AKAI LCT2721AD remote signal not working

One day my remote control for my tv combo, just stop working. i bought a rca uni control and i didnt work, though it didnt support my tv, went and bought another control and decided to use another tv to test it on and it works. so i am geared to believe that something is wrong with my tv signal.

hi I have the same issue(but with an LCT3201ADC)... Retrohack: Can you provide us some picture on how to dissasemble this tv and where inside is the correct solder point(Did I need to only remove the back panel or did I need to completely dissasemble every part of the tv to acces the solder point?), since I know how to solder, him correct with the solder fix but I never dissasemble an lcd tv and I dont want to mess it up...

This model is notorious for ring cracks in the solder joints on the IR sensor inside the television unit itself. The problem seems to come from pressure being applied to the board during installation. I have repaired three this month! It is a simple fix (just have to reheat the solder joints) if you know how to solder.

If not, the unit will more than likely have to be serviced by a repair tech.

Hope this helps you out.....

By the way, if you are ever in doubt about your remote control itself, use a digital camera to test it ( like the one on a cell phone). If you point the remote at your camera and hit a button on the remote, the infrared signal will show up on your camera screen as visible light. It's a good tester and can save you some $$$!!!

Good luck.....

Try checking to see if the springs for the battery contact have flattened and no longer make contact. Check BOTH the "+" and "-" sides.

I have a AKAI LCT3701AD 37 inch TV don't have the original remote control but bought a universal remote control but is not working Why?

YOU WILL STILL NEED TO PROGRAM THE NEW REMOTE FROM THE MANUAL THAT CAME WITH THE REMOTE. NORMALLY THIER ARE TWO WAYS TO PROGRAM A REMOTE EITHER MANUALLY OR TO DO IT AUTOMATICALLY. YES THE ORIGIONAL REMOTE IS ALREADY SET UP FOR YOUR MODEL OF TV BUT WITH THAT SAID TRY TO PROGRAM IT BY BOTH PARTS OF THE MANUAL. i AM USING A 55 INCH SMART TV AND HAVE DONE THIS AND ON OTHER SMART TV'S. ALSO YOU CAN GO TO THE WEBSITE OF THE REMOTE THAT YOU PURCHASE AND LOOK FOR VIDEOS ON HOW TO SET IT UP. IF YOU NEED MORE HELP LET SOMEONE HERE KNOW. GOOD LUCK.

My AKAI tv/dvd combo - DVD quit working.

Most times it's video read issue such as a dirty lens on the laser.If you smoke in the house or use a fireplace there is a lot of airborn stuff to leave a slight haze on the lens making reading the disk impossible.Try a standard cd or dvd lens cleaner.The on that looks like a cd and uses alcohol on one of the cleaning brushes on the disk you've got a 50 50 chance.

good luck

Akai TV remote is not working correctly

I don't think the Akai remote is designed to work with cable or satellite service. I have to use both remotes & I have Direct TV.

Try unplugging the TV for a few minutes then plug it in and try the remote again. I had the same problem shortly before my Akai LCT2721AD quit working altogether. Three 1000uF capacitors blew in the power supply. Bought 3 new ones and replaced the blown ones myself rather than pay over $100 for a new power supply. Works fine now.

IR sensor problem RCA T25208

You need the proper CODE associated with the Remote.
When doing a set up of the remote, the device (TV I assume) should allow you to put in a code number for that device. It should be listed on the insert manual that came with the hand held remote. Could be in the last few pages.
