Turn On TV and picture is shrunk to "postage stamp size" in upper left corner.

This problem just started. I saw that another subscriber had the exact same problem but there was no solution noted. His question was "Closed".

I have checked ALL the Settings on my Samsung TV.

I spend about 30-45 minutes resetting devices and eventually it returns to Full Screen. Now I have not checked the PIP setting yet. I will do that but this is extremely annoying. The cable box is in the HDMI2 slot.

No matter what setting I try to changes the small view stays the same. Unplugging and replugging eventually fixes the problem...So far.

Problem continues and is very frustrating! No one at Comcast will help! I spend at least an hour and then the problem suddenly clears for just that day. New Samsung tv..IT is NOT the TV!!! Cable boxes new dont solve. THis fix just happened! Unplugged cable box, cable box led flashed dark blue then turned bright light blue..git WELCOME screen, Buenvinedo the voila..full sceen appeared.

Very unbusiness like to treat customers like this. Appears this same issue has been going on for years and Comcast has no idea what the problem is.

When tv turned on only picture shown is in the top left corner of tv screen. After weeks of trying to trouble shoot this problem and Xfinity ignoring repeated calls for hel and stating it was "THE TV" I bought a new tv and it does the EXACT SAME THING!! 👹

I learned that unplugging the cable box and plugging it back in would bring up the Welcome Bienveneido Bienvine screen then after 5 minutes tv picture would be in Full Screen mode.

Today I turned on the tv and a new screen from Xfinity was being displayed. At the top of the Screen, there is a bar that displays Date and time and HDMI 1 then flickers to a 3/4 screen then goes to full screen-normal.

I turned off the tv again and it is now doing this all the time.

I noticed 2 days ago at night when Xfinity access the cable box for information, blue led on side of cable box is flickering on and off.......LED goes very bright, "Source" is showing HDMI1 on the full screen. Prompt on screen sez "Download Complete" and turns off.

Today when turned on screen was at 75% then bar at bottom of tv showed Menu Bar then went to full screen.

I will monitor this and take photos.

Not happy that I had to buy a new TV when one was NOT needed!:mad:

user_0rnt73, Thanks for sharing these details, for monitoring and taking photos. I have been in your shoes before, where I had to troubleshoot on a new TV from Costco, where I kept the receipt so I could return it for a refund. This is definitely not the experience we ever want for anybody. We offer our sincerest apologies for the inconvenience this has caused you. We will certainly do everything within our power to turn this around. Do you have more than one set-top box on the account? Have you tried swapping out the set-top box more than once? As an alternative, did you know that we also offer the XFINITY Stream app on the latest Samsung TV models like in this link here? The Xfinity Stream app offers live broadcast channels, linear cable channels, cloud recordings and video on demand, all without having to rent an Xfinity TV Box from Comcast. I absolutely love being able to use a Roku stick and a Samsung TV with the app for two additional rooms in my home to save money on those rental fees.

Still broken! I was able to take numerous photos of the screen and all that was going on inbetween turning on the TV, the small left corner screen, the unpluggng of the cable box and all that transpired until I got a full screen displayed. There are about 10 Screenshots of the tv and what Comcast was doing until full screen returned.

I will download and post ALL pictures later today, Sunday 02/07/2025

OK   as of Monday 09/08/2025...Problem continued!

I finally got somebody in the Tech Support Dept that knew what they were doing and did NOT blame my TV!

After 2 hours on the "Chat" with LIve Agent...the Tech "Refreshed " my cable box and all is fine as of today.

NOTE: Today when I turned the tv the screen DID go to a small square picture in top left corner BUT it then went to FULL SCREEN.

So anyone else having this problem take note: Have the Live Agent "REFRESH" your cable box!

The Private Messaging DOES NOT WORK!!!!!!!! Live gent walked me through the process and IT DID NOT WORK! The problem is within Xfinity's email system.

So now I have a huge tv that I never needed to buy!

Not HAPPY at ALL!

user_0rnt73, Thanks for reaching back out. We are glad to hear that you got somebody in tech support who was able to help. Are you referring to private messaging with us over our forums page? If so, we never received your name and address that we requested 24 hours ago so we could refresh the cable box on our end. Did you keep the receipt for your TV so you can return it? For future reference, another great way to troubleshoot the TV service and have a refresh sent is to use the XFINITY app, like in this link here.

After 2 hours on the phone with Tech Support...the "Full Screen issue was resolved by the Live Agent "REFRESHing" the cable box!

TV still goes to a 1/4 sized image in the top left corner BUT does go full screen in a few seconds!

Problem has to do with Xfinity's new 4 square PIP function which I do not have nor subscribe to.

Just absolutely TERRIBLE Tech Support!!! My problem continues...I am out $600 for a NEW TV that Xfinity CS said was defective!! WRONG!!!! Problem exists on the NEW tv as well! When I re called Xfinity(Live Agent Chat) again for the 6-th -7th time, I get the exact SAME response..."I will fix it for you now"! WRONG!!!!!!!!!

Initially I asked for a on site Tech to help....2 weeks until a first appointment! What????? Xfinity is so backed up with troubles that I have to wait 2 weeks?

I am a stockholder as well as a customer! This is outrageous!

After todays 2 hour fiasco, a Tier 2 Level agent called and when I told her Xfinity told me my tv was at fault and bought a new one she abruptly said she was confirming my appointment for 09/13...

I had not turned on the tv since yesterday in case the "full screen" mode was still available from yesterday. It was NOT.

I turned on the tv and the picture was only in the top left corner, then moved to middle of tv at 75% of picture size and the image was compressed.

Maxsym and his cousin just left. Pre-diagnosis of CATV signal showed cable box bad.

They replaced box and gave me a new remote and all looks fine...for now.

I will allow catv to run for a day or so and then acknowledge or deny the cable box was defective.

Maksym and his cousin showed up yesterday and replaced the cable box. Pre-diagnosis showed c.b not working properly.

All is fine yesterday and today..

I am concerned that it took about a month to have this done and I spent $600 on a new tv that was NOT the problem.

Xfinity Tech Support has to be more educated on problems.

If  "refreshing" the cable box remotely cured the problem, if even for 24 hours, and I contact them again..that would indicate a problem other than the tv. And when I bought a new tv and the problem still existed.....it had to be external to the tv.

But problem is fixed for now.

Thanks!

Dan

I am having the same issue as we speak.... Every [Edited: "Profanity"] day I have to reset the box because I get the smaller box in the uppwer left corner and the only way to clear it is to reset the box. I tried all kinds of settings on the TV and nothing........ Was it the box??? This is a new box from Xfinity... The old box I had connected to this TV from 2017 NEVER had an issue.   Thanks
