Question about Hannstar I-Inc TW-191D Monitor

1 Answer

My TW191D Monitor will not power on. It was sudden and there was no indication that there was a problem developing. It happened after a power outage, but not directly after it. Can anyone tell me what they think is wrong with my monitor and maybe what I can do to fix it. The manufacturer was not helpful at all. Thanks

    Situation is that monitor DOES have power going to it, the green light is on, indicating that the monitor is powered. However, I have a black screen, but if I turn the monitor off, and then repower it, the screen comes "on" for about 5 seconds, then goes off again. There is a very slight "hum" when the screen is actually displayed, no hum when there is no display.

    Theelectr887, I can only guess that your monitor's power supply has stopped functioning. What kind of power supply do you have? internal? or small inline sitting on floor black box?? What happens to the led/on/off power button?? any light? How old is it? If you are not familiar with what are known as line operated "switch-mode" power supplys and know how to use a digital voltmeter(DMM) and possibly a 30mhz oscilloscope with isolation transformer, then you have very few options to deal with. Option A: Find out if manufacturer has swapout program. you send dead monitor and some cash. They send you a REFURBISHED same model in return. cost $ 40 to $ 90.

    Option B: Locate local TV/Audio/Video/Monitor Repair shop that knows all about CCF tubes, power supplys (both Switch-mode and INVERTER types) and knows enough stuff not to destroy his/her $1200. oscilloscope while troubl shooting your $160. monitor. cost min $25.

    Hope this helps you. You have joined the ranks of thousands of others that have LCD monitor problems. Best of luck to you. I'm louie12fix on fixya. or lmistyrel @aol. com

Maybe bad caps (capacitors) you need to be familiar with high voltage(200VDC iguess, here it is 400VDC) to do anything of your own.

It would be nice if all badcaps are bulged/leaking. Changing the lamps is a pain in the ass, i will try it myself with an 191d. But i have tried first the power supply with multimeter capable of 100kHz AC 200mV range. Better if you borrow an ESR meter capable of in circuit measurement and test all condensators.

Allways discharge, disconnect from pc, switch iMonitor on and pull wall plug, push ON button for safety. My 400V capacitor is then down to 7VDC (germany 230VAC mains). Or wait for 30 min, (i am not patient enough for that).

My TW191D monitor went blank with a flashing green light. I changed the cable nothing. I tried the monitor on 2 other computers and it work fine. It still will not work my computer.

Since it works with other PC then the problem is in your PC, it can be video card, RAMs. Try reseating the RAM and teh video card. iT can be *********** board also. Need more troubleshooting in your PC.

No pic on monitor


Check all the connections to the monitor, ensure they are all intact, replace any cable suspected to be damage and see if there is difference, if no difference, this indicate that the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

No power but ON button flashing

Quickest fix for this is probably to temporarily unplug the monitor power cord.

For your other outages, I assume the monitor is connected to a computer, make sure the operating system power-save features have not disabled the video output signal from the computer ... if so, monitor should re-activate when you use the mouse or hit a key on the keyboard.

If your computer has two video outputs, make sure the primary display hasn't been shifted to the other one ... try it by moving the LCD data cable to the other video connector on the computer.

I had a similar problem with a Dell monitor after a power outage. I pulled the monitor apart and found a connector not completely seated. I think that something internal has happened to your monitor. It could be an internal fuse or something. If you don'r feel comfortable taking it apart, find a reputable service center.

Problems After Power Outage

Sounds like the power outage damaged the video interface could be damaged. You might have had a spike that effected the red input of the monitor. You can try to order a video interface, or like I suggest to others, look for the same monitor but broken on ebay and swap out the interface board. Chances are this will fix your problem. Good luck
