Question about LG 42PG20 42 in. Plasma HDTV

1 Answer

I have an issue and I'm trying to diagnose if the TV is repairable or not. We recently had a lightning strike at our home and what is happening with my TV is that when you plug it in, the 'Power' indicator on the front automatically goes to 'blue'(indicating the power is on) and it is usually 'red'(power saver mode) when you plug it in and turns blue once you hit the power button. Also, I have no picture so 1.)Is this something that can be repaired? 2.)Is is something I can repair or do I need to take it to a shop? Thanks for your time and assistance!

Hi Russ,

I'm around 80% sure that the TV is repairable because by what you have explained it is still receiving power.
Have you tried a factory reset on the TV? If not try that if you can and see if the TV will come on. If there is no option to manually reset the TV then because of the lightning strick on your home there will have been a massive surge of power that will have damaged components in the TV. One of the components which will have no doubt been fried is the controller board and possibly other components too.
You are not going to know just which parts have been damaged until you take the TV to a shop to have it looked at where they can test all the components and circuit boards.
This could be quite expensive but on the other hand it could also be as simple as them replacing a coulple of semicontuctor chips or capacitors.
You could also investigate this yourself by removing power fron the TV, take off the back of the TV and inspect the main boards for anything that looks to have blown out.


Regards.

Did you have a power surge after a loss of power? If so your TV is ruined from the surge. In the future use a surge protector if don't already.

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.


Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Sorry.
Contact the authorized service center. OK?

Will a nearby lightning strike cause a power board failure?


It could happen yes it would depend where the strike entered the TV. Not all lighting strikes hit on the electrical lines, on a TV they can come through the cable, as well as a antenna if you have one hooked up.

I have a 51" JVC HD TV that is about 3 years old. Recently lightning struck my home and now I have sound but no picture. Is this set worth fixing and any ballpark figure on repair?


Lightning strikes are always tough because there is often hidden damage. By that I mean that the lifetime of some of the components might be shortened.That being said however, I would invest in a detailed repair estimate. Report the results here and we can help guide you from there. Without seeing the unit itself, remote diagnosis, especially in this type of situation, is tricky at best. You would be wise to have the actual unit examined. For a set of this size and age, the estimate is worth it.

Lightning strike came in via cable not power.


Your tv is going to need internal repairs. I recommend using our premium service to help walk you through these repairs. Or contact a local repair service.

To avoid this in the future I recommend an inline surge protector or a "green" switch.

An inline surge protector makes sure that all power to your tv comes through at the same level and does not spike or fall. It has a battery backup as well.

A green switch is a way of rewiring your home or your entertainment center to allow you to disconnect all power to your entertainment center when you are away, when a storm is coming, or when you are simply not using the system. A remot control can restore the power.

The average home entertainment center has one of the highest drains on electricity in the average home for appliances that are not in use. that is what makes the green switch appealing.

Surge from lightning strike damaged tv and won't turn on.


Unless you are skilled at trouble shooting power supplies , you will be better off getting a skilled repair center to repair yourset. If its repairable I have seen surges from lightning strikes make the set no longer cost effective to repair.

Lightning strike


Hello bkindle.....not a boat anchor YET!!!! Had similar problem with WS-55513 and it turned out to be a faulty DM board. There are 4 capacitors on the board that may have blown. If yo can solder, it is a pretty easy repair. I purchased a PDF manual for mine online to get familiar with the model.

Otherwise, you can expect to pay between 275.00 for a repaired board OR between 350.00 and 450.00 for a replacement board from Sears or Mitsubishi.

Hope this helps. I know it is frustrating but be patient.

Good Luck - Richard (MetalDad)

Color messed up on tv since lightning strike


your tv may have ben magnetized by the lightning strike.
tv's have an automatic degaussing circuit that demagnetizes
the pix tube when the set is turned on. this degaussing circuit
may not be working or magnetism may have been too strong for
the internal degaussing to correct.
contact local tv repair shop in your area see if they can manually
degauss your set , it should be a min. service charge around $25.
