SOURCE: I have 42 in ilo plasma tv. I can turn tv on but

Most likely the TV has a Mother board related issue. Your TV is just like a computer. When it freezes up, nothing responds and you have to pull the plug to turn it off.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part or replace the whole circuit board. The Service Manual will give you circuit diagrams, test points, and part# lists.Service manual cost about under $20. Most cases the new part cost less than $15. New circiut board, depending on type, may cost about $125.

I hope I shed some light on the subject for you.

SOURCE: 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

Bush lcd42f1080p100hz remote will not turn tv on


I had come home about a week ago and pushed the power button from my remote but my tv did not respond. So I just went to the front panel and pushed power but once the tv turned on, the volume was on full blast! I used the front panel volume decrease to get the volume down, but when I stopped pushing the button, the tv increased its volume to full blast again by itself! Naturally I just turned the tv off for a few moments. I tried the remote again, no response again, so I used the panel power button. The tv volume was still full blast when it turned on but after I decreased the volume it stayed this time. The picture is and has been perfectly fine and the tv was working fine. The next day the problem started all over and now once we turned it off from frustration of having to manually use the panel to change channels, it now will not turn on at all. I have changed batteries from my remote, reprogrammed my remote, pushed system reset several times, unplugged it for a while, bought a new surge charge, and even held the menu and device panel buttons for 10 sec and tried to turn the t.v. on again! What other options do I have or what may be the issue at hand and possible parts that may need to be replaced?? Thanks!!

I have Aiwa TV MODEL No. TV-A219 The problem that I am suddenly facing is that I can't change channels or volume or use any other function. I can't even turn it off with remote control. Its


Hello
Check your remote control hanset for proper functioning. Get into this link to know more about the faults and repair to remote contorls.
http://www.fixya.com/support/r10192276-cleaning_remote_control_handsets

If remote control functions proeerly, the front panesl switches to be suspected. If any one mong the microswitches inside got strucked, all functions will be distrubed. it will be best to follow any more after replacing these microswitches. These switches can be located just behind the control panel of the tv, soldered diretly to a printed circuit board. You have to replace all of the at the same time. Just undolder one amoung them as as sample, when you go to buy for a new one.
If this also does not help you, repalce its memory IC. This IC can be located very near to the main system control IC, will have 8 solder terminals. A very small IC and wont cost more. Eventhough it is very small, function of it when the set works is great. Replace it. When you buy this IC, make a keen look on it number. It is very important when replacing this IC. All these components stated above, can be bought from most of the electronic spare part selling shops st your town. OK.

Wotcha, i've just taken amp out of storage, has'nt been used for a while cant get volume to work properly the sound goes from speaker to speaker and up and down in volume whilst crackeling a lot as...


One way of proving it ISN'T the amp circuitry is to remove the pre-main jumpers and jack in a source that has its own volume control (or try a CD that starts really low) because this bypasses ALL the amps controls. If it sounds ok (albeit LOUD) I'd suspect oxidized contacts on the controls. Turn it off and vigorously operate all controls a zillion times to wear through it. In mosty cases it's the unused controls that fail because they never get wiped. Maybe a shot of contact cleaner on those you can access.

Go to your menu and choose picture. See if your settings are normal or if the brightness is turned down. If it isn't then it's a problem with the T.V.

have Aiwa TV MODEL No. TV-A209
The problem that I am suddenly facing is that I can't change channels or volume or use any other function. I can't even turn it off with remote control.

Its stuck randomly on a particular channel that I was watching at that point of time.

Along with that channel it now shows a message in flashing red color that reads :-
AGING
O6895H

Now when I press ''Display'' button on remote control volume goes off and this code is shown :-
S123 K234 Y
000 001 1


The numbers in the second line can be navigated by ''CH+'' button and changed between 0 and 1 by ''Vol+'' button.

I really don't know anything about this. So, please help me out of this problem.

and on the right the value of the parameter V00
5) release buttons.
