SOURCE: LG 42PX4MVH PLASMA TV - Sound but no picture.

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.

The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

I think there might be 5 screws. But it should just pull out after you remove them. Check the diagram on page 13 of the USER'S MANUAL at the following link and post back on how you make out.

Normally though you remove the base BEFORE mounting on the wall.

SOURCE: I would like to remove the pedestal or stand from a LG 42LG70 TV because I want to place the TV on a wall mount.

Usually the safe way to do this is look first at the owner manual but lay set face down on a padded surface so all weight is on the frame around the screen and no weight on the screen itself, exert no downward pressure in that position or screen may be damaged.

Usually pedestal is secured by 4 or more screws that may require the back cover of the set to be removed first, to get at---a careful look with it face down will show if part of the pedestal is under the rear cover of the set or not.

How to replace a control board on a philips rear projection tv

This is really easy how it happens but 75 screws take time. You will have to first unplug the tv and hold the power button on for about a minute to drain all current form the TV. You will never forget the shock if you live through it. Once the power is drained locate you board. It should be held on by about 6 screws and might be partially blocked by another component that has to be removed first. The connectors on the board are usually clip ons so be careful when removing not to break the locking tabs. Remove the board, replace and you are ready to go.

I can't remove the stand off the tv

Hi, i have instruction on removing your base stand.

Removing the Pedestal Stand
1) Carefully lay the front of the unit face down on a flat,
cushioned surface such as a quilt or blanket. Leave the stand
protruding over the edge of the surface.
Note: Extreme care should always be used when removing
the pedestal stand to avoid damage to the LCD panel.
2) Remove the jack pack cover on the back of the TV to expose
the pedestal stand screws. The jack pack cover can be removed
without tools.
3) Remove the four screws shown in the diagram below. This will
allow removal of the pedestal stand.
4) Once you have removed all four screws holding the pedestal
stand in place, remove the pedestal stand from the TV by
sliding the pedestal stand away from the TV.

Red light blinking and no response akai LCT2715

The led is blinking due to fault in power supply board.
On the power supply board there are some capacitors and ICs .if any of those gets short or faulty the power supply board will create problems and the red light will start blinking. The components on the board needs to be checked with the help of multimeter and continuity tester.And the faulty components needs to be replaced with the help of soldering iron. the procedure to check the power supply board is as follows:---- 1) You are going to need a Phillips ( X ) Screwdriver for this procedure. The first thing you will want to do is find a suitable location to disassemble the TV. Try to find somewhere with plenty of space to work and preferably somewhere you will not have any hazards such as static (like carpet)
Lay the TV Flat on its face (picture side down) and remove the 4 screws from the back of the TV holding the base on.
Next you will want to process to remove the screws around the back cover. There are 12 screws you will need to remove (refer to picture for locations).
Carefully remove the back panel of the TV. It may snag on the coaxial connector so be careful.

2) Once you have the back off of the TV you can see the Main board and power supply covers.You will now need to remove the left (right side from the back) speaker cover to allow access to two of the screws holding the Power Supply Cover in place. This is easy and pretty straight forward and has 8 screws around the perimeter.
Once you have the speaker cover off you should be able to access the screws on the side and you will also want to remove the other screws from around the sides of the cover. Some TV's I have worked on only had 6 where others had 7 or 8. Just make sure to remove all of the screws before trying to remove the cover.
Once you have the cover removed you will see the Power supply. Remove the wiring harnesses from the power supply board. You will have 4 cables at the top of the power supply and one main power input at the bottom. The main power input may have some glue securing it in place. Simply cut this with a knife or pull it loose.
Once you have the cables off of the power supply you can remove it from the TV via the screws on the 4 corners. Be careful not to damage anything as you remove these screws. You now have the Power Supply removed from the TV.
you can now get the power supply repaired from any local tv repair technician.or get new replacement power supply from the service center.or from online stores like : or from
Thanks. you can rate this solution and show your appreciation.

My buttons aren't working

You have a bad control board most likely. You can replace it yourself if your handy or just have a repairman come and do it.
To do it yourself get the new part from an appliance parts shop using the machine's model number. They should be able to look up the correct part for you. You'll need to open up the whole microwave by removing the top casing. This is usually held on by a couple of screws on the sides or bottom of the machine. Once you have that off, just unscrew the old control board and start moving the wires over one at a time from the old board to the new one, making sure to put them in the exact same spots. Once its all replaced just put everything back together opposite the way you took it apart, plug it in and give it a go. Hope this helps.

How to fix my lg screen is only half viewable. the visable area is 50% and only on the right side. thanks

The problem is in the right (viewed from the back of the panel) X- Drive Board (A-Board). Replace it. Model number is needed for the part number of the board.
Before servicing your unit, touch your fingers repeatedly to a ground connection point or unpainted metal in the product. Before removing a replacement part from its package, touch the anti-static bag to a ground connection point or unpainted metal in the product. Handle the electronic control assembly by its edges only
  1. Remove the back cover by removing the screws holding it.
    (The Stand does not need to be removed).
  2. moz-screenshot.pngThe right X-Board is located at the bottom part of the TV beneath a heat sink. moz-screenshot-2.png
  3. Disconnect Main Board connectors.
  4. moz-screenshot-1.pngRemove the Main Board by removing the screws holding it.
  5. Remove the screws holding the heat sink of the X Drive Boards in place. Rock back and slide down to remove.
  6. Disconnect Right X Drive Board connectors. Take extra care not to damage the locks and TCP films. They can be easily damaged.
  7. Remove the screws holding the Right X Drive Board in place.
  8. Remove the Right X Drive Board.
  9. Replace the defective Right X Drive board and reassemble the unit in reverse order.

