Question about Sony 42XBR900 Television

Open Question

Possessed periodically, the tv volume will automatically either go all the way up, or all the way down. during this time, the tv cannot be controlled with the remote or manually off the buttons on the tv. the power switch doesnt work either when this happens. this will go on for several days, then just like it started, it'll go back to being a normal tv again.

The problem is your cable box. I know you said you replaced it, but I work on TV's everyday and, sorry to say this but cable box HDMI outputs have serious issues, like no or intermittent sound and video. I have seen customers exchange their cable boxes 5 and 6 times and still have the problem. Your best bet is to use the component outputs of your cable box, visually you will not see a picture difference between component and HDMI when using a cable box. Your other solution is to get satellite; I have NEVER seen an HDMI issue with a satellite box

Volume automatically goes to maximum on TCL TV

The volume (+) button on the TV is stuck or soiled if the volume automatically increases when the TV is turned on. To find out:
  1. Turn off the TV.
  2. Press and hold the volume (-) button on the TV then turn it on.
  3. If the volume doesn't automatically increase, you have a stuck button.
  4. If it does increase, you have a faulty key control board.
  5. In either case, you have to replace the key control board.
To find it out further:
Warning: Beware of electric shock.Please do not proceed if you do not have the skill to do the following.
  1. Unplug the TV.
  2. Let it stand for 15 minutes to allow voltages to drain completely to avoid the risk of electric shock.
  3. Remove the screws securing the TV's back cover and pull it off.
  4. Disconnect the cable that runs from the main board to the control key board.
  5. Turn the TV on using the remote.
  6. In this manner you can use the remote control to run the TV while waiting for the control key replacement board.
To do a hard reset of the TV, unplug it and let it sit for 2 hours or long enough to completely drain the internal voltages.
