The power is blinking because there is a deffective parts... the supply that makes oscillation of tv has been cut off... either the horizontal transistor is open or the resistor from the abl change its value...if you have knowledge with the parts maybe you can try... only the qualified servicemen can repair the problems...

The power indicator light is blinking. Tv will not turn on... Toshiba model 32HF72 I have tried to reset...wont reset


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 from bangalore.....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact toshiba service centre.........

Remote code for one for all urc 4220


HI,

To search for a code for your TV:
1. On the remote control, press TV once.
2. Press and hold SET until the LED (red light) blinks twice,
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
first.

5. To lock in the code, press and release SET.The LED will blink
twice.
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.

Toshiba 34" HDTV "standard" TV...not a flat panel....


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

TV turns off by itself after being on for 60 seconds


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

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.
