Question about 3G Technology GM-190B (Black) 19 in. Flat Panel LCD Monitor

Where to buy inverter card

Inverter card appears to be a Winmate QF132v1.1x or possibly model QF132v1(a). I can only find Taiwan wholesale companies, not anybody who will sell me one board. I live in the USA so hopefully there is a distributor in the USA. Is any other brand/model compatible ?

We are in need of the same board. It's used in a MASS C-19 monitor.

Upon power-up, the display comes up briefly, a "pop" is heard, and the display goes dark. Powering up with the screen opened up reveals a slight hiss from this board during the troublesome power-up phase.

My 19" Gem monitor came up w/ the same problem after about 3 years of service. The inverter board has 2 black square components (1.5 cm x1.5 cm or so, .8 Cm high). The brief "hiss" on powerup is coming from the right one. I had to hold a peice of paper over one at a time to hear which one it was coming from. I un-soldered it from the PCB (9 solder joints, surface mount), and was then able to see 4 copper coils. One coil has a heavier gauge (and fewer windings) than the other 3 windings. No visible signs of stress, no burnt smell. PCB has P/N QF132V1(A), Patent NO:171823. other numbers on PBB: 94V0(a triangle)E171781(S)

The black square thing with the coils inside has a sticker: QF132V1.16, and under that AZL 0451. This number seems to be the inverter board part number, not the component part number.

Because the black square thing is where the noise is coming from, I would love to find another and replace it. I may swap the two (black square things) on the PCB & see if the noise moves

If anyone knows where to get the same inverter board or the suspect component, I would love to find out. Mostly I would just like to tinker with it to see if I can fix it. It may not be cost/time effective, because i can pickup a new 19" monitor for not much more than $120.00 (US)

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.

I buy a new power inverter ERP 2300 12v/220Volts

What does the inverter over 600 Watt.
By what type of battery is the inverter supplied? How many Ah? What is its state?

In order to achieve 1000 Watt for 1 hour you need a fully charged 12 V / 100 Ah lead-acid battery.
If your battery is less then 100 Ah and is not very well charged or old (bad) you may not have over 600 W, but not bacause of the inverter, but the battery.

If your inverter stops due to low input voltage (you can see it in the digital display during operation).

If you want to check the real output power of the inverter you should connect it to a big (more than 200 Ah) well charged battery.
