A 26 inch will almost certainly be brand engineered, not a Panasonic
design. I think the Viera, in the service manual name quoted,
represents the real manufacturer.

Viera is Panasonic's name for its interconnection with externals

The name I was trying to remember was Vestel.

Viera is Panasonic's TV brand, like 'Sony Trinitron' back in the day.

Looking at the schematic I posted, the parts look solidly Japanese. The main
controller IC is a Panasonic (GenX8). So in this case it seems to be a
Panasonic original.

I haven't looked at it in total darkness, but there's *some* light on
the screen. There is sometimes a lighter black flicker, often associated
with a relay click.

I'm aware, of course, that - when it's working normally - you need to
hold down the ON button on the remote until the light goes to flashing
green and then solid green. But the odd thing under this fault condition
is that, when I turn it on with the switch on the side of the set, the
red standby light comes on for a few seconds and then starts flashing
green without me touching the remote. It then doesn't respond to
*anything* on the remote so I can't turn it back to standby. [I'm
satisfied that the remote is working because I can see red flashes when
pointing my phone camera at it].

As ibn Virgins? As fare as I know most makers use off the shelf bits, but
since Panasonic recent designs all have talking software, I suspect that
this must be developed in house.

Searching for "panasonic tv flashing green led" brings up lots of
information, some more useful than others. Some claim that there is a
code in the number of flashes from the power LED that will help to
diagnose the problem.

Indeed. But holding V- and pressing 0 (zero) on the remote 3 times
*does* do something.

It brings up a line of text on the screen saying "Start Adjustment Menu"
- whatever that means. I can't then get it to do anything else but at
least the screen can't be entirely dead.

I had one did something like that from new. got it replaced. Is it in

While this wouldn't explain why the TV would halt mid task, have you considered
the possibility there is a fault with the remote ?

" Strangely, my remote stopped working today as well. Mine was just unresponsive all
of a sudden. I looked online, and the solution I found was to take the batteries out,

That sounds optimistic.

I have not been through the whole of this thread but have you googled
for a service manual. I know this is not the precise model that you own
but it may offer some starter suggestions.

https://www.manualslib.com/manual/1905110/Panasonic-Tx-40ds500b.html?page=2#manual

It did refer to the keys you used on your remote so it might not be too
different for the next step.

That does not really seem to fit the evidence though...

Roger mentioned that he could see a change in the screen brightness.

Also there is no audio. If it were just a backlight failure, you might
expect other TV functions to still work, and you would possibly be able
to still see an image on screen when you shine a bright torch on it.

IME Traditional LCDs with CFL backlight will normally keep running even
if the inverter driving the backlight has failed. (More modern LED
backlit ones will often cause the PSU to shutdown altogether if one of
the backlight LEDs fails short).

I too suspect the PSU board is the first thing to investigate. Quite
often the output connector will have a silkscreen on the board with the
expected voltages, so that can be an easy test.

Testing for ~700V on the output of the backlight inverter is also
possible, but from the description it sounds like that is probably
working ok.

Thanks for the suggestion, but I'm pretty sure it's not that. I can see
that the remote is sending something by pointing it at my phone's camera.

But when the set is stitched on, the power light goes from red to
flashing green without using the remote. It shouldn't do that!

Yes, I've downloaded the correct service manual - but it seems to assume
that the OSD is working - which it ain't, apart from this single line of
text "Start Adjustment Menu"

In the absense of any obvious other thing, the Power Supply is always the
first thing to check. A lesson from over 50 years ago - and it's stood me
in good stead.

Does the set have a usable video output - something that could be looked

I like our albeit humble telly so when it went bang I took a board out
and sent it to a guy on ebay, paid about 30 quid and it's been fine
since. If you're interested i'll look at my history and see where it went.

Mine is a Toshiba, it does do that, then the light goes solid green and it starts. Despite software updates, the set still gets stuck from time to time with a blank screen and the green light flashing, resolved by power cycling.

'Fraid not. When the Start Adjustment Menu disappears, the screen goes
black rather than grey, and doesn't respond to 2 or mute being pressed.

Sadly no. That seems to be for a plasma set anyway, but I can't get any
actual menu to appear after the Start Adjustment Menu heading.

Do you mean via Scart or HDMI etc.? It does potentially have these but I
wouldn't expect to see anything on them because it hasn't properly got
past the power on stage.

Same for my Toshiba branded Vestel.

(Maybe it it is something to do with global warming as the weather app
reports hypersonic winds and extreme barometric pressures :-).)
