Problem, unable to access any digital channels. TV
If the database is empty you need to re load the system.
With your remote controller, go to menu and from that you need to select install or setup.
This will scan for all available channels and store them for use.
Hope that helps.
Changing analog to digital on Sharp TV
Unfortunately, you cannot convert an analog TV to digital simply by changing settings. The transition from analog to digital involves hardware changes. If you have an older Sharp TV without a built-in digital tuner, you may need an external digital converter box or consider upgrading to a newer TV with a built-in digital tuner to receive digital broadcasts.
What is opc that pops up about every 10
OPC is optical picture control. The television is adjusting itself to the lighting in the room. Even if someone walks in front of the television's sensor it will start to adjust and you will see opc on the screen and green leaves.
You can leave the feature on without the opc and green leaves appearing on the screen. Press the menu button. Scroll down to OPC. Press enter. Scroll to on. Press enter. Press menu to exit.
Is it normal for opc
You can turn this feature of in you menu. It is adjusting to change in roomlighting when you see this come on. Look in your menu for OPC on off setting under features menu.
Sharp TV Audio Problem
Almost all intermittent audio or audio failure problems with Sharp Aquos LC**D4U, LC**D5U, LC**D6U, and LC**D7U televisions are the result of a relatively simple design flaw involving the heatsink pad compound used on the Tripath TA-2024 amplifier chip (IC2502) found on the A/V board. This compound has a fairly low melting point and, over time, tends to seep out from between both top and bottom heatsinks onto the legs of this chip as well as onto circuitry immediately surrounding it. Further, over time the seeping compound also becomes somewhat conductive creating bridges which short the audio amplifier circuit causing everything from intermittent audio to complete audio failure.
Fortunately, in almost every case audio can be completely restored by cleaning the old compound from both top/bottom heatsinks and from both sides of the PC board in the area immediately surrounding the chip (I used rubbing alcohol which worked quite well). Sharp has issued a service bulletin addressing this issue (LCDTV-194) wherein a ‘2502 Heat Kit’ is specified. This kit is Sharp Part Number: PSPKIT663WJZZ and is available from circuitcity.partsearch.com for $19.95. However, it’s entirely possible to get by with the heat pad only, Sharp Part Number: PSPAZA663WJKZ for only $9.95. Please note that board replacement for this problem is almost never necessary, so if you’re working with a repair technician be sure and insist that he/she be certain to try cleaning the old board and replacing the aforementioned heatsink pads before charging you for a new board.
If one is reasonably familiar with electronics disassembly/reassembly and is willing to take their time, this can even be a DIY project. It is possible to find ‘important service references’ by simply entering LC26D4U (the 5, 6, and 7 series are very similar, and this information covers all screen sizes) into the search field at eserviceinfo.com. This will greatly aid in disassembly/reassembly of the TV, as the A/V board is somewhat ‘buried’ under other boards. Please refer to post # 373 at avsforum.com/avs-vb/showthread.php?t=647174&page=13 for pics of the information detailed here.
Particular thanks are owed ‘Aureius’ of the AVS forums for his research efforts concerning this issue !

Sharp 60LE600U stand by light is on, backlights come on and go right back out along with the standby light?
From the past history of Hisense brands of TV's the power board very seldom gives issues, they build them quite well, the only way to troubleshoot this issue is with a multimeter, look for the power on pin on the power supply connector going to the main board, you need to see about 3.5 vdc there when you turn the set on, I think you will see the voltage there for a few seconds then drop to almost 0, if you find this it's the eeprom that's lost it's data, this IC is located on the main board, there are 2 fixes, one is to replace the IC the other is replace the board. The chip costs under $20 but it's somewhat difficult to replace. Here is the listing for the IC https://www.shopjimmy.com/sharp-dkeymf905fm04-kf905-qpwbxf905wjzz-main-board-loc-ic8401-eeprom-only/
