REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

LG L30W26 - LG L30W36 - LG MW30LZ10 - LG MW30LZ12 - LCD DIRECT VIEW TVs - DISASSEMBLE PROCEDURE


DISASSEMBLY
This model contains many screws. During each level of disassembly, keep the screws separated to ease reassembly. If desired, mark the screws and screw hole with different colored markers while disassembling.
  • Remove the cover and the stand.
  • Remove the back cover.
With the back cover removed, individual circuit boards can be removed. The ballast assemblies can be accessed by removing the shield covering them. To gain access to the lamps, continue with the disassembly, starting with the support assembly. To remove the support assembly, first remove circuit boards that block the assembly's screws.
  • To aid with reassembly, mark each screw and location with a marker to insure they are used in the correct location. Use a different color marker for each level of disassembly.
  • Remove the Speaker and Control panel circuit boards.
  • Remove the Jackpack circuit board.
  • Remove the screws from the NTSC board and lay it over on the Power Supply board (there is no need to disconnect the board). Now, remove the frame and front of the cabinet.
  • Remove the shields from the three remaining circuit boards.
  • Now remove the LCD driver board by removing the cables. There is a latch on each of the female connectors that must be lifted before the cable can be removed.
  • To gain access to the lamps, turn the panel over, remove the screen’s metal frame, and remove the screws holding the plastic frame in place.
  • Once the screws are removed, place the metal frame back onto the screen (do not replace the screws). Turn the assembly over and remove the LCD driver cables from their holders. Then carefully lift the back-light assembly up from the screen.
  • Replace any defective lamps by unplugging the connectors at both ends, release the bulbs from the plastic holders (in the middle of each lamp assembly), and lift them up.
LARGE SCREEN MODELS
The example was made using the 32LX1D. It is very similar to the 26LX1D, 26LX2D, 32LP1D, and 32LX2D.
1) Remove the stand and back cover.
2) Remove the Jack pack trim piece and shield.
3) Remove the main shield.
Now most parts can be accessed.
