Re: Panasonic Tx37lzd80

Could you give me a hint as to where the fuse is on the t con panel?

It's just next to the LVDS connector marked 24V/1.6A
A pic of the back of your TV will help.

Re: Panasonic Tx37lzd80

It looks like the fuse is open circuit, what rating is the fuse, is it 1.6ah as marked on the board?

Re: Panasonic Tx37lzd80

The picture uploaded post #6 appears to be the power supply board. Is that where the blown 1.6Amp fuse is or is it on the Tcon board

Re: Panasonic Tx37lzd80

It's on the t con board 24v 1.6ah

Re: Panasonic Tx37lzd80

Go ahead and replace it with a 1.6A fuse. I suspect it's an smd fuse?

Re: Panasonic Tx37lzd80

Some decent pictures would help. I would connect an ammeter momentarily across fuse and check current draw. Use min/max if you have it

Re: Panasonic Tx37lzd80

It's hard to find ppl selling them online, where do you go for yours? I wonder if a wickman fuse would work

[Norman1]

Re: Panasonic Tx37lzd80

Does it matter if the voltage rating is higher

[dick_barton]

Re: Panasonic Tx37lzd80

Hello Norman, without any pictures it would be total guesswork as to what type and size of fuse is on your board. If it's smd is it 603, 805, 1206?
I get my replacement fuses from ebay since they tend to be low value parts and can be sent by ordinary letter post.

Re: Panasonic Tx37lzd80

Don't know if the quality of this pic is good enough to see

I've used them successfully on 5 of these Panasonic TVs now after being recommended by an EE wizard on here. No come backs.

You weren't wrong there.
Measure it as best you can and check against the chart. For example if its a 1206 type then it will measure 3.2mm x 1.6mm.
