Re: Pioneer lx6090 2 x flashing red light at start up

Y-drive is shorted then. I'd test across the Y-drive on ohms mode (with it disconnected from the power board) and see what you get to confirm but this seems to indicate that the Y-drive has failed. It's a reasonably common failure (of the few failures this set has.)

Remember to get the 60" board. The 50" board won't work correctly, without significant modifications.

Nice easy fix there You might not need a new board if you know how to change a few IGBTS but up to you.

Re: Pioneer lx6090 2 x flashing red light at start up

I have measured the transistor and i have only find one faulty,
the one of the right near the ANP-2214-B number D2417
Is it possible that this is the only one that is faulty or could there be more, i tested them all and only this one is shorted

Re: Pioneer lx6090 2 x flashing red light at start up

Take it out of circuit and test it again see if its shorted, then throughly test the others buddy. Normally on sus boards its on transistors that fail.

Hang on thats a diode and it has low ohm resistors across it so its probably not failed but still best just to check mate.

Otherwise i will do the board to the local tv shop to test it out, i have not that much electronic knowledge to repair up to components.

What should i do with the other tv with the blue/yellow line in, should it be a easy fix or could it be something else than just a bad connection ? The guy ask 250 euro for the tv.

Is it a Kuro? Blue/yellow line is most likely a panel fault and therefore not repairable. Though that is very rare on Kuro sets.

Re: Pioneer lx6090 2 x flashing red light at start up

The most likely candidates for failure will be the two transistors mounted on each of the three heatsinks on the left hand side of the board (as installed in the TV, looking from the back.) These are the sustain path transistors. There is a big ~220V electrolytic (brown can) capacitor and poly (green) capacitor mounted near each.

Tom its also a lx6090. Here a picture of the line in the other tv. Its around 20cm high and 3 cm wide.
Ok will check the 3 transistors again and thanks guys for that good supporting to find the fault :-)

Definitely panel, avoid (unless you need the parts)
I wouldn't pay more than £50 for that in that state. It would just ultimately get stripped down...

Re: Pioneer lx6090 2 x flashing red light at start up

Checked the 6 transistors once again but these are ok, all have the same values, the only one that was different is that one on the left corner on the picture, that measures on the 3 pins short and the multimeter kept bieping while measured the others only a small biep or nothing when measured in other direction

Re: Pioneer lx6090 2 x flashing red light at start up

Tom I had a panny with a small line out like that was a 3d one very nice Tv was told its not fixable was just a lose ribbon going to that part of the PDP. But still dont pay more than €50 for it as not worth the risk.

Take it out of circuit and test it then just to be sure.

Re: Pioneer lx6090 2 x flashing red light at start up

Whats the best way to remove it ? A hot air station ?

[ReeceyBurger123]

Re: Pioneer lx6090 2 x flashing red light at start up

Yes, put it on about 380d then low speed setting heat for a little while then pick it up with some pliyers.

Re: Pioneer lx6090 2 x flashing red light at start up

OK, than i need to take it with me to my work, have one at my work available, i keep you informed and once again thanks for all the advice.

Re: Pioneer lx6090 2 x flashing red light at start up

No worries glad to help one awesome Tv well worth saving it

That could be the case if the bar was as wide as one of the driver chips but the drivers cover 1/16th of the panel each, and this line is much smaller, so most likely it is a panel fault.
It is possible it is not, but in my opinion, not a great risk to take.

Re: Pioneer lx6090 2 x flashing red light at start up

I have gone with the circuit board to the local tv shop and the expert measured the board and told me what i thought that was wrong, the transistor near the ANP2214 text in the corner.
Where can i find a replacement for this ? The text on it is 05165.

Re: Pioneer lx6090 2 x flashing red light at start up

Have you took it out of circuit first ?
