Re: Remote sensor in the TV

First Inspect the remote batteries. also make sure TV is not on a LOCK ON option... now, the sensor is a small smoothly part near the TV front buttons, you can clean it carefully FYI, exposing unit remote sensor to direct fluorescent or outdoor light may cause signal interference.

Since it works when close, more likely the battery in the remote is running low, or you have some dust over the remote sensor on the front of the tv panel.

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.

My Mitsubishi projection TV will not produce audio or video


Hi,
Two things are involved to cause that problem, tv remote control and remote sensor in tv.
Upon verification of remote working, it would be confirm that remote sensor in tv is defective and need to be replaced.
Remote control sends infra red light signal to tv and we can not see that light with naked-eye, so need digital camera or cell phone camera to see it by watching remote front through camera, press any keys on remote, if you see infra red light is blinking in remote front that means remote is working and remote sensor in tv will be replaced.
If no light blinking on pressing remote buttons confirm that this remote is defective and buy new remote.
Let me know if you have additional question.
Thanks.

The remote operates all the units except for the TV's vol, channe


There are 2 possibilities: either you have a stuck front panel button, or the remote sensor is bad.

You can eliminate the button issue by removing the front speaker grill and access panel and disconnecting the button assy wiring harness.

There is a plug/socket connection there that you can easily disconnect. If after disconnecting the control panel, you still have no remote, its the sensor. Its located behind the screen assy mounted behind the CRTs. You will have to remove the screen assy to get to this.

If you're not up for this, a service company will charge you $300 or so to replace the sensor for you.

Tv turns on manually, but auto flips through channels and you can't use remote


Found this in another forum (www.hometheaterspot.com) and it fixed my remote problem:

"...it's possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."

You will need to get to the control board and see if any of the front panel buttons are sticking. if they are not, you will have a bad switch or the remote sensor is defective. If you have no TV repair experience. you will need to consult a pro to assist you with this repair. Good Luck
