I have a Hisense 55" Roku TV (55R6040F) that I purchased in Nov of 2020. It uses Roku C205X. Firmware was 10.50.
Everything was working fine until this past Saturday 5/7. This TV is in the basement (we call it Game Room) and we use it for XBOX-X, Nintendo, and regular streaming.
It is connected to the internet via WIFI at a speed of over 600MB-D|41MB-U
I noticed it was on with the "Hisense Roku TV" Blue background and was going off after few seconds and then back on continuously.
I have 2 HDMI and 1 Soundbar using Optical cable to the TV.
I started my investigation and attempted the following sugestions:
- Reset the TV via the button on the back
- Reset the TV by unplugging, waiting 5 min and then plugging the power cable
- Reset the TV by unplugging, waiting 5 min, holding down the Power button and plugging the power cable
- Connecting the TV directly to the outlet
- Disconnecting all the HDMI cables and Optical cable
- Attempting "update.roku" on a usb connected to the back of the TV (that didn't work because it requires additional steps to be takin under System menu)
The only other options I can think of are replacing the motherboard or the capacitors on the motherboard.
I have not exhausted my option yet so those will be the absolute last steps.
I have contacted Hisense Support and they referred me to you by proving me the 816 number and that number said Phone support is not available for my issue!
Looking forward to hearing back from you,
Regards,
