Question about Toshiba 27A34 27" TV

7 Answers

Remote control will not work

The Remote is sending the signal, but the TV is not reading. Maybe the Sensor went bad I have the same problem with my 27" Toshiba TV. Model # 27A43. Remote won't work, even with new batteries. I purchased a universal remote and that won't work the TV either. TV works fine manually but I cannot get it to the DVD or VCR mode without the remote. I have ordered a remote receiver from Fox Intl. Is this easy to replace? What is the procedure?

    I don't think you understood the question. I do not need to replace the remote. I need to replace the sensor in the TV that is the reciever for th remote. The problem is not with the remote.

  • whanson Jun 30, 2008

    I need the procedure for a 27" Toshiba in replacing the sensor (or remote reciever as Toshiba told me) in the Television set itself.

  • morneault Jul 20, 2008

    I have a Toshiba TV remote problem also. I am on my third remote and continue to have intermittent control with the remote so I purchased a universal remote and have the same intermittent control.
    I suspect the problem is with the TV.
    How can I replace the sensor in my TV?

    Remote control does not respond to the television. Television//vcr/dvd works excellent when operated manually. I think it may be the sensor on the Televison unit.

That is certainly unusual for a remote receiver to go bad unless it was struck directly or exposed to damage. Anyway.... the procedure obviously involves getting to the PCB to replace the module. I've not worked on that exact model, but all CRT televisions are similar, and that one is made by Orion.

There really are two options: Front and back.

You can go in the back way, by removing screws and such until you can pull the rear housing off. Make sure you first unplug the unit for about 15 minutes. Leave it unplugged.

If you are uncomfortable doing this, then, please, buy a new TV.

I STRONGLY suggest that you discharge the main capacitor by grounding the anode. If you don't know what this means, then buy a new TV. You don't need a special tool, just a long, flathead screwdriver grounded with a wire to an earth ground will do. If your are afraid of getting shocked, buy a new TV.

The CRT will be mounted in a chassis attached to a main PCB at the bottom. It will be screwed to the housing face. You will have to separate the chassis/board from the face of the housing also, being careful to remove all the screws around the front input assembly. The housing removal is quite easy, but it will take time. You will then be able to locate the IR module at the front of the board. Carefully de-solder it and install the new one. Reassemble.

Somethings I would do before I undertook this venture:
Be ABSOLUTELY sure that the IR module is at fault. Not the remote.
Check the IR module for 5V at Vcc to rule out a faulty IC.
Confirm replacement module is similar in pin-out, freq. (bandwith), voltage
Reserve a good afternoon block of weekend time.
Chill some brews.
Create a large work space if you don't have a bench. And if you do have a bench, clear some space.
Be prepared to be without this TV forever, because everyone screws up sometimes.

The front inputs may give a bit of trouble. Take it easy there if you wish not to break anything.

If you are afraid to open the back. You could always go in the front. Unplug. Dremel a hole under the IR module using a depth limiter. Remove Vcc from existing module. Piggy back new module. Tada! Cake. Remember that is you put it under the board, the pins will be reversed.

If you are careful enough, after the anode, there is not much to screw up besides some broken plastic or bent front inputs.

Good luck.

Have you tried this Whanson? ? Each time you replace the batteries, you must reprogram the remote control. ? Some newer VCRs are capable of working on either of two remote codes. These VCRs have a switch labeled ?VCR1/VCR2.? If your VCR has this kind of switch and does not respond to any of the codes for your VCR, set the switch to the other position (VCR1 or VCR2) and reprogram the remote control. You can try to reprogram the remote or switch to VCR1 or VCR2. Just post a reply if you will still have a problem.

You probably can replace this, but this will likely cause a problem with warranty. If the computer is still under warranty it is recommended to return it to the manufacturer. If not, are you familiar with working on televisions. If you do not feel comfortable we can help you find a local technician for assistance.

SOURCE: Toshiba CZ36T31 will not respond to remote control

Finally hod this fixed. Toshiba gave me the names of 3 authorized repair shops. They all wanted between $150 - $200 to come to the house and do the repair. They cited replacing "the processor" etc.

But my brother-in-law had talked with a chinese man in a mall and we spoke to him. He said probably no need to replace anything. If he came to the house and fixed it with no parts it would be $80. If he couldn't fix it it would be $15 to cover the cost of the gas.

So he came the same day, in the evening. Turns out it was a cold solder problem with the diode that feeds power to the IR sensor. Took him 1/2 hour from the time he came in the front door, fixed it, and left. Just goes to show you what old time service and understanding can do. Most repair techs today only know how to replace boards not to really trouble shoot for the obvious.


respect....

Peter

SOURCE: uneiversal Remote Code

The model of the TV is not important as the code list is by Make only and usually list 3 ot 6 codes to try for each make. Having the Remote control model number is more important so you can find the right instructions and code for your remote.

I have a e422vle Vizio TV. The power board went bad, I ordered a new one and the Tv now is working but the remote doesn't work. Is the remote sensor on the power board?


Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Pull up older posts. If the remote control is found OK; check and replace the infra-red sensor inside the TV.

It reads TEST in the display screen and will not change


follow this steps and fix it. God bless you

Either the remote or the receptor on the device is not functioning.
Use an Intraed Sensor to see if the remote is sending a signal.
If the remote is sending a signal, it used to control that device, and no other solution works, you should have a service center look at the device and remote to determine the problem and if it can be fixed.
If the remote is not sending a signal and you have replaced the batteries, you will need to repair or replace the remote, depending on cost.

My samsung led remote control has just stopped working and i can't get it to work again. I've changed the batteries and i cannot find the reset button. I've unplugged the power from the wall and still no...


We need to find out first if the remote is putting out the IR signals or not, or the problem is in the TV IR receiver module.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Remote control No work


Try another remote control, if it is also not working that means remote sensor in tv got bad and become unable to receive remote signals, replace remote sensor in tv.
If other remote works then replace batteries in bad/ suspected remote and check.
Let me know model and brand of your tv if you have additional question.
Thanks.

Also look at the back of the TV to see if it has IR input jack, if it does, then the switch inside the jack may have to be cleaned.

you should get the original replacement remote here: http://www.replacementremotes.com/store/productdetailp.cfm?productid=27278

My remote control does not work


You could have a defective IR sensor in the tv set that sends the infared signal to the MIcroprocessor IC. These are something you cant just replace, as it needs to be trouble shot with a scope to see if theres a data signal comming out of the sensor and if there is it could be a bad solder connection somewhere between the sensor plug to the Main IC. Also could be the B+ that supplys voltage to the sensor. Unless you have had electronic repoair experience, You should have a pro assist you with this repair. Sorry I couldnt assist you more with this . Good Luck
