Question about Toshiba CZ32V51 32" TV

1 Answer

Set Randomly Turns off (Power LED Blinks) and Comes Back On ~1-2 minutes Later

My 32" Toshiba standard TV has worked great since I got it in 2000. It actually still works great besides this problem. There is no pattern, but occasionally it turns off and the red power led on the front blinks for 1-2 minutes and then it turns on again. The picture and sound remain unchanged before and after this event. There is no standard time limit between when this happens. Sometimes it doesn't happen at all, sometime it will happen twice in an evening. The signal from my cable box is still there as I have been recording when it occurs and there is no blackout on the recording. Everything still works perfectly with this TV (except for this), so I was curious if anyone had any idea about what kind of repair may be required, or if there is something that can be adkusted.

My Sony KDS-60A3000 randomly turns off, then the red "Power LED" blinks three times repeatedly (not "Lamp LED"). We turn it back on, the process repeats again between 20-60 minutes.
3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. . 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/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

I need the steps to program the urc4021 remote, as well as the code for the sanyo tv
To program the One-For-All URC4021, first turn on the TV manually (or with the original remote). Press the TV button on the URC4021 once. Then press and hold the Set button until the LED blinks twice. Now you can enter a code directly and test it. For Sanyo TVs, the only programmed code is 0154 . If the LED blinks twice, press Power to attempt to turn off the TV. If that works, you can turn the TV on again and test if the other buttons on the remote work with your TV. If the LED doesn't blink twice, repeat the steps from pressing and holding Set. (If you wait too long before entering the code, the remote will leave the programming mode.)

The URC4021 has a code search mode. Press and hold Set until the LED blinks twice, then press 9 9 1 . If the LED blinks twice again, alternate between pressing the Power and TV buttons until the TV turns off. Then press Set to lock in that code and test the remote again.

I hope this helps.

Cindy Wells
(Note: if your TV is newer than the remote or released within 6 months of the remote being programmed, this code may not work. The URC4021 documentation gives March, 2004 as the copyright date. That suggests that the codes may not work with devices built in 2004 or later.)

Television goes off without turning off
your set needs to be repair by a tech you are having a problem in your power suply which is intermittent.either your hrizontal ic is shorting out, or your regulator or your microchip ic.or the diode that couple the collector of the horizontal transistor with the b+ from the fly back.or check for lose solder in the horizontal output or power supply. good luck

TV turns on but no picture and only blinking remote LED senser?
Try hitting the side of the set while you are waiting for the pix to turn on,dont over do it and see if the set reacts,if it does you will be looking for loose conections in the main board or crt board,these solder points need to be resoldered,if you are familiar with tv service it will be something you can do but if not be safe and call for help,the repair should not be expensive right now.
