My LG 60PH6700 plasma TV recently started acting up. Red power light but no sound, no picture. I've replaced the YSUS and Y buffers and the symptom persists. Any other ideas on this? Many thanks.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

HOW DO I CONNECT TO THE INTERNET MY LG TV MODEL NUMBER 42PA4500-ZM POWER AC 220-240V 50/60 HZ 0.90 A SERIAL NO : 207MAUA2Y862


You read the manual and it will tell you, except in your case it won't as it is not a Smart TV with internet capability. It is a plain and simple television.

LG 55LM4600-UC LED TV I have was squirted with a squirt gun. Would replacing the t-con board fix this tv? Please read further details.


when water shorts out something it overloads a lot of other components so the best advice is to take it in for a proper diagnosis.
you just replace a board but another board is damaged it might just blow the board you replaced and that would prove nothing

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.

I have a lg tv 60 inch tv ln5600 when powering on red stand by light blinks 3 time then no light pic or sound not backlight and no image when using flashlight treid replacing power board does same


Those 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.

How to program my lg magic remote with my dish tv box


I'm wondering if the original question "How to program my lg magic remote with my dish tv box" was ever answered, and if the problem was eventually identified and resolved. (none of the answers above seem to be solutions).
I have the same problem - unable to control my Dish receiver (VIP722K) with my new LG Magic Remote - and LG support wasn't able to help. Is this a known compatibility issue?
