CRACKED INNER SCREEN OF A 50 INCH LG PLASMA FROM NO EXTERNAL DAMA

If nobody at home how was the tv on?!?!?!?!?!? U must have a poltergeist living there if you stick to that story! Screens do not just crack all by themselves - they need a little help. And product warranty's do not cover abuse. So yeah, you will be eating the 2 big ones.

If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have LG 50PC3D 50 plasma tv. Remote now changes channels only and to on/off and volume control have to get up! do it on tv. Had it fixed twice but problem comes back. What to do?

If repars are recent take back and ask them to do it right, if tv less than a year old lg should replace remote. Otherwise I would replace whole handset either with a new lg 1 or get a universal that is compatible with the tv

LG 50PC3D PLASMA WILL NOT TURN ON

Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!

Turn on tv, red power light flashes green three times and turns back to a steady red. Prts to repair or replace?

These 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. http://electronicshelponline.blogspot.com/ Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

T.V. works fine but makes a lot of noise from within

If it works fine; there is no problem with this noise. In most cases, the noise can be with the cooling fans inside it [top side]. Check whether any block is there dust or something else.

Image and colors "washed-out"? What causes this symptom and which circuit board needs to be replaced?

typically this is caused by the imaging processor. The board can be swapped out but requires a good bit of know how as there are a lot of dangerous components in LCD and plasma televisions.

50 in lg plasma wont turn on just clicks

hi,
you have to check the power supply first.

As u mentioned about the click sound, the 5v standby supply is ok. The click sound you hear is from the standby relay.
you have to check the other power supplies in the SMPS (switch mode power supply board) board.
first of all check the standby supply 5v on tne pin of connector P800. check the voltage at this point in standby condition and at the time of power on. it should stay at 5v. if it reduces the you have to check the components related with standby SMPS transformer T501.

If the 5v volt is ok the u have to check the 3.4 v at the pin 1 and 2 of connector P802, at the time of power on. if it is missing then check the components related to T112 ,also check the following voltages at the same power on condition.

19v at Pin 1and 2 of P803
6v at the pin 5 and 6 of P802
12v at the pin 9and 10 of P802

check these to verify your tv's power supply
proper care should be taken while working with power supply, because there is risk of getting electric shock.
if you need any more assistance fell free to contact me through fixya.
I have with me its field service manual ( does not have any schematics) if u need that i will sent it to you, if u give me your email id through fixya.
ok
