I assume it DID work at one time. You need to take it apart and see how the tray is driven... belt or gear. If belt driven you could replace the belt.

Disassemble or open the remote control Sony RM-YD035

if Sony Remote RM-YD035 does not change channels or turn off TV, the buttons got dirty coz those are you most used buttons.

You can repair Sony Remote RM-YD035 yourself. It's quite easy and fast, with perfect result!

To disassemble or open the remote control Sony RM-YD035, first remove a single screw in the battery compartment. Then use a very thin but strong screwdriver and insert it between top cover and the body at the back part of the battery compartment. Move the screwdriver up and down and slowly move it to the left and to the right and continue along the perimeter. Use two or three such screwdrivers and in 2-4 minutes the top cover plate with buttons will separate from the body/bottom/casing.

Clean both parts thoroughly. And then gently put them back together in the opposite order. The parts will snap closing.

You are done.

Mine is now working perfectly

Fix your dodgy remote buttons

Hi.This is a guide to repair dodgy remote control buttons. This procedure is about sorting out dodgy buttons. If you remote does not go at all, they following may not help I will work several times generally, although some silicon/carbon contacts can become RS This procedure also works if you have a remote with coffee, coke, or other beverage spilt on it

You will need

  1. A med or thin guitar plectrum(pic)
  2. Methylated spirits
  3. Lint free cloth(tea towel will do).

Now I will take you through opening and cleaning the remote keypad.

  1. Remove clip on cover and batteries
  2. Slip the guitar pic under the edge of the remote.
  3. Run it around whilst gently levering the cases apart
  4. It will open with some patient effort and then pretty much fall to pieces

If the remote HAS HAD A DRINK..... wash all parts in warm mildly soapy(dishwash in kitchen sink). DRY PCB IN THE SUN, or on TOP OF A TABLE LAMP.
Dont dry the plastic casings this way... they can melt!! Just leave them in the open air
  1. Clean the pcb/contact board by gently wiping with the cloth moistened with metho
  2. Clean the silicon rubber button contact pads.
  3. Be sure that no bits of lint or residue are left on either the pcb or the contact rubbers.
  4. Let dry for 15 mins to be sure no condensate moisture or metho is left on boards or button assly
  5. Reassemble by layering parts and clip together
  6. check that terminals are not corroded. Use an emery nail file to buff them up if there is corrosion. Spray contacts with CRC2-26 or WD40
  7. Reinsert batteries(fresh ones) and test on appliance. You can also see a remotes Infrared LED flashing when it is working by viewing it with a a phone camera, or camcorder

This process will cure most dodgy button problems. If they are still not good, try the process again.... or a new rubber contact sheet may need to be fitted. In the case of universal remotes, cost will probably dictate buying a new one anyway.Good luck and go FixYa!!

If your remote still has problems there are yet other cures. I will post more as time allows. ;)

When pushing the channel down or channel up turns four our five channels up or down. Ie. not one at a time....what's up???

Your remote control need to be cleaned. I've given its proceedigns about how to do it, in my Tips. I'll copy and paste it for you here.

Remote control handsets of most of the electronic devices will get damaged after some time. Some of them can be set right by cleaning the remote control. Remote handsets of some devices will be not available to get from the open market or even from the service centers of the producers. In such cases, cleaning tme may get it to work.

Normally, all infrared type remote controls are made up of silicon rubber touch pads. Each touch button in it will have a small carbon button inside it, which comes in contact with the carbon track on the internal circuit board. These carbon tracks are connected ot various pins of an IC [Integrated Circuit] on the remote's circuit board. For each button touch, generates signals of different frequency, which in turn activates the infrared LED [Light Emitting Diode], which emits infrared light waves of the same frequency. This infrared light waves are recived at the device to which controlled[whether it is a TV, DVD, VCR, DVR etc:]. There is an infrared reciever inside the device, usually called "remote sensor", which receives this signals, convert it to corresponding frequecny signals , and processed by the main system control IC insid the device and contols it.

