20 Most Recent Toshiba 36A40 36" TV Questions & Answers

I would start with the Tcon but the main would do this as well, along with the power board...test the voltages coming from the ps board when its giving issues and see if they are ok, if they are try the tcon board

These input plugs are often soldered on to a printed circuit board mounted to the internal chassis of the TV. Much of the circuitry in a TV is lethal when switched on, and in some types, even when not plugged in for a time. Therefore I'd advise taking it to a repair shop and asking for a cost estimate. With parts and labour that might even approach the cost of a new one, for which you get a warranty. .

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

Short of it being taken back to factory reset via its menu system, which most will do in some way (Initial setup sequence) the other possible cause could be its tuner which may have a partial fault if so then it is possibly a service call out. Unless its a simple job, sadly these days it will have to go to a service centre contact Toshiba for a local repair place they will have better knowledge of your item.

From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes.

Press the menu button and find the auto search programs. wait till the end of searching then you can watch all the channels.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Sounds like a loose solder terminals at its vertical scan output section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/

Are you turning up on the tv itself? If you have a cable box, there is a separate volume that needs to be turned up too!!

the intrenal switch that controls the volume up is shorted. you need to have it replaced. the short of the switch doesn't allow any other buttons on the set to work because the micro is recieving the volume up command. it's as if there is an invisible finger pushing the volume up button. the switch is a tachtile switch which is very inexpencive to repair about $50.00 total. if you want to do the repair yourself be aware there are voltages that remain in the set that can be harmful. 50% of the time the cause of these switches shorting is improper screen cleaning. some people spray glass cleaner directly on the screen, this is bad. the cleaner drips into the set and lands on the PC board where the buttons are housed. but I've seen the other 50% also which is hummidity, dust(not anyones fault this just happens), and simple switch failure. so becareful repairing it your self

Bad capacitor in vertical circuit + possible vertical output IC
damage.If you can identify part locations and solder.....?

hi, usually its the infrared receptor that need to be replace, he is placed near the stand by light.
in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility
that something is wrong at the microprocessor circuit. good luck!

The fault is with its main board, horizontal output section circuit. This is not a user repariable fault.

How many times the timer light flahes at one time switch ON. These flashes are fault symptoms. From the number of flash, you can get an idea about the faulty circuit side, inside the tv. These flashes are called blinking codes. If you wish to get more details, surf the following link. There are over two thousand and four hundred posts. All are related to television and other domestic electronic equipment service help. You can get a solution there. Type in the brand name to your device to its search box, can be located at the top right of the display window. It will make search easy.
