Re: Panasonic TH-50PZ800A right side of screen black

Thanks everyone, finally got it going. I suspect that the T-con board was replaced. It has hand written numbers on it! And suspect that they had the ribbon cables in crooked. They were indented on the corners! But all fixed now and been running for a few hours.

Now to return a working TV...

Really appreciate your guidance and patience with me

Re: Panasonic TH-50PZ800A right side of screen black

Hi All, I seem to be taking one step forward and three back! I have reseated all cables. Now I get 6 blinking red power LED flashes.

Hi Biruslapio - as requested I have uploaded more photos. The cables look like they have been seated correctly. But I am wondering if I have damaged them due to locking them in on the 1st instance incorrectly. And each time I try it is hit and miss

I really appreciate all your assistance and support to date....

Re: Panasonic TH-50PZ800A right side of screen black

Hi, I cleaned to connectors and cables, put it all back together.
Now there is a pink strip on the left and right sides and black lines on the right side as per the picture.
I couldn't get free to air TV to work either via coaxial, just displays No Signal. Coax cables works on another TV.
I have checked that all cables are seated correctly.

What have I done? ...

Hi Biruslapio. There is a fair bit of dust on the bridging cables. I have not removed or cleaned them as yet. The look to be seated correctly. I carefully removed the AV/Connector board to get to the T-con board. Pictures attached.

Which is the LVDS cable?

Many thanks...

Thanks Biruslapio. Will pop the back off and have a look. Here are the pictures to show the fault condition and then it clears intermittently!!...

Hi Andrew. Here at the pictures. One with the fault, and the 2nd where it is OK. The other post suggests to check cables. Will do that tomorrow.

Thanks...

Panasonic TH-50PZ800A right side of screen black

Hi,

A friend has a Panasonic TH-50PZ800A TV where the right hand side is black. It happens intermittently.

I thought that it may be the buffer boards, but to my understanding, this would effect either upper or lower screen?

Any assistance would be greatly appreciated.

Thanks

Re: VIVO 40" LCD (LTV40FHD) No Picture

Hi. I have the same issue on the same caps. Looks like it has been resoldered and real shonky at that!

The caps look burnt, and I can't see values on them. Also difficult to find a schematic.

Any idea how I can find the cap values, so I can replace them?

Thanks
