It is not the power supply or capacitors if it stays running.
Flickering is caused by a chip on the controller board that is loosening up fro heat.
I have repaired 8 of these
Search bammbammfran or xhd3000 on ebay.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I have an ASUS model X83V and my screen has been flickering (not in brightness, but actually going fuzzy and "jumping"). The flicker can take upwards of 1 hour or more before it goes away, but usually...


my son has this same machine and after a year of almost daily use it developed this same flicker you describe, about every 4 secs, then it got much worse, almost like an old tv rolling. i took it all apart and inspected it all. didn't see anything really troubling.

yesterday it worked fine all day while i installed a bunch of updates for another problem. i left it on all night doing some other things. this morn when i got up it was still ok. then after a while it started in again, every 4 secs.

so i've been troubleshooting the damn thing all evening and have come to the conclusion its from over heating, probably cause of the crappy heat sink connection. i noticed if i take it outside in 40 degree weather and leave it a couple mins on the hood of my truck, it goes away. bring it back in and after 5 mins it comes back. take it back out and its fine again in a few mins. also, yesterday my house as much cooler. my fire was out and it was in the upper 60's in here, today as soon as it got to 76 in here, and it was above that all day, it started acting up

so i think my next step will be to try and make a better union between the chips and the heat sink itself. you should try a test with yours. start it up, make sure its flickering, put it in a cold space for a few mins. just be caustious of condensation.

32" 32lc7d after a few minutes, flickers, then goes dark.


There are no fans in this model but it looks like either the backlights in the screen are breaking down after they have warmed up or a problem in the inverter board, again part of the driver circuit breaking down after a period of time. They inverter boards can sometimes be replaced seperatly but usually come with a new screen which if the backlights are at fault then the screen would need to be replaced.

Sony KP75HW40 unstable red. (not the usual problem)


I would suggest either the Focus block or the RED CRT drive board either one of those items could cause the symptom. A defective CRT could also, but a shorted CRT doesnt usually go back to being normal

Screen seems to dim and there is flickering while watching


This is both a common and fairly easy repair in this unit. Remove the back, but not all of the back needs to be removed to access the power supply area and locate the power supply board. You might find that all three E919,E920,E921 of the 35v/680uf caps in the upper left of the PS board are bowed and/or vented. Replace all three of them even if they test good...
Next, esr the remaining caps. Last one we did here in the shop there were 16 total that we replaced, many were orange in color but I don't have any notes on their value. The orange color of the cap is a lesser temp range we used 105 degree or better as replacements. Some we used a higher rated cap (higher voltage) same uf rating. Gave it a greater reliability.
Good Luck!
