Shortly thereafter, I put a USB in the front port......16GB at first, but not a long one, and have since replaced that with a 64GB low profile.......and have not had one picture freeze on any discs I have watched. I have not watched any of the original discs that froze, but I assume the problem is solved. I believe I read about this suggestion somewhere on this forum.
Try a USB and see if it helps.......incidentally, my player is not connected to the internet and I only use it for UHD discs.....
You don't need to use an unsightly USB sticking out of the front of the player to solve the "freezing/lock up" problem; This is the cure for the "freezing problem".
A while back, someone posted a link to an article that detailed the issue/problem and the solution.
The gist of the article was this: the lazer and error correction software on many new 4K UHD players (it appears SONY players seem especially susceptible) is literally "seeing/reading" the INVISIBLE "non stick" film that coats EVERY UHD 4K, AND Blu-ray disk that is applied during the manufacturing process that is intended to keep the disks from sticking to each other while they are stacked on top of each other before they are individually packaged for sale, and is trying to "correct these 'errors' as the disk is playing."
Consequently, the UHD 4K players ability to keep up with correcting the supposed "errors" on the 4K UHD, or Blu-ray disk eventually fails and causes the player to "freeze"/lock up.
Older, non UHD Blu-ray players don't appear to have this problem because they don't "see" this invisible film.
The simple solution is this: *Note this procedure must be done to brand new 4K disks, as well as all of the HD and 4K UHD disks in your library BEFORE you play them the FIRST TIME on your 4K UHD player.
Carefully remove the disk from its case, and place the disk under under running warm water.
Lightly coat the disk with mild dish washing liquid (I use Dawn) on BOTH SIDES and wash the disk under warm running water (I lightly rub the soap from the center outwards).
Turn the disk over and repeat.
Thoroughly rinse the entire disk on both sides, making sure the dishwashing liquid is completely removed.
Place the washed and rinsed disk between a soft towel and pat dry. *Note: As an additional step, I take the dry disk, carefully hold it between my fingers and lightly move it up and down to remove any possible residual water.
Place the washed and dried disk in the player and push "Play".
Because the invisible (to the naked eye) film has been washed away, the player no longer "sees/reads" it as an "error" and the "error correction" protection software no longer gags and freezes after it can't keep up with the innumerable number of perceived errors.
I have religiously followed this procedure BEFORE playing any new or existing 4K, UHD or Blu-ray in my library for the FIRST TIME.
Since following this above process I have only had one disk freeze/lock up my SONY X1000ES. After rewashing the disk, there was no longer a problem and the disk has played flawlessly ever since.
*Note: You only need to thoroughly wash each disk ONCE/ONE TIME, BEFORE you play it for the FIRST TIME because you have permanently removed the invisible, non-stick coating that was left on the disk during the manufacturing process to keep it from sticking to other disks.
I hope the above advice proves helpful; it has certainly worked for us and now our SONY X1000ES plays everything we put in it without a problem
