Flatron l17175 has it internal wireles receiver

I think you need TV tech to check for some busted parts, its internal problems .

lcd lg flatron w1742st no pawer

Those screens are so inexpensive, it really isn't worth your time to try to repair them...Spend a buck and use your time for more important things!

Try any other receiver that uses HDMI connect it to you LCD Monitor then that will tell you whats faulty.

this sounds like the internal power board or video board has gone bad, the capacitors have probably gotten too hot and started to leak, like an old battery (they contain similar substances), when cheap capacitors are used this happens sooner rather than later, just like when you use cheap batteries. this could be fixed easily if you are good at soldering, otherwise you should send it to be repaired professionally.

This is a common issue, the power supplies in LCD monitors fail prematurely. (if your monitor has an internal power supply) , Double check all your power connections, but it sounds like the internal supply is toast, (its a simple capacitor replacement to fix, but cost to do this job seems to always outweigh a new monitor purchase) sorry to be the bearer of bad news.If you find my answer helpful albeit poor news, please use the thumbs up feedback.

Wireless device won't work for bluetooth.
You need Bluetooth Transmitter and Receiver.

HI,
your monitor is not working properly, bcoz monitor data cable no connected properly into the System or any internal problem in your monitor.

Thanks

have u checked the internal fuse take the back off and look for a glass fuse

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!
