    We are a repair depot and have this TV in for repair. We have tried a new remote and have replaced the receiver remote sensor. Have you had any other problems similar to this for this model. Could it be out of frequency. Thanks.

The remote sensor or the remote itself may be bad. The cheapest and easiest solution to try:
I would just get a universal remote and program it for the TV with the code they provide. You can pick one up for around $10 at practically any store. Walmart and Kmart seem to be the cheapest. A factory replacement remote is a rip off.
I hope this helps and good luck!

    This has worked in the past with infrequent results, but it is worth a try. Remove the batteries from the remote, and go through each button and hold them down for about 2 seconds. If not and the remote sensor has been replaced you will need to make sure there is 5 volts
    on the sensor b+ line and that it is clean and has no AC in it or any
    noise. You will also need to trace the data line and make sure you
    have a good strong data signal comming out of the sensor all the way to
    the microprocessor.
    If the signal is good all the way to the micro, then replace the
    microprocessor. All these checks cannot be made with a meter. They
    must be made with an oscilloscope. Good Luck!

Need Toshiba remote access code for this product so I can use a universal remote to operate the VCR and DVD

remote codes are set by the manufacurer of the remote not the tv. if there are any others not listed in instructions for remote, the manufacturer of remote would have them. most combo unit are not able to be programmed into universal remotes due to the fact that there are alot of specialized function buttons on original remote. you can obtain a replacement remote thru toshiba

I can not get any remote to work on my toshiba 32a33 t.v.

Hi, I have same problem with olderToshiba 1999, Model CE27T11. I learned that a spider web, a bug dropping - live in Florida, or just plain dust can interfere with operation. Right now I am trying to disassemble the chassis, I have half of it off, but wires are holding it to the tube assembly. I took all the screws off, popped the back off, and now am at a standstill. The "dust" is interferring with the signal... to & from the remote. So I have been told...
I intend to vacuum it, and dust with micro fiber cloth, once I get it apart, the key is to not break any solders, so try not to blow the dust off, as this can break the solder. I too have tried a new Toshiba remote, a universal remote, and rebuilt and cleaned the old one. It is frustrating when it quits working and you cannot get it to work, no matter what you do.

Can't get cable remote to operate GE 19TVR62

I found these remotes control VCR's only when programmed into the DVD button. It even says on page one of the manual that the DVD button is for DVD's, TV/VCR's, VCR's, etc. I got code 607 to control my GE VCR (using the DVD button). If that doesn't work, try 572 647 563 609 644 645 or 531.

QA01 and QA02 did not had to be replaced there was a contaminant problem on solder flux that was causing the problem. kbzon