No picture just a clicking sound. TV wont turn of. I have to unplug tv to get clicking to stop. TV is less than 1yr old. TV is Samsung LN46 A550

I just fixed this problem myself on my TV by buying a power board from
It was $136 including 3 day Fedex.
It really was easy. Unplug from power. Remove 4 big screws, about 10 smaller screws, then 6 screws on the power board once you take the back off. There are about 6 clips on the board to undo too. Take a picture when you open the back for good measure.
It took me less than 1hr.
No affiliation with the website. I instant messaged with a tech 1st, they reinforced the research I had already done.

Toshiba 42" suddenly has blue arc projecting through lower half of screen. Confirmed it was the blue tube by removing the projector lens and looking at the direct image.  Is this a bad tube or something...


This is not a bad tube it is a convergence problem. Your convergence amplifiers are malfunctioning, and need to be replaced. If you have a background in electronics, you can remove the back of the TV locate the Convergence ICs (using the schematic or service manual) and the order the parts you will need which are the two convergence ICs and the biasing resistors (you will see these on the schematic). To remove them unsolder the pins, unscrew the screws holding them on the heat sink and remove them carefully, if they stick use a solvent to break down the adhesion of the heat sink paste. Once loose, take them out and then unsolder the biasing resistors and replace them with the ones you ordered along with the ICs.

To install the new ICs put heat sink paste on the back of the ICs and insert the pins into the proper holes in the circuit board. Screw the screws back in securely, and solder the connections back.

After doing this you will need to perform a convergence adjustment, using the cross hair adjustment screen (access this from your TV menu). and the you will need to do an advance adjustment using the crosshatch pattern (also accessed from your TV menu).

Once these are done use you service manual to follow the procedures on locking the adjustments into the TVs memory.

I hope this helps,

Thank you,

Replacing ic's of TP50H95

I can try and guide you from my very limited experience if you'd like.
When at the back of the set looking into the tv, the board that is furtherest to your left and has a riser ontop of it is the board that contains the two stk392's. Look for the side by side aluminium heat dissipaters that the stk392's are attached to (you can't see the stk392's from the back of the set, the dissipaters are in the way) You need to get that board out to complete repair, once you remove the board, the solder points for both the dissipaters and the stk392's are obvious.
I took a photo of all the connections prior to removing board and then labeled all of them. Once I replaced the stk's, I was surprised how easy it was to get it all back together, I didn't need the photo and my repair was successful. There were about 25 different connections and 8 or so screws holding the board in place including one or two in the middle. I hope this helps. Good luck.

I need some more info on the backlight capacitors problem

Warning: this method is not guaranteed to work, and performing it can damage your inverter board. I can't find the post from the guy who actually came up with this solution but it requires soldering in an LED, so here's what I did:
- You need to disassemble the TV to get to the large inverter board on the right side (when viewed from the back). This is a cumbersome process, requires removing all of the plastic housing screws (the speaker grill covers can be pulled off to reveal the screws on the front side), removing the power supply cover and power brick, removing the component connector module, removing the TV tuner module, removing the plastic housing (be careful to remove the power switch circuit on the bottom and the TV control circuit on top), removing the motherboard shield, disconnecting the LCD controller harness in the smaller opening towards the bottom, disconnecting the speakers, detaching the power lines to the inverter board (under the foil shield), then removing the screws on the front side of the LCD panel so that you can pull the shield off.. Do not remove the inverter board.
- On the inverter board there is a 20-pin IC near the power connectors, middle of the left side of the board. Pin 1 is the top pin on the left side of the circuit (small indentation in the carrier), pin 10 is the bottom on the same side.
- I bought a 1.8V red LED from Radio Shack. The hot lead is the longer one, you will need to bend the end of it so that it will hook underneath pin 10 on the IC without touching pin 9. Hook the pin and apply a little solder to secure it.
- Bend the LED leads so that you can ground the free lead to the shield when you put the screw back in. Make sure that you don't let either lead touch any other parts of the circuitry, a little electrical tape should protect things but the leads are stiff enough that if you bend them nicely you can avoid any problems.
- You will then have to partially reassemble everything so that you can connect the power brick and the component and tuner modules. Fire the TV up, you should get a blue screen. If it still only flashes you may have put the LED in backwards, or there is some other problem with the inverter or television.
- Reassemble the TV and enjoy.

On the bottom of the machine is the base plate, remove it. You will see a black box (the transformer) that needs to be dismantled. Once inside you will see 2 fuses, one will be blown.
Replace the blown fuse, do not remove both fuses at the same time and get them confused.I bought replacements at Radio Shack. Good Luck
