Question about Toshiba 32A42 32" TV
Over the last few years my remote would work and not work. The batteries are new. Usually I would unplug it for a little while and my remote would work again. I tried powering it up with a universal remote and the TV remote. No luck. I can turn the tv on from the front panel.
Don't know where to turn.
Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. In some cases, the remote control might need to clean.

yes they do go bad. try cleaning the inside of the remote and check for a bad solder connection with-in the remote. the key pad can get dirty from your handling maybe a good cleaning but do not scrub it just lightly touch the pad with cue tip and alcohol

I had the same problem with my remote...over time it slowly stopped working. (sorry for poor terminology) I noticed that one of the battery terminals was corroded and that the metal connecting the battery to the board was completely gone. I simply swapped this out with one from another remote and now its working fine. Seems the only issue is that the battery was not connected.
I hope this helps.

This unit has a horizontal/high voltage issue. This is a dangerous circuit to work with so you should have a shop check it for you. Thanks for using fixya.

usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective - so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 (US$ 12) - iam service engineer (computers, laptops, printers,etc) - bangalore - domlur - 09986222774 - email@example.com - if you are in bangalore then you can call me for service - i think you are living somewhere in america /australia..... - problem is simple but i don't have any idea about EHT COMPONENT 's price & service charge in your place.......

Testimonial: "fast response. makes sense on a 9 year old TV"
SOURCE: I have an old Toshiba
This is a protection circuit that prevents the tv from coming on (to stop damage of the components) ....you need to check your voltages off the power supply and make sure they all read well (EX: 24v12v5v etc). The voltages your powersupply produces will be stamped on the board itself. EX: If it says 24v on the p/s board...read for 24v (23.9v is also "ok"). But, if you get something like 10v, then you have found your problem. Also, look for popped capacitors that would make the values lower than need be for the tv to power on properly.
Once you repair the power supply then you may need to replace other components if needed (EX: backlight inverter)! The backlight inverter is what lites the screen for viewing!
I would recommend to repair immedately and stop trying to turn it on over and over...this will futher damage your tv and cost more to repair, in the long-term.
Best of luck!!!
Please rate if this helps! :D
