I have a Sony KDF-55WF655. I think the IR sensor is going bad. My remote occasionally stops working for no reason. I have tried numerous different remotes, but I get the same problem no matter which...


Hi:
The IR receiver inside the television is becoming intermittent and needs to be replaced. You might also check the connections on the receiver small circuit board for cold or loose solder joints.

Yes, most likely the sensor is at fault - more precisely it's connections to the motherboard are iffy. You must take the back cover off the tv and reseat them. While you are there check their soldering points - with age they tend to melt and get loose.

No remote control will work the tv anymore. Could


Hi I am Vortash , Its possible the IR detector has gone but unlikely , it is more likely that due to a low battery in a remote the signals have corrupted the remote processor this used to happen a lot with the old EMI and Bush sets and sometimes it is just a fact that the remote has given up the ghost . You can check to see if your remote is working with your Iphone or any phone camera . Put the phone on record and place the remote in front of the lens , if it is working you should be able to see the infrared diode flashing in the phones viewscreen . If it is working you will need to find out the de- corruption proceadure for your model of set hope this helps regards Vortash

The remote for my Panasonic HT520 doesn't respond. When the CD-DVD button on the remote is pressed the lights come on on the remote, but still nothing from the player. The player works fine on it's own,...


Ok let me verify; you have an HT-520 home theatre with integrated DVD player. When you press the DVD input you can't control certain aspects of the DVD player or the DVD player does not respond at all?

Does the DVD respond at all if you put the remote into another mode (should be called Amp or Receiver)? Can your remote be programmed for different devices and mabe it was programmed to control a different DVD player?

I will search the unit in my knowledge base and let you know some exact steps to try. If you could clarify some of thoes details that would be wonderful.

Thanks,

Kevin

I've got a samsung le32m8 tv. the remote is not working light flickers on remote and tv but nothing happens. the power button is the only one working


You should try another remote to determine if the remote is actually defective, or there is a fault in the TV set. I have seen both scenarios, of either the TV was defective, or the remote was defective.

I suspect the remote to be defective more than the TV having a problem. The reason is that you can use the remote to turn the power on and off in the first place. This means that in the TV the IR receiver module, and the remote circuit processing to the uPC is responding.

If it is not the remote that is defective and the TV's IR path is responding, there are several other possibilities. There may be lockout function in the user menu that locks out the main controls from the remote. There may be some other type of defect with the uPC system controller. This can be firmware, or some type of hardware failure which would be a bad device in this area on the circuit board.

There are control circuits for the functions in your set. In most TV sets they are shared with the front panel controls. There could be a fault in this area as well.

Anything past trying another remote to verify the remote functionality of the TV, and checking the user menu for a lockout feature, will indicate that there will be the requirement for technical service.

TV does not respond to the remote control


I had this happen on mine after about 3 years. Luckily it was on extended warranty. At first the techs re-soldered the connections to the board for the IR sensor but the problem was still intermittent. The next time they replaced the mainboard and all is well - just like new.
