On my FP737s-D the circut board had the part no DS1107A.
Q759 had a black mark on the top of the pcb. Some plastic had 'blown' out of the trannie. Underneath the solder was dry jointed - ie melted. Replaced 759, 760.
Symptom. No screen picture, but a faint squeal noise

Robert,
What happens exactly?
Does power LED flash on/off or the displat comes on and goes off?Do you get Benq screen when you power on with front power switch?
T751,752,753,753 are the transformers to be resoldered ,and resolder Transistors Q759,60,39,40,43,51.
Please check them with a multimeter if you are adept .
Please rate the solution and provide feedback.

My 23" Apple cinema display (2002) has black screen and code flashes three short flashes. How do I find out if the monitor is dead or the power supply?


The only way to test is to use a known working power supply or known working cinema display with the parts you already have.

The view sonic VA1701WB display is totally white on the screen during up the computer and i check the CPU is booting up but at the same time monitor screen is totally white please reply the reason.


It can be due to:
Dead T-CON board on the LCD panel assembly due to blown fuse or just dead board.
Dead power supply on the logic board that supplys the power to the T-CON board.

When starting computer in the morning, the monitor display flashes analog then digital then back to analog and goes blank. Power to the monitor is on. Multiple on/off of power brings display back.


Hi, 12fixlouie here. LCD monitor may have intermittant solder joint on power supply board inside unit. May only need you to resolder it to fix. Locating it is a whole other problem in itself!!! If not into monitor "teardown" and all the other stuff that you will need to attempt a repair, then let me know right away. 12fixlouie

The monitor led is green but it gives white flash and still blank


Check the volatage regulator in the mainboard resolder all you found dried unsolder parts inside mainboard. Voltage test the regulator IC if have a voltage flow 2.5 to 5v DC. check ribbon cable connector from mainboard to controller board if properly connected. In the controller board find the small fuse test it for open.
Reminder:
When you voltage test in the power board
in the primary section of power supply
use hot ground. Do not use the hot ground
when you voltage testing the secondary
power supply, mainboard and controller
because it will cause of damage
semiconductor. For safety use cold ground
for secondary, mainboard and controller
board.

Same problem 2 seconds on, then turns black


The problem with the monitor is the power inverter board. I took my monitor apart and tested all the power outputs. The ones going to the main board where ok but the ones going to the backlight where different. I changed the three capacitors on the power board that where located between the two heat sinks I think it was the 1000uf and the two 470uf. They looked ok but when i tested them they where off. Next on the opposite side of the board with all the little componites there are a few dry joins that you have to resolder. If you cant find then you can just resolder the whole back board it should only take 30min. If you have no idea what i am talking about i would not sugest taking the monitor apart.

I had the same exact problem. I pulled the power supply/inverter board out and found what alot of people have seen. The T1 transformer has blown. Replacement board link here.

NEC Monitor LCD1700V


I had a similar problem with a NEC LCD1935, and I traced it to the inverter board which was a Lien Chang LI-2190 ... it seems that common problems with this type of board are bad solder joints due to the temp. cycling, or blown capacitors, but I was too lazy to resolder everything so I just disconnected the BL signal line that goes between the main board and the inverter board, and this solved the problem. In my display it was a green line, marked BL on the inverter board -- I removed it from the connector and just taped it off.  I'm guessing that this is a blanking signal that the invertor uses to signal to the main board there is an overcurrent situation and that the display should be blanked/shutdown.
I'm certain that there are still problems with the inverter and it might go again, but at least I have a working monitor for the time being.
Caveat emptor.

Dell 1800FP Dark, No Power but power supply seems fine. Help!


I just repaired 3 1800FP's - all dead, no lights.
Firstly a dead 2AS01 is 95% of the problem, because some fool designer left out the protective zener diode - cheapness.
Mouser Electronics does not have this part, but lists it at 37 cents in lots of 2500, and gettable at $2.66 somewhere else.
You must also replace the two small value electrolytics near this IC, as some had an ESR of 40 where <0.5 is where it should be.
I suppose as the electro's dry out, the spikes can zap the IC. The quacks on ebay flogging 2sa01's alone, probably hope to sell you another one down the track (at a fat markup).

There are 2 'Sam Young 2200uf' electros that really should be replaced, with ESR or 2-30 ! Ideally replace ALL electros, as the others will be off - but those 4 as a minimum and using a jewelers loupe, resolder other joints on the transformer and anything that looks more dull silverish, than the rest. A 1 inch used and worn paint scraper will get the case open easy.

DANGER, CAUTION : Finally when refitting the inverter board, ensure the steel tab is over the TOP middle of the board facing away from the power socket (SO YOU CAN SEE IT) . The board sides in flat. It is possible to scew the board down with a slight bend, with the tab pressing over the pcb tracks - very , very bad!

Now all I need is for some kind soul to improve the fix by stating what the value of the missing zener should be.

PS. Just because the caps are not bulging does not mean they should be OK. Most wrecked 10 year old power supplies have better ESR's, so the electronics must be hot under the cover.
I have seen bulging caps with a GOOD ESR, and non bulging ones with an ESR of 47.
