Hi my name is Eric,

I hope I can help you with your issue,

You say the red power light is on?

Do you hear a click when the TV is first plugged in?

Are you wanting to get an idea what a repairman will charge or did you want to open the TV yourself and attempt to fix it?



If you need more assistance,please tell me your technical ability,

1 I can solder and check voltages and want to know what board/part is bad so I can fix it myself

2 I am pretty good at figuring things out, but do not want to open the Tv up

3 I just know how to turn on my TV

This way, I can help you without getting to technical unless needed.

If I have helped you with your issue please click accept.

If you have more questions you can still respond until this post expires,

I will reply asap

I will be retiring to sleep now but will check your answers in the morning. Suzanne

Expert:  Eric replied 7 years ago.


sorry about the delay

please confirm that 30HV4U is the exact and only model number?

Is this a USA or non USA model?


I wanted to download the service manual to verify if there is a main fuse and switch,

some of these have a power switch near where the AC cord goes into the TV.

Please verify that the cord is plugged into a non switched outlet and that the TV is secure, look for a switch near the bottom .

I am looking for the manual.

Good morning Eric,


I am located in Montreal, Quebec, Canada and that is where I bought the Sharp Aquos LC-30HV4U.


I have the manual here and I have tried what they suggest in the trouble shooting section to no avail.


Here is what I did this morning .


I changed the power bar, re-connected the AC cords ( to the system and the TV) .


There are no switches near these connections.


The only light that comes on is on the system and it stays red - but no lights or click happen on the TV.


I do have a dvd connected to it. Should I try to remove that?


Thank you very much for your assistance . Any suggestion is welcome. Suzanne




Expert:  Eric replied 7 years ago.


The avc system is cabled to the TV right, did you disconnect the AC from the system too

That would reboot it.

Otherwise you need a service tech

It could be just a fuse, but unless you want to open it up and start taking things apart we won't go there. I have replaced fuses in a few sharp LCDs , 8amp 250volts.

If you call a repairman you are most likely going to spend $250 for just a fuse

$500-$600 for a power supply

Let me know if there is anything else I can help you with

Hi Eric,


I guess that is what I did not want to hear !!!!


I will try to find a Sharp technician here in Canada and bring the TV in for an assessment.


Thank you anyways. Suzanne

Sorry to be the bearer of bad news

Best of luck with it



Customer: replied 7 years ago.



This is the first time I use this service . I am suppose to ACCEPT this deduction?



Expert:  Eric replied 7 years ago.


Yes it would be nice of you to click accept.

Remember on your TV if yours comes with the AV control box, the repairman will probably require you to bring (if you are bringing it to them), the TV connecting cable and AV box. I had mentioned rebooting not just the TV, but the box also (hope you tried that)

Best of luck
