[操作疑難] Sony Bravia KDL-42W670A 畫面閃動

有無Sony師傅或師兄可以幫我解決一個問題?
我有部42吋 LED 電視機,依家每隔幾秘就閃一次,主要集中在上半部,閃幾下之後就全畫面閃一次!
我估應該唔係Panel及Backlight問題,只剩下主板。
請問邊個有經驗可與我分享!

以下係我部電視出問題的短片:

應該係電源板問題, 電容乾塘機會最大.

P.S. 呢部唔係LED TV !  只係用LED backlight 嘅LCD TV.
        唔好學Samsung咁呃人 !

你可能唔知呢部機係咩料,呢部機無內置牛,係用外置類似Notebook火牛,所以電容問題不存在!
你講嘅"呢部唔係LED TV !只係用LED backlight 嘅LCD TV."我唔係好明你意思!依家賣嘅LED TV都係用LED做backlight嘅LCD TV!

用外置牛就簡單啦, 先換牛試下先啦.

依家開始有賣真嘅LED TV, 用LED做backlight唔可以叫LED TV, 違反商品說明條例 !

如果用LED做backlight可以叫LED TV, 咁我部大肚腩CRT TV都可以叫LED TV啦, 因為有粒LED 電源燈.

你隻外置牛入面都有電容.... 有冇CHECK 過隻外置牛??
依家呢類外置牛多數係行緊單一電壓供電比電視...., 如12V 或19V 之類
入到你部SONY 都仲有降壓電路.. 降壓到5V 3.3V 之類...降壓之後到會有輸出電容....

如果你可以做到... 電容問題不存在  你可以拿好多國際獎了

LCD television uses liquid crystals that turn on and off to build an image across the screen. The crystals don't emit any light themselves so they need a light source behind the LCD panel. The light source has been fluorescent until recently, but newer models are introducing LED lighting as an alternative to fluorescent.

A true LED television uses the LEDs to generate the picture directly. For each pixel, a red, a green and a blue LED are needed. Unlike an LCD television, each LED generates its own illumination so there is no additional light source needed.

Sorry, 佔用了jayeung ching 的查詢帖子。

謝 kamcm ching 資訊!如依所解釋,不知那一部是TRUE LED Television 呢?因前帖有"依家開始有賣真嘅LED TV" ,所以有此一問。

Plasma TV 可能是"差不多"原理,但一定不是LED TV (差天共地!)。期待TRUE LED TV,希望質素有噤上下,又薄又省電!
