Question about Toshiba CZ32V51 32" TV

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.

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.)

To search for a code for your TV:
1. On the remote control, press TV once.

then release SET.
3. Enter 9 - 9 - 1.The LED will blink twice.
4. Aim the remote control at the TV and slowly alternate between pressing POWER and TV. Stop when the TV turns off (after pressing POWER). If the device does not have a Power key, you can substitute another function, such as digits 0 ~ 9 , CH +, or PLAY).

NOTE: In the search mode, the remote control will send IR codes from
its library to the selected device, starting with the most popular code

5. To lock in the code, press and release SET.The LED will blink
6. To search for the codes of your other devices, repeat steps1 through 5, but substitute the appropriate device key for the device you are searching for.

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Red led blinks on / off, TV does not turn via power button and/or remote but after 20 minutes or so it turns on and works fine
Replace R902, R901, R905, R903, R900A, Q902, and possibly the two (one small and one large) capacitors in the section labeled as the power supply. The board will be black under the components that are bad. Q902 is an NPN transistor and is hard to find.

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.
