Ok cheers will try and measure later however when I switch on the TV I get these small green LEDs appear on each board then they gradually get fainter then disappear is this normal?

The SC board will be to the left hand side looking at it from the rear?

not for a working tv, when they go faint, usually the TV has shutdown and the voltage bleeds off.

Any ideas what to check to see if it's getting voltage to the right places?

? what's the current status of the TV? Is it still intermittent 7 blink? will it stay on?

Pity, was hoping she'd still fire up. Only thing i can think of is to see if the SC board on its own is triggering SOS7.

I've taken this out of a HD 2008 guide.page 15. Should still be able to be applied to this as I see no SC50 jumper connector the later boards have 2009 on to do the same test.

Disconnect connectors SC41/SU41, SC42/SD42, SC46/SD46,

jumper between “VF Ground” (labeled H.V. DANGER) on the SU board or SD board and coil L801 on the SC board,


Power on and see if SOS7 or normal startup with no SOS

Hmm time to re-start this thread, Not done anything with the TV since last year and managed to get a working&tested SC board for £8 hopefully should clear the fault,

Looks like I've dropped a clanger and ordered the SC board for the TH-42PZ80B instead of the TH-42PZ80BA the correct board I should have ordered was the TNP A4657 instead I've got the TNP A4410 both look very similar and have the same mounting positions/pins and cable/ribbon connections would gthis work or not worth the gamble?

I believe they're compatible - one is a cost-down version of the other.

Cheers will give it a go, As I've now wired it back up without trying the new board the TV comes on to a red light then will power up using the remote but screen is black/no picture green light blinks very rapidly when you use the remote

Check LVDS cable is fully seated.

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

Which one is that?

[tom66]

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

Runs between A & D boards, it's a red one, multi wires very thin and delicate.

[DavyMac]

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

Is this it?

[tom66]

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

That's the one.

Swapped the lead out with the other I had then started getting the 6 red lights flashing swapped the old D board and lead back across and still getting 6 red lights flashing

[tom66]

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

Check white ribbon to SC & power to SC are properly connected. 6 blinks is SOS6 (SC Energy Recovery) and could be bad SC board. Does LED on SC glow?

Re: Panasonic 42" plasma screen TH-42PZ82BA cheap fix?

Finally swapped over the SC board for another which I'd picked up now the problem is the green light blinks loads then comes on but TV won't power up/fans dont kick in any ideas?
