Pioneer lx6090 2 x flashing red light at start up

[kamei10]

Hi since today my pioneer don't start up anymore. When it in standby the red light work and when i power up the tv with the remote control you hear the click as usual but there is no image, the blue led will also not go on but the red standby led flashing 2 times.
Somebody have a clue what is wrong with the screen and is it easy to repair it as i love the screen, hope to get it repair as it is still the best tv i have had.

Nice Tv wait for Tom66 to chime in he will help you out, but if you get stuck DO NOT BIN IT OR SELL IT well worth waiting and spending money it to repair. I think two red blink is a fault on the Ydrive board. You can start by uploading images of the boards inside the Tv please.

Hi, thanks for the fast reply , first i need to get this tv upstairs to put it on a table where it can be for a time for repair as i probably need to order one or more parts and it should be not fixed on one day.

I can buy another lx6090 but i dont know the problem on the screen, but maybe for parts if the panel is faulty.
There is a line on the screen in the left corner at the downside of the screen, should it be a faulty panel or also a problem with some of the cards, search a lot for finding this problem in forums but nothing found from a pioneer with this problem

Normally just a lose connector going to the panel will cause that on the other one Keep us updated.

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

OK i will keep you updated. Have this type also the trap switch or are these switches only in the older types ?

No they dont buddy.

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

I have tried to mesure the values like on this thread https://www.badcaps.net/forum/showthread.php?t=43882
I have opened the back and did the mesures but i didn't mesure anything, you can hear some noise from the psu. When i took out the y drive connecter it still the same, no values and the psu make the same noise.
When i put the power on with the y drive disconnected the red flashed 3 times instead of 2 and also the intern red led (i think on the mainbord)

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

Ok so with Ydrive disconnected you dont get any Vsus at all ? Also these sets when they lock out into an error show a red Led on the mobo and when Ydrive is disconnected from the Psu tv flashes 3 Red because it detects Ydrive isnt plugged in.

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

No, i have no Vsus with the ydrive disconnected, there is only one led on the mobo that will flicker the same times than the red led outside on the front

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

Ok what about when Xdrive is unplugged ? Does it rise for a second ?

[kamei10]

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

Now with both disconnected it doesn't go higher than 20VAC , the same as with both connected but the right power board from the psu where the main voltage is connected to is still making a noise sound when powered up.

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

Ok so with Xdrive it was 0 ? Also plug Ydrive back in and check what it goes too.

[kamei10]

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

I tried again and with the ydrive alone connected it stay at 0 VAC,
With the xdrive alone connected 20 - 25VAC
With both disconnected around 20 - 25 VAC
With both connected stay it at 0V

Maybe is my multimeter not fast enough to read as the other person could read 208V on the points, so should the ydrive assy need to be replaced ?
The numbers on the board are:
ANP-2214-B and AWV2541-D-60F

Should these boards works also from a lx5090 as it is only a stamp on the board with 50 or 60 on

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

Ok before you do, do you know how to check for S/C and does your meter have a diode mode ?

[kamei10]

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

what means S/C , yes multimeter have a diode mode, its a fluke

[ReeceyBurger123]

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

S/C means short circuit, look up on youtube how to test transistors for short circuit might be worth going over the Ydrive and Xdrive testing the big transistors on them they normally fail first.

You need to use Vdc not Vac mode.

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

You need to use Vdc not Vac mode.

OK, i will try again than this evening

[kamei10]

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

I measured now on VDC and have following measurements:
- With Ydrive connected 0V
- With Xdrive connected 210V
- With X and ydrive connected 0V
- Vadr 75VDC

Do i need to discharge something to take out the ydrive plate and for measure the transistors ?
