[TechAssist] Re: Help! - Sony KV32S45 TV

Dan,
When you feed the video in on the S-video jack, you are bypassing the comb
filter.
So the Comb filter needs to be replaced. I think the one you need is on the
back jack panel, but I'm not sure.
Some models have "two" comb filters in them. The part number I have is
1-467-554-21.
*Check with Fulton Radio (1- 800-248-0898 ). They can comfirm the right part
number for your model.
If your comb filter is on the "B" board, you may want to replace the
complete board wich is part # A1135950A.

Good luck,
LLW

>>Dan,
>>Here are three tips I found for similar problems on different (KV32S)
>>models.
>>Not sure if they apply to your model.
>>
>>1. Feed video in on the S-Video jack. If it shows a good picture, then the
>>Comb filter is bad. Might be labeled CM401 on the video input board. Look
>>for a black square part (1" x 1/2 " aprox.)
>>
>>2. Check C3501 (47 @ 25) on thhe "B" board behind the tuner.
>>
>>3. Check C1266 (47 @ 16), next to comb filter.
>>
>>  If these tips do not help, then answer this question, cause there are a
>>couple more tips, that I can send you.
>>Question: Does the timer light flash continously ?

>>HTH,
