issue. I am asking for specifics as to model, serial, etc that i need to ensure that match my TV. If so then i will order it and try it. If it solves the problem i will update here. Thank you again for pointing me in the right direction.

    I would match the numbers directly from the circuit board itself as various Tcons were used based on the panel used in your version .

  • Nabeel Akhtar Jan 12, 2013

    You have been a great help. I have located the part number/serial number off the TCON board, found some websites that are selling it online. I am waiting until tvrepairworld returns with a price for me. Thanks again...will keep you posted.

    Glad that I could assist with th issue

  • Nabeel Akhtar Jan 19, 2013

    So I received the new TCON board today and promptly went to install it. I went and installed it. Secured everything exactly the same way as before. The TV now turns on, solid green power light for about 5 seconds or so then shuts off. I get three blinking lights on the OPC, then the power and OPC blink three times in sync repetitively.

  • Nabeel Akhtar Jan 19, 2013

    Okay update, now the power and OPC lights blink twice, followed by the OPC light blinking 3 times

  • Nabeel Akhtar Jan 21, 2013

    Update: The rep from Tvrepairworld just emailed me asked me to reseat all the cables attached to the tcon board and anything else that i may have missed. Going to do that now and update once its done.

  • Nabeel Akhtar Jan 21, 2013

    Update: I put my old TCON board back in to make sure the cables arent the things that are messed up. The TV turns on fine, and stays on, no blinking lights or anything.

  • Nabeel Akhtar Jan 28, 2013


  • Nabeel Akhtar Feb 19, 2013

    Just an update for those following. Sonny has been insanely helpful at trying to troubleshoot this problem. Unfortunately the tcon board didnt work and i have shipped it back. I reached out to Sharp themselves, and they referred me to a local repair shop. I dont know how much it'll cost though as it is 50 just to have it looked at because it is out of warranty.

SOURCE: turn off closed caption on input(component) on Sharp Aquos 42"

I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

SOURCE: Sharp Aquos LC-32B20E wont display a PS3 output via HDMI


I too went through this problem.

Step 1 - Plug in your "composite" cables and the HDMI cable to the PS3. Obviously, the "composite" cable are the ones that came with the system. You need to start with them as the default connector.

Step 2 - After connecting the "composite" cable and the HDMI cable to the PS3, connect the other ends to your TV.

Step 3 - Power on your PS3

Step 4 - Select display settings-->video output settings

Step 5 - Change from the current video cables to HDMI. (Your tv has different inputs. When you switch to HDMI in the PS3, you will have to switch your TV to the HDMI input that it is connected to, to get a picture)

Step 6 - Be quick, the PS3 will display a "test" for 30 seconds. You need to switch your tv to the correct HDMI input and press "X" on your controller to accept the change.

Let me know how this works for you.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....

Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.


Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

I'm hoping this is just the lamp.

try to set the convergance if you cant you can adjust the color tubes from inside the tv but have to be very careful to do this. There is actually only 3 colors in the tv red, blue green so I would say your blue and green need lined up
