Re: Xerox xa7-19i - ao4620 failed

I dismantled the screen today and got the bulbs out. Connected them to the inverter and plugged everything on. Indeed the bottom 2 bulbs are pink, the upper 2 are not pink but do not light up completely, on the left i think 5 cm no light at all. All separates bulbs are black on the sides. I checked for replacements, but will cost around 20 euro. I figured it is pointless to go on and repair this screen, for 50 euros I can get a new one. I through it away, but I left the inverter board. If enyone needs it let me know and I will send it to ya for...

Thank you, all right sorry for posting pictures off-site. I have also checked the board very thoroughly and haven't been able to find any faulty components visually.

I ordered the right value capacitors and will change them later when they arrive.
I will check the transformers. Can I test everything with the LCD panel disconnected?

I will check the bulb as well, whether it is pink or not. If it is pink, the only way to fix it is to replace it?

Thanks

Thank you very much.
I made a few pictures and uploaded on photobucket. Is this ok or is this exactly what offsite means and should not be done, forgive me than.

I have some background in electronics. I have been building mostly guitar pre amplifiers past few years. I also repaired various tube and transistor amplifiers.
I once fixed an LCD screen by replacing the capasitors.
I have a good soldering Iron and my soldering skills are beyond average. I also own an oscilloscope, however I have no clue ho to use...

Re: Xerox xa7-19i - ao4620 failed

Hello, this is an old thread however I hope to get some replies.
I have the same Xerox monitor with 2 issues.

First of all, the monitor goes black after around 3 seconds when I put it on. The same problem as I read all over the internet.
The second problem is, when it is on the colors are not right, it is all red(ish).

I opened it up and did a visual check. Nothing is burned visually. I also replaced the capacitors. Mine has 2 x 470uF and 4 x 680uf, but I replaced all of them with 6 x 470uF.
