After switching unit off for two months while derorating, put tuner back into use and it keeps switching on and off intermitantly. tuner was put into cold bedroom while off - any ideas

Probably have some bad Capacitors in the Unit, they degrade with age pretty badly.

Break the connection and power everything off for at least 10 minutes. Take the sub out of the room. Turn on the tuner and give it a few minutes to come "up to operating temp" (let it run for a bit).
After a while, turn the tuner off for another 10 min. Bring the sub back in; turn in the tuner, let it run a bit, re-establish the handshake between the woofer and tuner. That should take care of it. If it doesn't, one of the units (probably the sub) is in need of repair or replacement. Just because it's only a couple of months old doesn't mean anything any longer.

I had this exact same problem - in my case caused by the wire that should provide a continuous feed so the unit can keep its settings actually being from the ignition switch, and the continuous feed wire being connected to the terminal that should be from the ignition switch! I had a red wire (continuous feed) and a yellow wire (ignition activated feed) feeding to the back of the unit, and all I did was to switch these over - both wires had their own connectors let into the wires a few inches from the unit so that switch over job was easy. Works as it should now, although i have a grazed knuckle as the wires leading to the plug at the back were a bit too short! Chris

The tv Tuner signal board it is the causes and problems.Because ur tv are intermitently shutdown after an hour of used.Mean the tv Tuner sisgnal board have some kind short in it circuitries,could be anythings,components parts wise.The tv Tuner signal board,that the board where the incomming broadcasting signal cable plug into it.U have some skills,like u can take things aparts and putting it back together again?Yes,tries websites like Shopjimmy.com,Ebay.com to buy a tv Tuner signal board for the replacement.

Do you find water in the bottom of the unit?

Here are some things you can try.

Keep it off the floor a few inches. Use foam or wood blocks or strips.

Keep the inside dry. If ice forms on the cooling unit, it will stop the fan. If this happens, you can defrost it by unplugging it for a short time. Dry the inside good.

Keep the outside fan and heat sink clean. Use the "canned air" and blow off the fan and heat sink.

You can take off the fan covers and remove the fan units ( use care the fans ar easy to damage) Pull the stickers off the back a put a drop of very light lube. Put it all back together and should work.

When you get tired of doing this every month, or the unit fails. Go by a koolatron unit. Better unit, less trouble. Only one moving part. And if it need replacemnt, most truck stops have them.

Hi

Hi
Good Luck
The 6A00 is a Canon generic code for paper path jam.

Solution 1:
Move the printhead carriage back and forth a few times.

Solution 2:
Check the purge unit: Moving the print head assembly will not clear a purge unit if its jammed with paper, paper clips, push pins, screws, cookie crisp, flower bud pods or the like.

Solution 3:
Press the ink pads down in the purge unit.
Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
