Have a Benq FP92E (Q9CS) inverter board 4H.L2T02.A00 that is missing c703, c704, c707, c708. Wondering if anyone knows what uF and Volts these need to be....Thanks..

Re: Benq FP92E Capacitor specs Help!!
If they weren't ever fitted - and inspection on the solder side should tell you - then you don't need them, end of story.
Sometimes the same board is used in different products with a different "build".
And sometimes it is as simple as the board layout not being changed after the manufacturers discovered those extra bits allowed for by the designer aren't actually required. It's called the beancounter effect. "If it ain't needed, leave it out." and also "why change the board layout just because we are leaving bits OUT?".Friends don't let friends buy Samsung .... -
Re: Benq FP92E Capacitor specs Help!!
No there not empty slot you can still see the solder left over on the back of the board and holes..
I found a schematic for a FP71e (i think that was the model) where a lot of the circuit components match up. Go buy that it looks like c703 and c704 are 470uf 35v and c707 and c708 are 1000uf 16v..
Going to give it a try tonight or tomorrow morning i'll post the results. Whats the worst that could happen it's not working right now...ThanksComment

Re: Benq FP92E Capacitor specs Help!!
HI,
I have a board 4H L2T02.A03 from a Benq T721 who don't work. On my board C708 and C707 are 1000uF 16V, C703 and C704 are 470uF 35V.
I want to replace the board. Do you know where i can find it ?
Merci !Last edited by Bilbao; 11-19-2010, 02:39 PM.Comment

Re: Benq FP92E Capacitor specs Help!!
My standard description on how to post pictures ...
1) Post clear focused pictures of your particular boards AFTER reading
https://www.badcaps.net/forum/showthread.php?t=1868
2) Please do not post pictures inline as they slow down the loading of pages.
3) For best picture quality and clarity take your boards to a window on a sunny day, turn flash off, and use macro mode. Take a top down view of all your boards (front and back). Make sure the photo is legible so that we can read the PCB printing clearly. A shutter speed of 1/125 or faster will produce nice clear focused pictures. Try to get a photo that is 2000x2000 resolution or as close as possible.
4) Here is an example of the pictures we want.
https://www.badcaps.net/forum/showpo...94&postcount=1
5) Also, start a new thread with the pictures requested since you have a different monitor so we don't get confused.--- begin sig file ---
If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.
We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.
Please do not post inline and offsite as they slow down the loading of pages.

Re: Benq FP92E Capacitor specs Help!!
Please, can someone tell, what type is IC601 on that board? It have been blow off because C605 have leak and start the damage of other components.
If you have the same board on hand, please can you send the type of ic direct to mail: md.maxx@kolumbus.fi too.
p.s sorry my bad english, im from Finland
Also i'm interesting if you know or have working ic or know where to buy it.Last edited by MdMaxx; 01-08-2011, 12:25 AM.Comment

Re: Benq FP92E Capacitor specs Help!!
I have a similar board and and ic601 is a 1203p60 8 pin dip.Comment

Re: Benq FP92E Capacitor specs Help!!
Monitor Benq Q7C5 with same "4H L2T02.A03" works fine but after a few minutes (not seconds) momnitor goes off.
You can put it back on and then after a little again switches off.
Tested 8 big capacitors (2x 1000uF/16V 2x 470uF and 2x 1000uF/10V), soldering it out and measured ESR and capacitance, both are ok.
Hard to find without schema.
Anybody idea's or schema?Last edited by hifihifi; 10-26-2012, 01:10 PM.Comment

Hello everyone,
I've got a Benq power board of a XL2540K monitor which suffered from a power cut and is since defective / won't turn on. It's got obvious defects, some blown resistors, some burning around the drain pin of a MOSFET...
... and some 6-pin IC I struggle identifying, that is driving said MOSFET.
The IC is labeled as IC601, so someone with a circuit schematic could probably identify it really quick, unfortunately I can't find the schematics.
In other power boards of Benq for which I did find the schematics, IC601 is an 8-pin NCP1200 PWM controller - I suppose... -
Hi All.
Does anyone have any reference materials or something I can use to try troubleshooting a BenQ TH681? Google unfortunately has turned up zip. I did find a service manual for a W series BenQ but that is pretty much useless, it's more a glorified user manual. A list of voltages would be great as I suspect my mainboard is faulty, the colour wheel voltage is not dipping like it should.
The one I am troubleshooting now was originally overheating after a lamp replacement. It originally would take 2 minutes or so for it to shut off and blink the temp and lamp lights... -
Hi!
I am new to this site, and found it via LLM ChatGPT.
I got a BenQ Ex3501R monitor which i have had for a while now, it works pretty good until recently, it struggles to turn on, i can see the purple welcome screen is shown for a brief time before it vanish again, usually it stays on for a couple of seconds before the main computer screen is shown, but image is still kept black, before i just had to turn it off and on a few times and that would leave it on, but now it takes ever longer to stabilize the image on the screen, ocasionally i can see the computer desktop...01-24-2025, 08:49 PM