Generally, the remote handset can be called a neglected device. No extra care will be given to it by the customer. The batteris in the remote control will get damaged after one to two years. It will finally get leaked and the electrolyte in the battery will get in contact with the battery contacts at the battery comartment. This electrolte will react with metal contacts at the battery compartment which in turn supplies the battery voltage to internal circuits of the remote control handset. If these contacts get rusted due to this electrolyte contact, supply line to the remote control will be interrupted and the remote control will be ded, even after replacing it with new batteries. First thing to check with for a dead remote is this battery contacts. If there is rust or dirt accumulated, clean them using anything like a razor blade, very small file [seen with some nail cutters]. If the fault was due to battery contact, this process of cleaning will rectify the problem.

To cleean the inner circuits of the remote control, you have to open the remote control. Most of the remote controls' case are 'press fitted' with lower and upper case parts. There may be 4 to 6 of such locks. Some remotes will have screws also. Detach the lower and upper case, by using any sharp tool. A guitar pick will be efficicant ot do this work. Just look for the locks at one side, press the lock position inwards and try to lifit up or pull out the case part. Do this work with causion and patience. Never try to get it apart quickly. Get the case open without breaking it.

Inside the remote control, you can see a printed circuit board, with carbon tracks, and IC two or three other components, and an infrared LED. Check the soldering terminals of the infrared LED [two solderings] for any loose solder. If loose solder is detected, resolder that points by applying a little more solder.

Cleaning should be done very carefully. Never use strong solvents like petrol. Rectified spirit is most prefferable. Medical quality turpentine can also be used. This can be bought from most of the medical shops. Just dip a piece of soft cloth in thes solvents, and wipe out the carbon track and inside of the touch pad. If you use pwtrol for this purpose, the rubber part of the touch pad will get damaged and will turn stiky. After clean up, let it dry under a fan for some time. Reset the unit as it was before. If no other damge ot IC or other components is there, the remote control should work properly.

TV Remote control stopped working. I changed the

It depends. If this is a remote for a satellite receiver, you may need to resynch the remote (see your manual - I know the Dish instructions).

If this is a TV only remote, you might try opening it and cleaning the contacts with an can of compressed air, electronic contact cleaner and a clean pencil eraser. However, recent remotes are like keyboards (membrane contacts) and this doesn't always work. In that case consider a universal remote to replace the bad one or look to see if has a duplicate of your remote.

I hope this helps.

(for Dish, it is turn on the TV and the receiver, hit the Sys Info button on the receiver, then hit record on the remote. Then hit Select on the remote.)

My sony remote control does not change the channels using channel change button

looks like you change channels too much, with the result the inside rubber contacts have eroded. if you know how to open it and clean the channel contact with alcohol and put everything back together. most remotes have screws in the battery compartment, but you have to pry open CAREFULLY but pressing side cover joints for hook to be pushed in with gentle pressure. you may have to use two flat screw drivers to pry open side. This may or may not work depending on what and how you do it. Experts can do it.sometimes i have to put silver foil inside to make it work. GL

Lol?Anywho it could be that.What it is though is far from sticky.Buttons have pressure "receptors" on them that pick up pressure.Otherwise the wires might have been frayed or come undone in the remote control.In that case contact a proffesional or buy a new remote.Hope it helped

Samsung TV remote. I noticed today my TV remote wasn't working. I changed the batteries and noticed there had been some leakage from the AAA batteries. Since changing the batteries the 8 buttons on the top...

Giving you some hints. Battery leakage is one enemy of tv control and other remote control. They can corrode your battery spring contact, give contact bridges with neighboring tracks that can cause erratic behavior of your remote.

Some repairs can be done but doesn't guarantee success. First is try to clean the corrosion on battery contact = no power usually. Erratic behavior cause by contact bridging = battery leak residues.

Opening a remote control. Some have screws on its small foot. Covered by a rubber or sticker. Some are notch clip in strategic location you have to fry that one by one, opening first on its weakest side. In some don't want to be open.

Cleaning the board by a soft eraser is one way. After you open the remote. Commonly the button area where contact takes place.

If the first procedure and cleaning doesn't work. Buy new remote or use universal remote controller.
