Sharp LC - Answered Questions & Fixed Issues

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.

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 !

Sounds like the power board is failing or there is an overheating issue. https://www.google.com/search?q=Sharp+LC+40+LE+818+Television+that+turns+On+and+Off ..

Movies and CD's that I've played before in the Sharp now read " Incorrect Disc" . Is this fixableby me or do I have to take it in for service? Thanks.

Ok I just dealt with the Sharp customer support for this problem. 1) You need to unplug the TV for 1 full minute and remove the batteries from your remote aswell (this will reset the system)
2) Hold the power button on the remote for 30 seconds with the batteries still out of the remote and the TV still unplugged
3) After the 30 seconds replace batteries then press every button on the remote beginning with the power button in order from left to right and top to bottom (same way you read)
4) Then plug your tv back in and try the remote again.... and the remote and TV should be back in sync.

... let me tell you I thought the lady was crazy when she was telling me this but it worked!

This tends to be the result of an electrolytic capacitor somewhere, either on the main board or the power supply board bursting due to overheating. In this case you can pull off the back paneling and review the boards over to make sure all the capacitors are in excellent condition. After identifying a bad capacitor you can buy one from an electronics store in the area or a reputable online source. To replace it this will require soldering. Look for a capacitor with the same uF, the voltage can be the same or higher. Make sure all the power is out of the system before servicing, also make sure to note capacitor polarity observing the negative indicator line on the side. If your not sure this can be done at home I would recommend taking it in to a servicing shop. If you do not know what a capacitor looks like do a google image seatch for both examples of a good and bad copacitor. I honestly hope it's something much simpler, I hope this helped and good luck.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty.

You cant change the aspect ratio. You can stretch and zoom programs . Some programs like movies are in letterbox and you can stretch to fill the screen, but the results are not perfect. Circles will be oval and you will cut off some of the viewable picture. This is normal

Are you really ask this? Plug it into your HDMI port, then link your Wifi to it. It will put that information on the screen when you turn it on.

Make sure your menu setup setting are correct - HDMI or other source, and make sure the signal incoming is good.

Menu on remote and make sure you have it on wide screen or 16 to 9

get the right firmware.

They are all wrong. I have this TV. What you think is an optical output actually isn't. The only audio output is coaxial and unfortunately it doesn't work with the HDMI inputs. This TV is a headache if your blue ray player only had HDMI.

Hello If your Roku 3 player is not connecting to WiFi, it is possible that the WiFi signal from the router is out of range. In order to strengthen the signal, move the router and Roku 3 so that there are fewer objects and walls between them. For any help or support just visit us: www Roku Com Link

After reading your post I can't understand what are you doing and what you expect to achieve

Try stretching the picture with the view mode button on the remote.

see the link below but first make sure here is no dvd in the drive because a bad dvd can cause this problem working on sharp lcd tv dvd combo LC 26DV20UPLEASE WAIT

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.
