Question about Sharp Aquos LC-37HV4U 37 in. LCD HDTV
Unit is five years old and until now no problems. Following suggested power up process (1) dispplay Main Power on yields red to blinking red expected. (2) AVC Main Power on and Display red goes off. Attempts to immediately repeat sequence yields no red light on Display when pressing Main Power button. Can only repeat process after diconnecting power cord for Display and AVC unit for an hour or more. Was able to gain normal expected Display functionality once, over two day period in the course of following these steps, maintained normal TV operation. Following normal shut off, back with same problem.
This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.

Sharp aquos 32 I got same issue with the flashing red light, however when i remove the dvi-d connection cable from the avc system and connect it to my computer it works without any problems. I'm going to try a converter ive got which i use to connect my old crt tv with my computer ill need some cables to do that and then connect it to my freeview box and see if that works. If it doesn't the only solution i see is to throw away the avc system and use tv as a monitoras a computer monitor.I'll let you know if it worked in few days.

Same problem here 2003 LC-37HV4U, AVC unit just stopped working. Sharp wants nothing to do with it and won't help in anyway. You can buy a reman avc for $800.00. Best bet is to throw it out and buy a Sony.

OK. Here seems to be a solution that is working now. Unplug both the
AVC and the panel (I used a power strip to make this easier by just
turning off the strip and back on again). With the AC removed, press
the "MAIN POWER" on. Next, press and hold the "VOL (--)" and "INPUT" at
the same time. Finally, plug the AC power back in and the set should come on.
After it came on, mine was in a factory test mode. I had to enable the write mode (I think it writes to the PROM) and then selected the second line down on the first menu (1 of 15 ) to have it do the restore or something.
Finally, my set came up with OPC enabled to auto and it seems to have a sensor issue. At night, the monitor is unwatchable with such low light. So, I turned on a bright light near the monitor and set that to "Manual". so far, for two days and nights now it has been working again. I hope this helps. Good luck! -Brad

how many blinks does the red light give in a row? This would be an error code?
The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. You can replace the board with a new one and update the software on the new interface board.
If is isn't 7, let me know and I will help you out with this
