I just repaired a 32"
KV32FV300
Kept coming up on Video 1 and accepting no other Commands.
I replaced S2001 thru S2005(TV/Video,Volume up/down,Channel up/down)
1-692-431-21
WinStips has a couple of ther tips
Replace S1007, S1008 (1-762-816-11). Test This By Removing The Switches
And See If Your Functions Return.
or
This Can Be Caused By The Following:
1. The Menu Switches On The Hu Or Hs Board Could Be Defective.
2. Diode D006 On The A Board Off Of Ic001/Pin 42 (Key Line) Can Also Cause
Miss-Operation Of The Volume Channel Menu Or Tv/Video Function.
3. If Customer Cleans The Crt Screen The Glass Cleaner Can Also Drip On To
The Hu Board Causing Intermittent Or Loss Of Functions. In This Case
Replacing The Hu Or Hs Board And Advice The Customer Not To Allow The
Cleaner To Drip Down The Crt Screen.
4. In Some Cases The Key Buttons On The Hu Or Hs Board Might Not Be
Centered And Causing The Buttons To Touch The Bezel Which Can Cause
Intermittent Miss-Operation. Remove And Switch And Remount Slightly Tilted
Away From The Bezel So The Button No Longer Touches The Bezel. It Is
Believed One Of The Reasons For This Symptom Is Due To:
1. Glass Cleaner Might Be Dripping On To The Hs Or Hu Board Mounted
Underneath The Crt. 2. One Of The Menu Buttons Is Not Centered Causing It
To Be Hitting The Bezel.
3. One Of The Menu Buttons Is Defective
