lcd panel edid eeprom error m6700 free sample

Hi, I have read of swapping the 17" panel of iMac using an item that basically change the content of the EEPROM of the panel making it disguised for another one.

So, here is the question! I have a couple of panels from iMac G5 20", labeled LM201W01(ST)(B2). My iMac Intel 20" (A1207) uses a panel with exactly the same characteristics! So probably it would be interchangeable if the content of the Extended Display Identification Data (EDID) EEPROM is copied from G5 panel to intel panel.

Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc.5. To be sure that no shock hazard exists, check for leakage current in 0.15 µF the following manner. TEST PROBE• Plug the AC cord directly into a 110-240 volt AC outlet.• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral- leled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduit or elec- trical ground connected to an earth ground. TO EXPOSED CONNECT TO METAL PARTS KNOWN EARTH• Use an AC voltmeter having with 5000 ohm per volt, or higher, sen- GROUND sitivity or measure the AC voltage drop across the resistor.• Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////SAFETY NOTICEMany electrical and mechanical parts in LCD colour television have For continued protection, replacement parts must be identical to thosespecial safety-related characteristics. used in the original circuit.These characteristics are often not evident from visual inspection, nor The use of a substitute replacement parts which do not have the samecan protection afforded by them be necessarily increased by using safety characteristics as the factory recommended replacement partsreplacement components rated for higher voltage, wattage, etc. shown in this service manual, may create shock, fire or other hazards.Replacement parts which have these special safety characteristics areidentified in this manual; electrical components having such featuresare identified by " " and shaded areas in the Replacement Parts Listand Schematic Diagrams.///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

I"m faced with an interesting issue! One of our client Dell laptop does not show POST/Dell splash screen when powered on. Eventually, after a minute or two, the Windows login screen appears. I"ve replaced the LCD panel, updated BIOS, drained power, reseated everything possible, and even re-imaged the HD. Dell diagnostics gives me this error: LCD EDID - Unable to access EDI EEPROM, even after replacing the LCD panel. I"m beginning to suspect that the motherboard is the culprit here. Anyone seen this type of issue before?Just out of curiosity, what does Dell Support have to say about that error?

SOLVED! I replaced the LVDS cable, and I am now able to see the Dell splash screen and also access BIOS and PXE boot. Diagnostics no longer reports an error. It"s a beautiful day - birds are chirping, flowers are blooming, people are happy. Thank you all for the support!!!
