Question about LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television

1 Answer

TV screen turned on for only 10-15 secs then self turn off, followed soon after by the tv power another 10-15 seconds later. if i try this a few times screen wont light up at all.Is it the TV Lamp?

My TV suddenly developed this problem after someone with no knowledge of the LG TV/STB Remote tried to turn it on without success! I then tried to turn it on and here is what happened: Initial the amber light blinked as is normally the case when being switched on, then after a little while, the green light switched on and so the TV screen lights up; everything is normal so far... until 10-15 seconds passed the screen for no reason suddenly went BLACK!(the lamp self-turned off), however the power indicating (stand-by) light is still green for at least another 10-15 second before it also self-switch off to red! If i turn it on again, then the TV screen will only light up for even shorter time! and then similar results. If i persist with this after 3-4 times the TV screen won't even light up at all... I also checked the Lamp and when it went off matched that off the TV screen. I want to replace the lamp but not sure if this is the problem? hope someone can help. many thanks HT

Will Not Turn On


First you need to do a self test diagnosis and then if it comes up with:
SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
Do self test by pressing Input/Device and Menu at the same time for 5 sec. the set will show a 2 digit seq. first blinks followed by a short pause then the second.

Magnavox error codes


check this
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

Turn power on, approx. 30 sec later it the power


It varies as to what is actually making the TV shut down. Shorting the connectors on the A.C. plug have nothing to do with it turning back on. Its just the fact you are unpugging it for a few moments.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Hi John This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
