You did try the CLEAR button on front of the box?
One possible idea is the cables going the box to the TV. ( might be bad )

If your sure about the problem, you can get your Service Manual here:

This with have all the schematic, diagrams, part number, and test points you need.

My sharp aquos 30 inch tv will not come on. what could be the problem


Hello; I have an similar LC30HV2U for sale in my TV repair shop for $350. This is a 2 piece unit. The AV box and the monitor. I am also a Sharp authorized servicer. In the monitor there are 2 inverter boards on the right side that have an 80 % chance of causing this problem. This set counts "lamp errors" due to one or more inverters not working on startup. Once the set accumulates 5 lamp errors, It will not allow the set to come on. The first thing Sharp tells us is to replace both inverter boards. About $90 each. If those don't fix it the cost will go much higher due to a bad power supply board or bad LCD Panel. Hope this helps, John

Sharp lc-22sv6u won,t power on. no green light.


Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs


I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.

Power supply bad on Sharp Aquos LC - bad board - schematic to ID?


Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.

Let me know how you do Kathy ?

Sharp aquos has green and white vertical lines


You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.
