Question about LG 42LG50 42 in. LCD HDTV

Open Question

42LG50-UA no picture, no sound. On power up, get 5 red flashes, then steady blue indication. Tried multiple video sources. Got lucky for a brief time when picture and audio came up nicely, time enough to browse the setup menu. Then picture went pink and got memory dump of some kind. Now, back to no picture, no sound.

Sounds like power board. You cannot tell if capacitors are bad just by looking An ESR meter is required to test them

When i turn on my LG 32lg30 on, the power indicator light flashes red 4-5 times, then the monitor turns on to a steady dark blue color. I tried to press buttons on the remote but there is no display.


Now there is a challange.
My LG has not shown this behaviour yet. Do you still have the DVD disk that came with the TV.
If you do you will get your answer there I presume.
Make sure that you are using the correct input.

Bluetooth wont charge or power on. when charging the red light comes on. once disconnected from charger it wont come on


Indicator Lights:
1.Headset Status Headset Indicator Light
2.Powering on Steady blue, then intermittent flashes
(changes to standby mode)
3.Powering off Red appears and goes off
4.Standby Blue intermittent flashes
5.Charging battery Red solid light. Light indicator turns off when
battery is fully charged and headset is off.
6.Low battery Triple red flashes
7.Pairing mode Blue/red alternating flashes
8.Missed call Purple flashes. Press the call control button
to cancel flashing light.
9.Incoming call Triple blue flashes when ringing.
Power on and off:
1.Turn on the headset Press and hold the call control button until the
indicator glows blue. You will hear ascending
tones.
2.Turn off the headset Press and hold the call control button until the
indicator glows red. You will hear descending
tones. When power is off, indicator stays off.
If none of this is helpful then it may be that your battery is dead, if that is the case then you will need to replace the whole headset. The battery's are not replaceable.

Good luck from Headsets Direct!

Blue light blinking-


I would say you are lucky to get a pretty fair price, sounds like a convergence problem- if the tv is a projection wide screen. worth the investment Julio milleniumtvsvc@gmail.com

Good Day, luap356;

Look for fluid on the PCB's, if don't see any try this:

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. SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB. Good Luck, big IRISH.

No picture or sound


On mine the indicator light is indicating that it is in STANDBY mode, which means it is OFF. Press the button again, which will turn off the light and now the tv is ON. Now merely press(possibly multiple times) SOURCE to find the correct source for your Cable/SAT and your good to go.
