AUTOMATICALLY CHANNEL / VOLUME AND MODE CHANGING

Lots of possibilities. If you are using the remote, try also using buttons on the TV to change channels. If TV buttons work, the remote is broken or perhaps try changing batteries and cleaning battery contacts on the remote. If neither work, lots of other things to try. You may need to set preselect channels, so your TV thinks there is only one channel out there until you do. If you are on a cable box you just need channel 3 and change channels on the cable box. I can't tell what you mean by "audio changes with the channel" ... if you mean that when you try to advance channels, it increases volume and moving down in channels lowers volume that would be strange -- if you are using a programable remote it might not be set correctly (try another programming code). The "blurred" picture is probably symptomatic of having the set on the wrong channel, and if you could set channel it might clear up ... I'd start with getting channels to change. If you need more help, give the brand and model of TV, say if you are using a remote (original or programable), and what the 'audio changes' comment means in more detail. Probably worst case is that your tuner circuit is fried, but don't assume that without more diagnostic.

Tries tv unplug,replug it back like about an hour.The tv now,will be resetting itself back to the factory setting.The tv now,should be working right again.Not, if it have the same problems,than the tv Tuner signal board have internal shorting problems.That the board,where the incomming broadcasting signal cable plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

On your remote control (with tv off)
1. press Display, channel 5, Volume Up and then Power
this brings up the service mode (you will see some green text on your screen)
2. Press channel 2 to scroll through options until you see "Micro" in the upper left of your screen
(channel 2 cycles up through the options, channel 5 cycles down)
3. Press channel 1 to scroll through suboptions until you see "DIOF" appear under "Micro"
(channel 1 cycles up through the suboptions, channel 4 cycles down)
4. Press channel six until the default value (12:60) changes to 12:40
(channel 3 increases the value, channel 6 decreases the value)
5. Once the value has been changed to 12:40, press Muting and you should see red text in the upper right hand corner that says "Write"
6. Simply turn the power off and back on for the change to take effect. Your volume problems should now be fixed.

Keeps changing channel
Check voltage on D12 if below 4.8V then change
Changes channel or volume adjusts by itself
Check S900/1/2 on pcb H1, alternatively this could be due to failure of IC005 (CD4052BCM-FL63) on pcb A
