Replacing a panel control board on my LG RU42PZ61...

I have the new board and have the plasma partially disassembled.  I see the panel control board underneath the boards on top.  My question is this - Do the ribbon cables on the top two boards disconnect and do I need a special tool to remove them?  They don't have clasps on them and look like they attach to the board directly.  I tried pulling them off, but they seem very snug and I'm afraid to pull to hard.
Thanks for any tips.

Hi,

Not an expert, but managed to fix my 47" LG plasma a few months back.

You'll probably find that the ribbons will disconnect at one end or the other. I wouldn't recommend using a tool for the job, unless it's made of a soft material - I've ripped many a ribbon by trying to use a screwdriver or similar for extra leverage - fingernails are probably the best thing to use.

Try getting under the ribbon connector at one side or another. If you're pulling pretty hard and getting no movement whatsoever, then something might be wrong, but as a rule the majority of these boards are removable - they're not glued or otherwise fastened into position.

If they are the flat ribbons that seem like thin plastic or cardboard, typically they are hard to pull out. The ribbons on the logic board have press snaps, but those on the top boards are just tough to pull out. The key is not to bend them, but apply pressure with your thumb and index near the connector base and pull straight up. Here are some images from my unit:

Top Board Ribbons (Tight ribbon slots)

Lower Controller Boards (All those shiny dark ribbons have pressure snaps, much easier to deal with, but make sure they're secure and tight after you put them back in place)

Touch Screen Not Working. Have cleaned the ribbon cable contacts and still the screen lights up showing the buttons but nothing on the touch pad works. If not the ribbon cable being dirty, I guess i


Most of the time the panel buttons stop working because grease gets between the outer panel and the contacts underneath. Disassemble the door and if you need to carefully peel back the outer panel, use some paper towels to remove the heavy grease, then using a Q-tip and some rubbing alcohol clean the back of the panel and the surface contacts on the board, then re-assemble.

Dp50747 has vertical 2 inch wide black row with a green line up the center, which card might be at fault? thanks


If you have JUST two green lines then your choices are between the buffer boards, YSUS board (all boards on the LEFT side of the TV when looking from the back) and , less likely, the main or plasma controller board. I'd really focus on the first two.

if you have two lines ON TOP of otherwise normal picture then you most likely have a bad panel, specifically the address register ICs embedded in the display's fabric underneath the display ... there's no solution to that I'm afraid.

While watching tv loud pop at rear then tv went off,bits of oily debris on shelf underneath


The fault is with the power supply regulator board. Bursted capacitor. It will be best to replace the power regulator board to plasma TVs, rather than making 'surgery' to it. Contact the authorised service center for LG at your town to purchase a new power retulator board. If you are not handy enough replace it, seek tech assistance.

I have an LG 42PJ350 plasma TV which has suddenly developed a vertical green line around 1.5in wide from top to the bottom of the screen. It makes no difference whether watcing TV or using XBox. Is this...


Yes, life span on Plasma and LCD sets is 3-5 years.

The green line (or any line) can be a board (sustain types on Plasma or inverter on LCD) but can even be a control problem inside the set--area that controls scanning etc) and in worst case can be the display panel itself--fatal issue.

Trouble shooting entails a signal generator, a expensive scope, and a good set of hands working with them to check voltage, waveforms, etc to try to decide where the problem is.

Then we have the board jockeys who guess and try one board after another (gets expensive and takes time) to see which if any board will fix the problem---when all boards have been tried (seen this ) all that is left is the panel or display unit--cost for that is more than the set new.

Black vertical stripe on screen


hello,if the stripe goes completely thru the screen top to bottom,you most likely have a defective plasma panel. Other instances will require substitution of the drive boards(c boards) and rarely the control board.

Picture on plasma screen is very patchy


Hi, you either have a bad Y board or it may actually be adjustable.
Adjusting it would involve opening the back, Most Philips plasma sets use torx 10 screws and a few other sizes on the larger wall mount screws, You will have to lay the set face down on a soft quilt or cushions. Depending on the model some may require a few layers of back be removed. the model with the rear lights is one that requires major disassembly to get access to the Y board. The adjustments are on the Y board left side facing the back , A few tiny controls using a small philips with the TV on, good signal mark the controls position with a sharpy then while watching the picture turn slowly till the picture clears up finding a center postion with the least amount of spots and patches. If unable to adjust it you have either a bad Y board or bad panel (screen) .

Where can I sell a pioneer pdp 5070pu plasma tv for parts?


HI, the best way to do this is to disassemble the set and post all the individual internal parts like the power board and main PCB logic and v boards, on line on a e-bay type of sale forum. this way, you can make more money. if you post the entire plasma screen with the crack as is, you will not get many hits. is will be assumed that it is damage goods.

Breaking this set down and, posting the internal circuitry piece by piece will make you more money in this case. The power supply board will sale for at least 289.00. and the main logic(PCB) will sale for 300 to 350. i would go this route to maximizes your gain.

A NARROW GREEN LINE HAS APPEARED VERTICALLY DOWN THE SCREEN OF MY PLASMA TV


Hi chrishelps,

Your problem is one of 2 things - either the driver board (normally named as one of the "C" boards) has failed for that sector of the panel or your panel is damaged. If the line goes COMPLETELY across, the plasma panel is bad and is no way to repair it short of replacement - they aren't disassemblable and wouldn't recommend doing so anyway...
