SOURCE: Auto Channel Search places all channels in Skip

check the agc line from the tuner is functioning properly, if the agc signal , is not reaching the processor it will register that channel as being inactive and lock it out, there is not much circuit to contend with so a multimeter should do the trick to trace down the fault, you should find AGC marked on the board where the tuner modual is mounted.. i suggest obtaining a service manual to do the job good luck

Panasonic in lock mode and unable to unlock picture


Panasonic sets need to be reset to clear the v-chip settings. To do this, put it in standby mode, then press the POWER and ACTION buttons at the same time and then turn the power off. The set should reset to the factory defaults, and reset the v-chip. If you can't succeed, you must enter its service mode menu to make an unlock. Visit the site named 'Electro-help'. Click this link. Do a search by entering the brand name to your device by its search box at top right of the display window, because, posts are not arranged in alphabetical order, but by brand name at first.

Auto Channel Search places all channels in skip mode causing channel changes to made by number input instead of up/down button. Having to manually turn "Skip" off on each channel individually.

I cannot get my Olevia 226 T11 to do an auto search for channels. I've tried to do this per the manual. The auto channel screen just locks up.


Check the Power Up setting to be sure it is starting up in HOME mode rather than SHOWROOM mode. In showroom mode, many settings cannot be changed.

Impossible to change channels, turn TV on, Power and Opc blinking


go into programming mode and search for channels   it will do this automatically to find all antennae and all cable channels    if this is hooked up to a receiver box then only channel 3 will be found or used    also most tvs are computerized these days and at times it will need to 'rebooted'     unplug the power and wait 10 seconds and plug it in again    this may have to be done whenever you are locked out from changing channels or using the volume controls

I am unable to connect to my VPN, although my wireless connection is excellent


Double check that you are using the proper WEP key and VPN settings. You can also try using a different channel for your wireless. Many of these systems use Channel 6 as the default channel. Change this to channel 10 in the router. If you are forcing 105mbs you will need to change that to automatic to make this change as in forced 105 mode the only broadcast channel to use if 6.
