Panasonic TX-32LZD80 backlight no picture (fixed)

[tom66]

Just picked this up, very local to me. Fault was originally described as no picture and I was about to diagnose a bad inverter until I saw this TV does have a backlight, it's just incredibly dark because it's an IPS panel (very high contrast ratio, but also lower brightness.) I might try increasing the current control on the inverter board to see if the brightness will go up a bit more.

Found the t-con fuse to be blown. Replace that and it worked.

Wish I could make it more glamorous but hard to go wrong with a 32 inch Full HD Panasonic like this, they're very well built. 2008 series. Picture is no where near as good as my PZ80 plasma though! Panel is a Panasonic too; IPS Alpha tech.

Hi Tom

I've got a the exact same model of TV as this and it has the exact same problem. Can you tell me where the T-Con fuse you talk about is located ?

Many thanks

Mark

It's right near the LVDS connector, little black thing. No photos of it, sorry. But it is obvious.

another easy fix, saved from the landfill as well. I wish i could find more sets to repair not much around at the minute.

This was about 6 months ago and it was fixed for a friend who found it on Gumtree like this

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

Still going strong though. Only thing I'm not a fan of is the dim image, OK in a dark room like his though.

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

no i like nice bright clear images my self to be honest is this how these tx-32lzd80 are designed then?

[tom66]

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

Yep, seen a couple others looking the same so figure it's just how they are made. Have not tried to adjust it yet.

Hi guys where did you purchase the replacement fuse as I have the same set with same problem.

Thanks in advance.

CPC stock them. Is there a rating, e.g. 1.3A 32V(T) printed next to the fuse? Or alternatively, a letter on the fuse?

[StephenU]

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

Yes Tom, it's 24v / 1.6A. PN or txt on the comp body is I62 NCC hard to make our as it's so small , 1206 package I think.

Thanks for the reply,

Stephen

Re: Panasonic TX-32LZD80 backlight no picture (fixed)

I think I ended up using a 1.5A fuse

Min order with CPC is £5 now so you may have to add some solder wick or other things to the order.

Thats how i started too, fixed one then thought this could make a good hobby so now pick up free ones from freecycle gumtree etc to practice repairs one. I also done a few laptop repairs now once you get the electronics bug its hard to stop although theres a lot to learn good job for sites like this and google also some good youtube videos on repairs/testing tips etc.

Amazing!!!! I have a degree in Physics but no experience in tv repair at all. Followed your advice and bam, perfectly functioning television. Can't thank you enough. The pictures and website were particularly useful.

I have fixed my first tv and am on cloud 9.
