Tv turning its self up?

To Exit Self-check Screen

• Press and Hold Power button on the TV for 5 seconds [or] disconnect the AC cord from wall socket.

TV volume down and OK on the remote only does a basic IC self check. It do not rest the TV. It do not clear channel programmed settings, picture settings, channel labels, lock settings or password. Using this method, it shows the units' firmware version [Peaks 1.050 and GenX 1.00] and it checks the IC communications only. This is more useful to identify the firmware version, without having to decode the info in the setup menu about version/screen.

TO RESET THE UNIT

• To make a reset to TV, turn it ON while pressing the [Volume-ve] button on the main unit, and press the 'Menu' button on the remote control for more than 3 seconds. The self check menu appear on the screen. Then disconnect the AC cord from the wall outlet. [ALL PROGRAMMED PARAMETERS WILL BE ERASED]

i would suspect your control buttons on your front panel on the set have become shorted. specifically the volume buttom down. This is freezing you control functions. like someone is holding the volume down button all the time. or intermitantly. this cuircit board is on front of the set. I have seen this problem a few times at the shop. The common repair is to replace that button assembly cuircit board. I believe the last time it cost the customer around 85 dollars, but like all things depends on the part and the technician that puts it in.

Hello, in many cases, a malfunction of the TV

It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

have u check the menu??? where u can move the audio optons, panasonic has 3 options:
speakers on
speaker off variable pre out (u can connect and amplifier and when u up the volume in ur tv then u turn up the volume in the amplifier)
speaker off continues out (u turn on and down the volumen directly on the amplifier)

try to connect an amplifier to the tv an see if u have sound.

i u dont have sound neither the amplifier the audio in the tv must be damaged.

good luck

unplug and let sit for a min then plug back in

maybe defective speaker or audio output ic or shorted capacitor within audio circuit

Mitsubishi gives this error , when it does not detect a video signal.....Check your wiring.

replace front switches

the tacticle (micro switches)on the front of the main chassis have most likely gotten wet at some time,I suggest replacing them all.
