Re: LG 42PC1DA distorted pinkish when turned on
I'm going to ground on the screw nearest the VS, VA connectors... not on the scree I used last time.

Re: LG 42PC1DA distorted pinkish when turned on
So tried it again with the meter away from the tv...
First I got a steady reading for a good 20-30 seconds.. I figured the I had gotten interference before. But, then I took the probes off and back on and was getting the erratic readings once again. It goes up wildly... 155, 220, 300, then back down and steady...
So at this point I'm a little unsure.
By the way, I had my phone in my pocket and now its dead... coincidence?

ok retested during the fault. the voltage is not stable.. it stays at 99, then every few seconds jumps randomly 122, 130, 219, then back to 99 for a few seconds, then it repeats.Leave a comment:

Re: LG 42PC1DA distorted pinkish when turned on
ok so the red probe should touch the black square and the black probe should touch the screw... ok. But, is this with the tv turned on? (novice remember
)

Re: LG 42PC1DA distorted pinkish when turned on
OK here is where I hope you bear with me.
I have never used a multimeter.
I purchased one today.
I have taken pics of the z-sus board.
I have identified where it says Vzbias. it is towards the bottom of the board on the first picture.
I will try and take a clearer picture tomorrow.
Can you explain how I would test?...Last edited by zango123; 08-15-2013, 07:06 PM.Leave a comment:

Re: LG 42PC1DA distorted pinkish when turned on

Re: LG 42PC1DA distorted pinkish when turned on
Finally was able to get back to looking at the tv.
I opened up the back of the tv. Did not notice any caps that looks bulged.
(a LOT of dust though)
When I turned on the tv it looked crystal clear they I heard some slight pitch changes coming out to the power supply, and the image become distorted and pink/purple hue.
I applied heat using a blowdryer to all components one by one, no effect.
I have made a video of the tv when it is distorted: [URL="http://youtu.be/32y5i0lhZdw"]http://youtu.be/32y5i0lhZdw[/URL]...Leave a comment:

Re: LG 42PC1DA distorted pinkish when turned on
ok, I will try heating. When I open it up is there anything I should look for initially, like bulging capacitors?Leave a comment:

Re: LG 42PC1DA distorted pinkish when turned on
I'm a novice when it come to electronics repair.
A capacitor on what components
But, can I just take off the back of the tv and apply heat with a hair dryer to the components to see if the image will clear up faster?Leave a comment:
