REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

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.

PHILIPS 40PFL9401 , SANYO FW40D36F- 40 INCH LCD TV CHASSIS PL15-01 SERVICE MODE, SOFTARE UPDATE SERVICE ADJUSTMENTS

TYPE A

40PFL4901/F7 PHILIPS (Serial No.: ME4)
40PFL4901/F8 PHILIPS (Serial No.: XA1)
40PFL4911/F8 PHILIPS (Serial No.: XA1)
TYPE B

The LCD panel is manufactured to provide many years of useful life.
Occasionally a few non active pixels may appear as a tiny spec of color.
This is not to be considered a defect in the LCD screen.
How to Remove / Install Flat Pack-IC
With Hot-Air Flat Pack-IC De=soldering Machine
1. Prepare the hot-air flat pack-IC de-soldering machine, then apply hot air to the Flat Pack-IC (about 5 to 6 seconds).
2. Remove the flat pack-IC with tweezers while applying the hot air.
3. Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted).
4. Release the flat pack-IC from the CBA using tweezers.
The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC de-soldering machine, whose shape matches that of the Flat Pack-IC.
2. Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage.
3. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when removing it.
With Soldering Iron
1. Using de=soldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily.
2. Lift each lead of the flat pack-IC upward one by one, using a sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot air de=soldering machine.
3. Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted).
4. Release the flat pack-IC from the CBA using tweezers.
With Iron Wire
1. Using de=soldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily.
2. Affix the wire to a workbench or solid mounting point.
3. While heating the pins using a fine tip soldering iron or hot air blower, pull up the wire as the solder melts so as to lift the IC leads from the CBA contact pads.
4. Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted).
5. Release the flat pack-IC from the CBA using tweezers.
Note: When using a soldering iron, care must be taken to ensure that the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle it gently because it may be damaged if force is applied.
Installation
1. Using de-soldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily.
2. The “I” mark on the flat pack-IC indicates pin 1.  Be sure this mark matches the
pin 1 on the PCB when positioning for installation.  Then pre-solder the four corners of the flat pack-IC.
3. Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges.
Disassembly Flowchart
The disassembly steps for the cabinet parts and the CBA in order to gain access to items to be serviced. When reassembling, follow the steps in reverse order. Bend, route and dress the cables as they were.
(1) Order of steps in procedure. When reassembling, follow the steps in reverse order. These numbers are also used as the Identification (location).
(2) Parts to be removed or installed.
(3) Fig. No. showing procedure of part location
(4) Identification of parts to be removed, unhooked, unlocked, released, unplugged, unclamped, or desoldered.
P = Spring, L = Locking Tab, S = Screw,
