Cant change from av to any input


First try a simple "reset":

1) Turn TV off. Unplug all TV inputs, and the AC plug from wall. Wait 5 minutes (I mean it, a full 5 minutes!).
2) Connect your normal TV source (cable or satellite) ONLY, then plug in and turn on the TV.
3) You may need to press the RESET key twice after connecting the signal and turning on the DTV to restore some functionality.

Now plug in ONE A/V component at a time to test. You can also try replacing any A/V cables (RCA red/yellow/white, HDMI, etc.), as cables do occasionally go bad.

Make sure TV is "tuned" to channel 3 before pressing the "input" button on remote control This is easiest done with the actual channel up/down buttons on the front of the television itself, or possibly by pressing 03 (or 03, Enter) on the remote control.

You may find that only one A/V input is bad (ex, VIDEO 1 port), while others work.. or they may all be bad.

If other functions of remote control are working (but "input" button still does nothing), could simply be a bad remote. Try eBay for a cheap replacement.

If there is not a manual "input" button on the TV itself (I think not for this particular model), and you still can't change AV input, you are probably out of luck. I recommend read included instruction manual carefully, then contact the manufacturer if needed. Instruction manual may be viewed at:
http://www.manualslib.com/manual/599522/Sanyo-Dp42746.html#manual

Do not attempt to disassemble TV. There are no user-serviceable parts inside, and even an unplugged TV can retain enough electricity (in capacitors, etc.) to seriously hurt a non-trained human. This TV is probably ~ 9 years old; parts are available (eBay, etc), but may not be worth fixing considering huge price drops on new TVs available now.

I have a 32" RCA LCD tv , rlc3210 power input says


Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

Can't get my westinghouse tv to recognize dish network


Happy to help get that fixed right away!

You mentioned that your TV is not recognizing the DISH Network signal, since wedo not know how many TV's your receiver is able to support, or whether it's theTV1 or TV2 having the issue I will address them both.

The first thing we want to do is ensure that all connected components arepowered on (VCR, DVD Player, etc.). Check what channel or input your TV iscurrently on by powering the TV off then back on and noting the channel orinput that appears on screen when the TV is powered on.

If TV1:

Check what type of cable is used to connect the TV to the receiver. If you areusing a Coax Cable to connect the receiver to TV1, check the receiver'sback panel for the output name. If your receiver has a "TV CH 3/4Out" (non-ViP Receiver): Tune TV to channel 3 or channel 4,if it has "Home Distribution" output (ViP Receiver): Tune TVto channel 62 or 75. If using non-Coax (RCA, Component, orHDMI) to connect receiver to TV1, cycle through the inputs until pictureappears; most TVs have a "TV/Video", "Input", or"Source" button. If the issue persists, check that theconnections between your DISH receiver and your TV are secure then reset thereceiver by unplugging it from the outlet for 10 seconds then plugging it backin. If not fixed then connect another component (VCR, DVD Player, etc.) to thesame TV, using same cable, same input, and same channel to see if it works. Ifit works with the other component then call us at 1-800-333-DISH (3474) foradditional troubleshooting, if it still doesn't work with the other componentthen the cable should be replaced.

If TV2:

Access "Modulator Setup" from TV1 by pressing the menu button(on the top left of DISH remote) then pressing the numbers 6-1-5. Tune TV2 tothe channel that appears under "TV2 Out" on screen. If stillno picture, verify the mode (air or cable) that TV2 is on. Then change themodulator setup to match this mode (air or cable). After changing modulatorsetup, tune TV2 to the channel that appears under "TV2 Out" onscreen. Check that the connections between your DISH receiver and your TV aresecure then reset the receiver by unplugging it from the outlet for 10 secondsthen plugging it back in. If not fixed then connect another component (VCR, DVDPlayer, etc.) to the same TV, using same cable, same input, and same channel tosee if it works. If it works with the other component then call us at1-800-333-DISH (3474) for additional troubleshooting, if it still doesn't workwith the other component then the cable should be replaced.

TV Stuck on 1 channel


We would be happy to help get that fixed right away. The first thing we want to ensure is that all connected equipment is on. We want to then check what type of cable was used to connect the TV to the receiver. If you are using a Coax Cable to connect the receiver to TV1, check the receiver's back panel for the output name. If your receiver has a "TV CH 3/4 out": Tune TV to channel 3 or channel 4, back if it is labeled "Home Distribution": Tune TV to channel 62 or 75. If using non-Coax (RCA, Component, or HDMI) to connect receiver to TV1, cycle through the inputs until picture appears; Most TVs have a "TV/Video", "Input", or "Source" button. If we are still not getting a picture then unplug receiver for 10 seconds then plug it back in, this will reset the receiver, then try cycling the inputs again.


We hope these steps resolve the issue. We want to thank you for being a valued DISH Network customer!

Tune the tv to a channel that is just blue screen. Then turn the tv off and unplug for at least 30 sec. Then plug the tv back in and turn it on. Then leave the tv on the blank screen channel go into the menu and do auto cable channel search. After the search is complete try all channels. This worked for me. My tv will not scan if the tv is on a channel that comes in. GOOD LUCK these tv's are junk .

TV does not recieve a remote


Hey, Have you tried to power cycle your remote? That may work, do the TV too. I'll give ya the steps, just follow them and you should be ok. I'll throw in a factory reset as well, but if you're not using a cable box you will have to run another auto scan. anyways start off by unplugging the TV and removing the batteries from the remote control. Let them both sit, you don't have to let the remote sit really, but I do for good measure. You have to let the TV sit for a minimum of 5 minutes. at the end of 5 minutes, you have to find the physical power button on the TV, this means NOT on the remote, but on the TV itself, you have to find this power button, and you have to hold it down for 1 solid minute. Again, any time you can do something extra for good measure, it can't hurt, so if you want to leave it unplugged for 10 minutes and hold the button for 2, go for it, it may help. After you're done with that, power cycle the remote control. Being that your remote seems to be haywire, go ahead and press every single button, this means channel up and down, even if they're on the same button, every one from the top to the bottom, 5 times with no batteries in it. Then hold down the power button on the remote for 30 seconds. Then replace the batteries, preferrably with new ones. This completes the power cycles for both the Remote control and the TV. Now, before plugging the TV back in, we have to do the factory reset. Again, hold the power button on the actual TV, and then, while holding down the power button, plug in the power cord, wait for a couple of seconds, and then release the power button. Wait for a moment, and then turn the TV on. This completes the factory reset.

The reason for all of this, is, power cycle the remote to drain it's capacitors and reset it, power cycle the TV incase the Remote sensor is affected by a static electricity build up. Factory reset incase any settings may have caused this. Hope this helps.
