Question about Hanns.G Corporation JW-199DPB 19" LCD Monitor
I have 2 CY199D monitors. About a month ago unit 1 would not come on and the blue power lamp flashed from off then amber then blue in some sequence. Pressing the power button has not effect, won't go on or off. The screen is completely dark with no sign of life. I called for support but I-Inc , now called Hanspree (or something like that) said they though the board was probably defective and the part is 1/3 of the unit cost. It was 1 month out of guarantee. They said that there is nothing that can be done to reset the unit without the display up.
OK a bad unit. Today unit 2, which is less than 2 years old and also out of guarantee, did the same thing. I turned the monitor off because I have been away and when I turned the system on I forgot to turn on the monitor. The computer was up when I turned on the monitor but the display did not light up and now the power button no longer functions and the lamp does the same thing. I tried disconnecting the power for a while but to no avail.
I was not present when the first monitor quit but I suspect that the sequence was the same.
Anyone have any suggestions besides throwing the monitors away and staying away fron I-Inc?
The problem is the program for the graphics card is stored on a 16K serial eeprom which is used as a rom this can get corrupted which causes the problems you are experiancing.
I have repaired three of these monitors by re-flashing the eeprom with a program cloned from a working monitor all worked fine after refashing.
Now the bad news as the eeprom is used as a rom it is write protected on the board so the only way to program it is to remove it flash it with a valid program and then replace it easy if you are a surface mount expert.and have a serial eeprom programmer.

I just confirmed on my monitor.. same symptom.. it was the 8 pin serial rom on the cpu card of the monitor (with the video jacks). 24lc16b IC replaced and i have a working monitor. $.28 part and $6 shipping.

I also have a CY199D which has the flashing blue light of death! Clearly this is not an isolated problem but an ethical problem. With this many defective units floating around, Tiger Direct knew you would eventually have problems with this unit and chose to take your money anyway! These units seem to be built as disposable units which I find environmentally disgusting! I suggest you share this experience with as many people as possible and let them know exactly what kind of retailer TD is.
Ps. this is actually my second unit...my first unit had all kinds of burned out pixels on the screen and TD didn't want to exchange it...the unit was about 6 hours old at the time I brought it back to the store! Can you spell CROOKS?

Is it possible to perform the firmware update on this monitor as I have the same problem and will not pay the money for the company to solve what is clearly their own quality problem. Appreciate the assist from anyone that knows.

Here is what I did...I have no technical experience but I bought a similar model unit with a cracked LCD screen on ebay (Hanns-G HX191) and then swithced the screens. I took the cracked one out of the HX191 and replaced it with the same size screen from my CY199....perfect working monitor! Just threw tho old one out! Total cost: $28.

To jeb3: The part in your picture is not the transistor. The switch transistor is the one mounted on the aluminum heat sink. If your monitor has the flashing LED problem, it's not the power board, it's the other board. Many have said the problem is the firmware. My monitor had the same problem and I have no idea how to fix it.

Adriananders, can you upload the firmware somewhere? i don't have a working unit to read from, but i am entitled to a copy for the non-working unit i do have.

There are two of those screens here at the lab I work at; one is good and the other does what has been described (blue-amber-repeat). By part swaping, I found that it is not the power supply, but the video processor board that has the DVI and VGA connectors on it. That means that it is not the switching transistor. Normally this type of problem is caused by the power supply board but in this instance, the power supply is not to blame.
