Question about Dell E153FP 15" LCD Monitor

1 Answer

Having trouble Well, I work at a computer shop. But i can't seem to figure out the problem with this monitor. The power inverter was bad so I installed a new one. but now when I power this on i get a vertical white line going up the right side of the screen. I don't think its the back lights. I noticed when you just have power to it. it will show the dell test screen. but if you hook it up to a pc. it won't show anything. any help will be apreciated, kb

Re: having trouble

You have a collection of unrelated problems I am affraid.
#1 The white line is a terminal LCD panel and will need to be replaced. Repair is far more expensive then it is worth.
#2 The video card sounds like it is dead as well. Sounds strange that you can see the test signal though right? Wrong, the test signal is running through the internal section of the controller IC. As soon as you connect a video cable to the monitor it tries to swap to external mode which is damaged, hence no picture.

Check the video board for any signs of damge to the transistors at the input, time to drag out the magnifying glass.

Hope it helps, good luck =)

I have two monitors. One Samsung SyncMaster 2233 an one Samsung SyncMaster 2243. My problem is that the SyncMaster 2233 for some reason is totally black. I'm usually not terrible with these things, but my...

hello Gabriel

Could you check your SyncMaster 2233 for me and tell me your findings. If this monitor is connected from your computer and when both switch on, did the led indication lamp from your monitor lit steady green? or this lead indication lamp lit green then turns red?

1. If the led indication lamp lit steady green then there is nothing wrong with the settings, configurations, driver or hardware on your computer. The problem would be the backlight inverter lamp in your monitor is busted. Or it could be the inverter board that supplies high voltage for the backlight inverter lamp that is bad. You can replace the backlight inverter lamp located at the upper and lower part of the monitor with a replacement part you can purchase at Inverter board repair can be risky if you don't have the skill. Even opening the back cover of your monitor and replace by yourself the inverter lamp is risky too, could inflict more damage. you can bring it to a local professional service man.

2. If the led indication lamp lit green then turns red, then if not the video card the power supply section from your monitor is bad, you can replace polarized capacitor with same value. Just inspect and those with blown or leaking capacitor. You can also check the terminals and solder joints for the 15-pin vga terminal connector where vga cable is connected on your monitor. Resolder the terminals.

3. If the red indication lamp did not lit at all. Power supply section in the monitor is bad. You can check the output voltage from the power supply section. +5VDC is supplied for the main board and +24VDC is for the inverter board. Replace leaking or blown capacitor with same value.

Just remember, this should be done when computer and monitor is turn off
Post back if you have more questions. I am willing to give you assistance.

You need to check the power supply and see if the output voltage is correct, it should be written on the power supply board by the out put connector, if it is correct then it is possible that the inverter is bad.. I suspect a bad power supply.

The inverter will turn off after 2 minutes of power on.

Check to see if you do have 12v all the time, also check for bad caps in 12v supply and at the inverter section, see example of failed monitors because of bad caps:

When turned on, it immediately turns off after about 5 secs. can u help me find solution regarding this? thanks

Sounds like it could be that the lcd is going bad in your monitor. Try hooking up a known working monitor to your computer and if you get the video to stay on then you know the original monitor is bad. If you cant' get the video to stay on even with the known working monitor then you know that the video card inside of the computer is bad.

Classic sign of bad inverter. Since it is inside the LCD not something you can fix yourself unless you work with electronics. Needs to go to the repair shop.

This is a common problem across many monitors, unfortunately. The problem stems from one of two things, typically.

It is either the Power Inverter board (Inverter Mirage Electronics AD-1700 Rev:F 200-000-170DTL1 VERSION:A) or a weak or dying backlight.

If your monitor comes on for 2 seconds then you can test the backlight by using the controls to get into the backlight brightnes settings on the OSD and turning it WAY down.

If that dosen't work then it is likely bad capacitors on the Power board mentioned above. If you feel adventurous and know how to solder then you might be able to fix this yourself. You need to be careful however because you are dealing with high votage in there and capacitors CAN hold a charge long after you have unpluged the unit. You can read more about this power board as well as how to replace the bad caps HERE.

If that's not for you then I would recomend taking it to a local TV shop for them to fix. The parts shouldn't be more than $20, but labor can be expensive.
