Here are a few suggestions to help you with this problem:
It is possible that the battery contacts are corroded so you might try expecting the contacts and cleaning them. Since you cannot see if the IR signal is being sent, you can use another IR remote that you know works and see if you can Jam the signal of the working remote with your Hql-260wr remote. To do this, push the volume up button on the TV remote and hold it down while at the same time using the known working remote to control its companion product. If the working unit stops responding correctly when the volume button is pressed, it is transmitting an IR signal.
In this case, since you confirmed that the remote is transmitting, you can make sure that you are on the correct device settings for the remote. If you select the TV setting for instance, see if the remote now can control the TV. The main functions to try first are volume and channel buttons.
If this does not work, you will need to find out where the IR receiver is on the TV and make sure that the receiver lens is not blocked by something such as another device like a video console, etc.
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!!
Hey there, Cheri Torres with DISH Network Customer Service here. It sounds like you are going to need to change your TV back to the proper input or channel. If the TV remote is not working to change the channels you can also use the buttons on the front of the TV. First look for a button listed as either input, TV/video, source or AUX. When you press this button it will start cycling through all the inputs available, make sure to cycle through them slowly because it make take a couple seconds for the picture to come in. If you do not find a picture on any of the inputs you are going to need to try the different channels. Normally for a TV where the receiver box is the TV should be set to channel 3 or 4. Once you have found your DISH Network picture you will want to make sure to push the SAT button on the DISH remote so that it doesn't change the TV channel again. I hope you find this information useful and if you have any further questions or concerns please let me know. Thanks. :)
