LG-lcd-tv-42LE5500, pixel and color mapping defect


http://wp.me/ph3BR-cO

this is able to found if plug in USB dongle of which is stored a HD test pattern, use JPG viewer available with this TV set.

discovered that it is not only problem with 42LE5500, 42LE6500 does also. the sales guy claimed that, my test picture has problem, not caused by TV set, but I have 32LD450 and this for apple to apple comparasion.

another test for 32LD450, the picture is good and no shifting of color mapping. may be software bug of 42LE5500 but who knows if it is defect of panel controller or those COG chips.

42LE5500, arrangement of pixels are B-R-G from left to right, not common found such with PC’s monitor, perhaps special specification. but if look at the shift and no RED or GREEN at rightmost edge, and overlap of color test bar, I think this panel or the controller has problem, software may be.

How to see this defective, use a FULL HD picture (1920×1080) to do this test, rightmost side of LCD screen, if 1 or 2 pixels for color line pattern, for RED-YELLOW-GREEN, it is there, only three white lines.

or wait until your TV station to broadcast test bar signal, you will see the color mapping problem.

I must help my friend to let this 42LE5500 goes.

這是能夠發現,如果插入的USB加密狗的是存儲的高清測試模式,觀眾使用JPG格式這台電視機

發現它不是唯一問題42LE550042LE6500是否也銷售聲稱,我的測試圖片有問題不是由於電視機,但我有32LD450,這為蘋果對蘋果的比較。

另一個測試32LD450,圖片是好的,沒有轉移的顏色映射。可能是軟件缺陷42LE5500但誰知道它是面板控制器或缺損焦爐煤氣芯片。

42LE5500,安排像素BRG在到右,發現這種不常見電腦的顯示器,或許特殊規格但如果看看轉變並沒有最右邊的紅色或綠色的邊緣,重疊顏色測試吧,我覺得這個面板或控制器有問題,軟件可能。

怎麼看這個缺陷,使用的全高清圖片(1920)做這個測試,最右側的液晶屏,如果1或2個像素的彩色線條圖案,黃綠,它的存在,只有三個白線

或者等到你的電視台播放測試條信號會看到顏色的映射問題

我必須幫助我的朋友,讓這個42LE5500
