Remote control vs tv led

It would appear that the remote control does not work since the tv will power on and function manually. However, after several univeral remotes it seems that the problem lies within the little led screen on the tv that receives the signal from the remote....now where do I go from here to repair it?

On the little PC board which has the pushbuttons on it, mounted right behind the buttons on the front of the TV, is the remote (IR) receiver. It is a little black box with 3 leads soldered to that board. One pin is grounded, one pin is +5 volts and the third is signal. The signal pin should be a little less than 5 volts, and when you use ANY remote the signal pin should have inverted digital data (about 4.5 to 0). If you measure the signal pin and it is near zero volts, replace the receiver. If the signal pin is around 4.5 volts, replace the remote.

Philips 19PS50S122 TV does not respond to remote control

Hello,
Please check your batteries in the tv remote as they appear to be weak or dead. You will need to find the cable remote's paper guide in order to properly program the cable remote so it can change channels, volume, and power functions on the tv set.
Good Luck!

I need a code for a memorex dvd

Your code is not listed on the manual . Try searching for the code. Here is how: (P.S. if the search function does not work you may have to try a different brand of universal remote.) SEARCHING FOR YOUR CODE If your device does not respond to the remote control after trying all codes listed for your brand, or if your brand is not listed at all, try searching for your code. NOTE: Before performing a code search for a DVD player or a VCR, turn on the device and insert the required media. For example, to search for a code for your TV: 1. On the remote control, press TV once. 2. Press and hold SET until the LED (red light) blinks twice, then release SET. 3. Enter 9 - 9 - 1.The LED will blink twice. 4. Aim the remote control at the TV and slowly alternate between pressing POWER and TV. Stop when the TV turns off (after pressing POWER). If the device does not have a Power key, you can substitute another function, such as digits 0 ~ 9 , CH, or PLAY). NOTE: In the search mode, the remote control will send IR codes from its library to the selected device, starting with the most popular code first. 5. To lock in the code, press and release SET.The LED will blink twice. 6. To search for the codes of your other devices, repeat steps 1 through 5, but substitute the appropriate device key for the device you are searching for. here is the manual for your remote:

I need step by step instructions to program the codes into my One For All universal remote URC-4220 to my JVC tv.

The code for a JVC TV is 0053 (non-combination TV). To program the remote, turn on the tv manually. Then press the TV button once. Then press and hold Set until the LED blinks twice. Then release Set. Aim the remote at the TV and enter the four digit code. The LED should blink twice again. Press the power button on the remote. The TV should turn off. Turn it back on and check if the remote does the other functions that it should for the TV.

There is a manual code search option. Press TV once, then press and hold Set until the LED blinks twice. Release Set and enter 9 - 9 - 1 . Then aim the remote at the TV and alternate between pressing Power and TV. When the TV turns off, press Set to save the code. Turn the TV back on and check if the remote performs other functions. If not, repeat the above steps until another code turns off the TV.

The manuals for All-for-One Remotes are available here: http://www.oneforall.com/support/manual . Choose universal remote control in the top drop down and then the URC-4220 in the second.

Please note that universal remotes only have codes for devices released 6 months of more before the remote was programmed. If your TV is newer than your TV, then you may need a newer remote.

I hope this helps.

Have to manually turn on tv when turning on digital converter box

astoner3,

Our dish remotes are compatible with most TV manufacturers. On some older TV, we may not have codes that allow for full functionality for the DISH remote. I have provided the most common codes to work with the Sharp TV. The codes are: 628, 605, 740, 591, and 606. I have also provided instructions on programming the remote to the TV.

Remotes: Basic (Television Only)
  1. Turn the Television On
  2. Press and Hold the TV Power button for three seconds until the LED flashes
  3. Enter the three-digit code using the buttons on the number pad.
  4. Press OK. Note: The LED will flash three times.
  5. Test functionality with the TV
  6. Return to Step 2 if the remote is not able to turn the TV On/Off, change the volume and mute the television.
