Has anyone done one ? I forget, but the ones in the fdx or hdx series. I suspect they're all the same.
They were on backorder for quite awhile and we finally got it and the set is fixed and gone, and the money is probably spent, but I was looking at the old one.
There are several SMD caps on the module that check bad and some are not even recognized by the cap checker. Some of these are near two identical ICs that each have two crystals nearby. I reckon these are digital clock"ing" chips and with the symptom I think it may be repairable.
In this particular specimen there appears to be no capacitor piss, or at least the resultant corrosion.
The symptom is that there is constant piecrusting in the main image only, the PIP is good and the OSD is good. It is not a sweep problem. It is because the set does not run 480i even on an NTSC input, and the PIP uses a seperate scan converter for obvious reasons.
The problem used to be only when the set was cold.
Two plus two have at least come up to three here. Thus my plan; a friend has a Toshiba with exactly the same problem, so I made a deal with the shop, I will replace all the bad caps on company time, the only way to see if this worked is for me to go install it in my friend's set. These things are $280 list, so we agreed, if it works I'll bring $100.
Now a question, who owns my buddy's old board which will be abandoned to me ?
I don't have the tools at home anymore to fix it, the boss sold me a board which was a pull, they pulled it, cust didn't want it, it is theirs until I give them money.
I will append this later with more info, and later when I know if the fix worked. I'd like your input, especially if you've fixed one, but I also post this to share the info.
For those of you who want raw data : I found at least 6 marginal capacitors, 3 bad and 2 that weren't even recognized as caps by the checker. The symptom used to go away when warmed up.
