CHT9000 --- The first custom-made 3G Smartphone made by HTC was
launched by Chung-Hwa Telecom Taiwan, is the best-seller model which
more than 10,000 units were shipped within 2 months as it launched. The
other family members are all in the same hardware specification as
CHT9000, they are HTC TyTN, HTC Hermes & Dopod 838 Pro.
Unfortunately, it(CHT9000) comes up a severe issue on its touch screen
with a high failure rate. My Dopod 838 Pro got same problem as well
right after 72 hours running. 這支號稱在國內兩個月之內銷售破萬的暢銷熱機 --- CHT9000, 是中華電信的第一支依照市場定位而客製化的智慧型手機, 囊括 WiFi、Bluetooth 等雙無線功能的 3G PDA手機,功能之強大 已堪稱為少數商務機等級當中上選之一,其同型的兄弟機種則有 HTC Hermes, HTC TyTN, 以及甫上市的 Dopod 838Pro, 均以同一硬體規格為基本架構,搭配不同外型、顏色、按鈕配置 以及不同語言等等行銷至世界各地,其擁有之市佔率理當不在少數。 HTC CHT9000 HTC TyTN Dopod 838 pro ![]() ![]() ![]() HTC Hermes: (Picture linked from Engadget.com) ![]() 然而,在國內率先上市的 CHT9000,近來卻頻傳在觸控定位不準確的問題, 狀況嚴重時甚至無法點到右側的下拉bar,使用螢幕小鍵盤常常會點錯字, 手寫輸入時錯誤率也大增,但偶爾心情好時他又會暫時回復正常...... ![]() How to know if your device is in trouble??? 如何得知你的手機出了問題? 1. 進入「記事」編輯模式,以觸控筆自右上畫直線至左下方, 畫線過程請全程注意筆尖與產生線條的差距程度, 本問題點多數發生在螢幕的右側,越往右側外框邊緣移動, 可能產生的差距也就越大。 Start a new "Notes" on your CHT9000 by drawing a straight line from upper left corner to lower right, monitor the gap between the end of the straight line and the location where the stylus tip stops. ![]() 2. 以下範例為「行事曆」的編輯畫面,利用筆尖在螢幕右下方長時間壓按使其跳出小型選單, 在選單蹦出之前會出現一個小圓圈,請注意觀察筆尖壓按處與此小圓圈圓心處的差距。 Or you can tap-and-hold at the lower right corner of the screen in any other editing mode and measure the distance between pen tip and the central location where the circle pop-up before a sub-menu shows. ![]() 3. 當觸控偏移發生以下狀況時,即使點選螢幕右側外框邊緣, 仍無法操作最右側的上下翻頁拉桿。 You won't be able to reach the scroll bar at the right side when touch panel got offset as serious as the picture shown below. ![]() 在日本網站已經有實際的拆機經驗可參考,並且已有解決該觸控不準的方式,參考網址請按此: A Japanese site has announced the CHT9000 hardware issue and solutions prior to my writing, see link below: http://inuchanbt.blog54.fc2.com/blog-entry-99.html 底下圖文為 Larry 親自實作之紀錄,提供各位參考。 請注意: 問題點解決方法: Steps to eliminate touch screen issue: A. 拆解電池背蓋,取下SD卡、SIM卡、電池本體後,卸下後方外殼,拆解機板並鬆開LCD固定螺絲。 ![]() B. 拆解螢幕部分時須注意與之連結的軟排線。 ![]() C. 圖片為LCD部分,問題肇因於螢幕前方外殼內部的海綿襯條,壓迫到觸控螢幕的範圍。 Here it is!!! As the red line shows at the right side of the touch screen, where there was a pressure applied from a sponge strip under the front cover(casing) and made that issue resulted. Idealy, for a LCM (a module combined with LCD and touch panel glass top), the "Touchable" area should equal to the "Viewable" area.( or the "touchable" area can be a little bit wider, it would be acceptable) In this case, the "Touchable" area is much wider so that the front casing may often apply a pressure to touch panel via the sponge strip under the front cover(casing). ![]() D. 撕下前殼右側內部(翻轉後為左側)之海綿襯條。 Remove the sponge strip from the front cover. (Shown as the picture below) PS. A sponge strip applied here as a spacer right between the LCM and front cover. ![]() E. 取下海綿襯條後並清潔完成的外殼內部。 When done, assemble all parts and casing. ![]() F. 組裝回復所有零件以及外殼裝配,建議重新開機後進行一次筆觸定位。 本機原本觸控偏移的頻率甚高,每天需要校正5-6次,自此次處理完成後 至今(已經兩天)未曾在出現過偏移現象,操作精準度均在控制之內。 It is recommended to perform "Screen alignment" once right after restart the device. For my Dopod 838 pro, I used to perform screen alignment more than 5 times a day. Now I am happy on tapping anything accurately after reworking... ![]() ![]() 以上所有圖文均為本站原創,如有轉載引用之需求,煩請來函聯繫告知。 - by Larry |
