The Service Default Mode (SDM) is a technical aid that can be used to display the your TV error code.
Follow these instrutions exactly to place your set in SDM Mode.
For sets that still have video do the following.

1. Turn your TV on
2. Using the original Philips TV remote press the following keys. Press each key for 1 sec then press the next.
3. From the remote press 0 6 2 5 9 6 MENU
4. You should now see the letters "SDM" in the far right hand corner.
5. If not do step "3' again.
6. To display the error code hit the "Status" button on your remote.
7. The TV can store up to "7" past errors.

For sets that have no video do the following.

1. Turn your TV on
2. Using the original Philips TV remote press the following keys. Press each key for 1 sec then press the next.
3. From the remote press 0 6 2 5 9 6 MENU
4. Wait a few seconds. The red power light should begin to blink.
5. The blinking sequence will determine the error code.
6. You will have one long 5 second red blink followed by the error code.

Note: On some sets the TV will automaticaly blink the error code when its powered up without having to go into the SDM menu. If you power light blinks after the set is powered up jot down the sequence.
Example Error Codes from the power light.
( RED 5 Seconds ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) = Error Code 3
Example #2
( RED 5 Seconds ) off ( RED 1 Sec ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) = Error Code 12

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

The red light is indicating the set has shut down for a specific reason. You can dtermine the reason by going to the sets front panel and pressing the menu button and the device/input button both in together and hold for 6 seconds. The light will switch and begin to blink a series of blinks( First number) and pause briefly then blink another number of blinks (second number) then it will repeat that same two digit blink code. Let me know the code and I will let you know what happened to shut the set down. Respond to this same post for assistance.

Lamp needs to be replaced,

Turn the power off. Hold down the up arrow, down arrow and Economy buttons all at the same time and hold for three seconds. A series of lights will start blinking. Write down what you see. You may have to do this procedure again because the codes blink fast. Look up the codes in your owners manual or post the codes again on fixya and we can get you a starting point where to look. I suspect a flame failure because of a dirty flame rod or debris lodged in the burner.

set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

this set has a self diagnostic feature:

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}


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.


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 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
CONVERGENCE CIRCUIT PROBLEM

This set is equipped with LED diagnostics. Once it shuts down on the front of the set hold down the MENU and INPUT, (sometimes labeled DEVICE) buttons until the LED starts blinking a 2 blink sequence. For example one blink pause two blinks long pause and then repeats is the code for no problem. All of the fault codes begin with two blinks and then one through 4 blinks. I suspect that yours will be a 2 - 4 code because of loss of vertical sweep. Which is bad solder connections on the deflection yokes. A common problem with these units.

press and hold the menu and device/input buttons both in together for 5 seconds then the led will blink a number of blinks pause then blink another number of blinks then repeat that process. Let me know thw binks you get for the two digit blink error code.
