My problems with this tv started with a black screen which I posted:

I replaced two bad caps and jerry-rigged a replacement for a blown surface mounted fuse for which I could find no replacement. The repair was successful - for about 3 hours I had picture and sound. Turned on the tv after that and had picture but no sound. I can find no visual evidence of electronic failure. I do not have a service manual. I have built stereo kits in prehistory but no background beyond that in electronics....

I have learned that the fuse is a smf, surface mounted fuse. I am sure that some of you knew that. I did not. Despite the new-found intelligence I was not able to find a replacement for it anywhere.

So, what I did was go to RS and buy 2.5A, 250v glass fuses, jerry-rigged a fuse holder out of scrap brass sheet with leads soldered to the contacts on the board of the smf. I taped up the whole mess to insulate it, carefully laid it on top of the board, re-assembled the case, plugged it in, attached the cable box, waited...

Here's the photo. Hard to make sharp with such tight close-up. It is the chip at the F1 box. It measure 1/6" x 1/8." I looked a little on line and cannot find anything that looks that small. I don't even have the complete specs for it or what, exactly, to call it.

I hope that helps. Thanks.

I am not sure how to move this thread if that is needed....

So, I got the caps and installed them. Still no video. Before getting back to my post, I found this:

There is talk of a 2.5 A fuse located on the bottom of the board where the flat cable is attached. I find a tiny red thingy, 2.5A stamped on it (needed a magnifying glass. I grew up in the 50s -60s and did not need tweezers nor magnifying glasses to work on the hi-fi kits I assembled.). I put a meter across the contacts...

There is an external power supply. I have ordered new caps, from elsewhere before I knew of this site.

I am trying to make sure that the caps did not fail due to a fault elsewhere that will destroy the new replaced caps. I am trying to understand why two caps would fail together without some exterior cause. Unless the they shared some kind of load that, when one failed, the other was over taxed??

The sound works, but the case enclosing the panel is cold not warm like when the tv was working.

As someone who hates to throw things away I looked to see if anything could be fixed. See photos of two caps with bulging tops. My worry is that they failed from some other fault elsewhere. I am wondering if anyone can point me in the right direction. Before I came here someone suggested the inverter... Ultimate problem is a new tv of this size is available at ~$150

TIA
