I have what appears to be a 21 code

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://electro-medical.blogspot.com/

Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

it's possible to unlock with a remote control.I Used a "One-For-All" remote.
This process is working on more that this Sony DVD players.

First prepare the remote control to use right device code.
1: Select the DVD button on the remote
2: Hold "Magic/Set" button util the LED blinks twice (Rabbit appears)
3: Press numbers 0533

Now program the remote control to send special codes on button 1 to 5.
1: Hold "Magic/Set" button until the LED blinks twice (Rabbit appears)
2: Press numbers 994
3: Press "Magic/Set" button once
4: Press number 1891
5: Wait some time
6: Hold "Magic/Set" button until the LED blinks twice (Rabbit appears)
7: Press numbers 994
8: Press "Magic/Set" button once
9: Press number 2552
10: Wait some time
11: Hold "Magic/Set" button until the LED blinks twice (Rabbit appears)
12: Press numbers 994
13: Press "Magic/Set" button once
14: Press number 0953
15: Wait some time
16: Hold "Magic/Set" button until the LED blinks twice (Rabbit appears)
17: Press numbers 994
18: Press "Magic/Set" button once
19: Press number 2214
20: Wait some time
21: Hold "Magic/Set" button until the LED blinks twice (Rabbit appears)
22: Press numbers 994
23: Press "Magic/Set" button once
24: Press number 0795
25: Wait some time

Now the remote is ready for use on the DAV-X1
1: Start the DVD without any DVD in it.
2: At the same time press and hold "Eject" and "Stop" in and then press "volume +" to get into the service menu
3: Now use your programmed remote
4: Press button 12345 with a small pause between each num.
5: Press button 12345 with a small pause between each num.
6: Wait some time
6: Press button 12345 with a small pause between each num.
7: Now use your orginal remote and turn the DVD off

Tested to play Region 2 and Region 1 DVDs without any problems after this. (The remote i used was a Cameleon 6)

Hi
You need to follow these instructions.


To unlock the Region Code on a Panasonic DMR EZ48 using a One for All - URC 7040



1. Switch on the player (make sure the drive select is DVD).
2. Select DVD on the URC.
3. Hold the magic button on the URC until the DVD button on the URC blinks twice
4. Enter device code 0490 on the URC, (DVD button blinks twice), URC takes control of the Player.

Point the URC at the Player and program the URC buttons using the following procedure:

1. Hold magic button until the DVD button on the URC blinks twice
2. Press 994 (DVD button blinks twice)
3. Briefly press magic.
4. Enter 4 digit code 1911 (DVD button on URC blinks twice)
5. Repeat steps 1, 2 & 3
6. Enter 4 digit code 1202 (DVD button on URC blinks twice)
7. Repeat steps 1, 2 & 3
8. Enter 4 digit code 0653 (DVD button on URC blinks twice)
9. Repeat steps 1, 2 & 3
10. Enter 4 digit code 1804 (DVD button on URC blinks twice)
11. Repeat steps 1, 2 & 3
12. Enter 4 digit code 1435 (DVD button on URC blinks twice)
13. Repeat steps 1, 2 & 3
14. Enter 4 digit code 1556 (DVD button on URC blinks twice)
15. Repeat steps 1, 2 & 3
16. Enter 4 digit code 1227 (DVD button on URC blinks twice)
17. Repeat steps 1, 2 & 3
18. Enter 4 digit code 1178 (DVD button on URC blinks twice)
19. Repeat steps 1, 2 & 3
20. Enter 4 digit code 1299 (DVD button on URC blinks twice)
21. Repeat steps 1, 2 & 3
22. Enter 4 digit code 1230 (DVD button on URC blinks twice)

23. Press the One For All URC buttons in the following sequence

1, 2, 3, 4, 5, 6, 7, 8, 9, THEN hold down 0 until "HELLO" appears in the display;

After about 1 minute the Player comes back to life as Multi Region.

TWO QUESTIONS:

1.) DOES POWER LIGHT JUST BLINK?

2.) IF POWER LIGHT COMES ON FOR A SECOND OR TWO AND GOES OUT, do the self check this set has:

when light goes out press and hold both the menu and input (device) buttons at the same time on the front of the set for at least five seconds and release both.

Power light in this case will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code you find and I will help you.

do self check: when it shuts off and power light goes off:

On front of set press and hold both menu and input (device) buttons for at least five seconds and release both buttons.

Power light will blink a two digit error code, like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code and I will assist you

The TV indicates an error code 22 (short circuit protection). Check 2 STK392-570 convergence IC for shorts and 5amps pico fuse for open. I usually replace both STK's.

Try this and let me know what you find:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY

if your set does not have a device button press Menu and Input together for 5 seconds and release. there will be a pause between blinks---2 blinks, a pause and two more blinks etc.
