Thx anyhow, yes i followed the flowchart religiously and all the supplies are present (3.3,5,60 and 80).
i disconnected and reconnected and all appeared as it should.

i think it is the pdp and the hiss !

To the tip i think

Sad

Actually it isn't from the pdp, i think it is just the fets firing up, can hear the noise from both the x and y sus pcbs.

Im going to give it a couple more days and read up a bit more.

Just one quickie if anyone knows:

If i remove the sustain boards connections from the psu, should there still be 60v (va) and 80v (vs) across those connections on the psu, using a dvm. I am wondering about there being no load.

BTW I do have those readings 60 and 80v

Better watch it. Not only are you at times talking to yourself, but you are actually referencing your own quotes. Laughing

That always happens to me as i'm walking down the street mumbling. Someone will say 'pardon' and i'll say 'i'm not talking to you'.

Force of habit i'm afraid, in spoken word and in text! Cool

Posting the model and what it's doing or not doing is a good start.

Hi minnie. thx for the reply. Sorry about the lack of info. I did mention the model no' in my second post but it isn't easy to spot. Let me start as i should have.

I have a Sony KE-42TS2E which goes into protection mode a couple of seconds after switch on.

I switch it on, the relay energizes, the screen lights up for a second then shuts down, although the relay doesn't turn off for a further 4 seconds.
The led then blinks twice, pauses 3 seconds then blinks twice again.
It then tries ti 'fire up' again, fails, then stays in standby with the blinking senario above.

I found 4 x 2200uf elec caps on the psu that were bulging, I replaced these but no joy, same problem. Shame as i recently found out that these caps come as arepair kit so must be a common problem?

I am a bit lost now, can't find any references to the sustain pcbs or psu as i guess they may be oem?

Anyway, any help really would be appreciated.
If you need any further info please ask.

Many thx

Jon
