Question about HP vs15 15"LCD Flat Panel Monitor

4 Answers

Black screen I have a HP vs 15 flat panel LCD for a little over 1 year. This morning, about 2 months after the warranty has expired the monitor couldn't wait up! I reboosted the system, turn the monitor power in, the power button stayed on for 2 seconds, then click and automatically off again. I tried to unplug the power cord and plugged in again, reboost the system and still no luck. The monitor screen stays black, no picture or sound at all. What's going on? I tried to plug it with other hard drive and same problem happened. I tried other monitor with the same harddrive,other monitor works. Does that mean this HP monitor is broken for good? Can this be fixed? Could it be a fuse?

    I have the same problem but in HP1940 monitor

    this LCD monitor uses a benq inverter board where the problem is

    HP wont give a schematis ,,dont sell spare parts

    Benq were very helpful but could not match the board

    I found a Benq schematic on the net for a Q7T4-FP71G monitor The inverter board is almost the same 90% as my HP board but the service manual only shows half the schematic The parts shown even have the small board numbers

The power supply in this monitor has probably failed, but since HP doesn't stock spare parts for their monitors you will probably need to replace the whole monitor. HP only does full unit replacements on their LCD monitor range.

HP also doesn't provide any electronic schematics so getting it repaired will be difficult.

It could be the cord between the vga card and the monitor. If it is damaged, the monitor goes to sleep immediatly because there is no signal. Check all possibilities before parting with your cash.

It's less costly to buy a new LCD monitor than having it fix.

I have a n envision 22" flat panel TV purchased


Hello,

I don't think there is still warranty for this TV. Usually, warranty last for 1 to 2 years... In summary there is not warranty for this TV, it must have expired.

To further confirm, check the receipt of purchase. The warranty duration should be stated there.

I hope you understand the above....

Good luck.

This means that you have a broken backlight. If your monitor is still under warranty you should call to have it repaired/replaced, or purchase a new monitor.
