Lg plasma 42PT85 power on issue

Hi, I have an Lg plasma 42PT85. The issue is that when you try to switch on, at the on switch, or via the remote, you have to press several times before it will power up. It will eventually make a noise then switch on. It is always worse when it is being powered up for the first time in the day as it seems to be okay once the tv has warmed up. My question is do you know what the problem may be and if so the part I need to purchase to repair it. Kind regards, Callum.

SOURCE: SVA HD4208 PLASMA PANEL TV.

SVA is a manufacturer based out of China. Their headquarters is based in LA California. They specify in affordable plasmas and LCD's which are typically a generation or so behind other LCD manufacturers or plasma manufacturers. I have heard of this issue both in the power cord and internal parts of the TV's. Is it still under warranty? Otherwise, you can purchase another power cord. Contact the manfuacturer for those small parts.

SOURCE: Olevia LT42HVi - Need to toggle power switch on back of TV off/on all the time

You swapped the power strip. How about swapping the cord with another. Most LCD and Plasma TV used a cord similar to the cord use for the power supply of PC (IEC line plug). If still it doesn't work. Time to open the back to access the connector terminal which came loose (Due to heat) if not soldered directly to the power supply PCB. Just pinch the spade crimp, better still solder it. Make sure to lay the TV flat, face down on a smooth surface table if you're repairing it yourself.
Good Luck.

SOURCE: Power Up Problem

You have a 8.6v supply error according to the 7 error code being displayed, what you can try is when the set goes to blinking disconnect the Y sustain board (if looking at the tv from the back the board on the left) from the upper left side of the power supply, if the error code stops then you know your Y sustain board is pulling down your power supply and causing the error, if the error code continues you have a probelm with your Logic Board (located under your Small Signal Board) disconnect this from the Y sustain board and see if the error code stops if it does you know that the Logic board is bad, if the error code is still blinking then the 8.6v supply line from the Power supply is faulty and the Power Supply needs to be replaced

SOURCE: Phillips 42FD9954 plasma will not turn ON

I have a Phillips 42FD9954/17S and every time I try to turn it on I also get the power red light blinking and sometimes it will try to turn on with a bunch of clicking noises and it will be green for a while then turn red. What I do and its very weird but works, put a blow dryer on hot and blow it under the tv on the side of the power button for about 10 minutes and it will turn on. I took it apart and there is a heat sink that if i put the blow dryer directly onto it on heat it turns on in less than a minute. Can someone tell me how I can fix this heat sink? I cant take it off. I want to put some thermal compound to see if that works. Give it a try I promise it will work. The Red Light has to be on put the heat on it and then press the power button, if you hear it clicking and green then back to red you are almost there. Keep putting heat on it and it will turn on.

SOURCE: Panny TH-42PZ80U Plasma TV No display on Power-up

I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!

42 inch LG Plasma TV Lost Picture


Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok

50 inches LG PLASMA TV TURNS OFF AFTER 15 MIN.


A blown capacitor might not be the reason. After 15 to 20 minutes of work, the temperature inside the set do rises much, this kind of fault can occur. Check its cooling fans.

Lg plasma menu screen wont go away


The exit button on the remote may not be working or some other button on the remote is jammed. Try removing the battery of the remote and switch off the TV manually and the input power. Wait for a few minutes and then switch on the TV manually. The try changing the menu from the TV control panel. If nothing works, this is a case to be handled by a qualified service technician.

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

Connecting laptop to LG Plasma via vga cable


you should have a button that you have to press to get it to switch over, on mine i have to press and hold the Fn key then press the F4 key might not be the same on yours but you should have a f something key that has what looks like a little screen on it that is to switch the output if that does not work try hooking up your laptop just like before, and then restart it. good luck
