If you have a voltage meter there are some things you can check.
Unplug the unit and remove the back cover of the set. Then Plug the unit back in.
You will need to tape down the lamp safety switch in order to do these tests.
Here are all the failures that would give you a lamp error and what to check.
Cause 1. Unit powers on and works properly for a while then shuts off with a red lamp led(lamp error). Suspect bad lamp and replace.
Cause 2. Unit does not power up correctly and you have red lamp led(lamp error). Check the lamp enable line at connector J14 on the back of the light engine. If pin 6 does not switch to 5 volts after turn on, but your 12 and 5 volt supplies are good, then suspect a defective light engine.
Cuse 3. At power on the lamp turns on and off 3 times and then the unit shuts down with a red lamp led(lamp error). You have a defective light engine.
Cause 4. Unit does not turn on correctly and you have a red lamp led(lamp error). Check for 12 volts at connector J9 pin 4 on the light engine. If voltage is missing check for an open fuse F9A09 on the power supply board. If it is open, then you need to replace the fuse and you still have a defective light engine.
Cause 5. Lamp enable line at connector J14 pin 6 on the light engine does go to 5 volts at turn on, but does not drop back to 0 volts after 5 seconds, but your 12 and 5 volts supplies are good then you have a defective light engine.
Cuase 6. Check for 5 volts at connector J9 pins 1 and 2 on the light engine. If low or missing check Capacitors C9A37 and C9A38. Values are 3300MF/10V. Replace capacitors if defective.

This is all I have and I wish you luck.

Hi W Bloom,


First of all, thank you for contacting Fixya.com regarding your TV problem.


My first advice is to do system reset by pressing the "Power" button key at the front panel and hold it for 10 secs.


Please check also if you can access the "Error Code Log" by pressing the "Menu" "3" "5" "6" "4" in sequence before the unit gone to shutdown.


You've mentioned that the bulb has been replaced just last Sept and now it won't come on. The lamp can't be test using the multimeter but you can make a visual inspection to determine its condition. Most of the faulty lamp has an obvious burnt mark. There's a possibility that the symptoms is caused by busted lamp but in your case, if it is a genuine lamp replacement, then high chance that the fault is not the bulb.


You need to check the ballast board but not the high voltage output of it feeding the lamp. No voltage coming out from the power supply board to the ballast board can produced the same symptoms. You have to check the this voltage at connector CJ1, you must get 325V to 340V. Check also the lamp enable at connector CJ3(pin 4) you must get a low voltage upon turning on the set to confirmed that the mainboard giving a signal.


If there's no voltage at CJ1, then the fault is on the power supply board.

If the readings are normal, and still the ballast won't ignite (you can hear a slight snap sound when the ballast board trying to ignite), then you have to replaced it.

green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

I would suggest it is a ballast problem. You can check supply of 5 volts to ballast's small 5 pin connector (trigger voltage) and about 300V-330V to large 2pin connector. If both voltages present at the start and lamp is working with in another TV - it is bad ballast.

After replacing lamp the red lamp light remains on. Lamp will come on for a second then go out. About a minute later the red lamp light comes on and unit shuts off.


Check the lamp door to make sure it is seated properly I believe the red light indicates door switch problem. It shows you lamp error data in the service manual.

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Tv wont turnon afterstandby


LG will sell you a new lamp. It may resolve the problem but just as likely it's the contacts where the lamp unit plugs to the TV. There's a few types of connectors. The early ones are dodgy and cause the problem you describe. A faulty lamp can also cause it though.

Red light on no picture will work fine after several minutes


There is a list of things you need to check, but offhand I'd say that the 5 volt line is low and probably right on the"edge", which is why it works sometimes and not others take a look at this list:
Cause #1
1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for
12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check
for an open F9A09 on the Power PCB, if it is open replace F9A09 part #
283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out)
Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if
low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the
Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three
times and then the unit shuts down with a red lamp LED (lamp error). Replace the
Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch
to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low)
after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB
(ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-
volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010

I would say try #3 first, the two caps on the pwer supply board. A couple of warnings: as always, unplug the unit before servicing. The power supply is located on the left side, if you behind the unit. It is in a shielded box and the shield has VERY SHARP EDGES so use care when you try to open it or you will slice your fingers.
Please be sure to rate this solution. Thanks!

Green light flashing & no picture on Toshiba 40pw13p


There is problem with the lamp. It might need to be replaced. The lamp unit is on the bottom-left side of your TV. Loosen thumb screw (by hand) to take the the lamp unit door. Using a screwdriver, loosen two screws of the lamp unit and carefully pull the lamp unit out.
Put a new lamp in reverse order.
