yea that's weird, hate when stuff like that happens, double check all your connections etc. including cable. It may require calling mfr. tech support, which you will need model # name of unit etc. if a major brand, should have some tech support to go to

check the primary section of the powersupply mostly diodes and transistors inside and alo there filters.

You have a bad HOT, horizontal output transistor. It will have a number on it, and you can find it here.

Watch part replacement videos to get this working again. Also check for bad parts around this transistor if you have multimeter and component experience.

The operator's manual is available as a PDF from this URL: http://esupport.sharp.at/html/om/DataOutputDetail.php?TemplateLang=en&ID=8246 ; to download you will need to agree that you are using the file for personal use only.

Hi,
Ok I look it for you..

No, there is no fuse, it's all circuit board and fuseable links.

If you are in the US or other area that has only digital signals now, it could only be used with a converter or with some remaining cable and satellite providers. Not worth much-

Apparently it was in the satelite receiver we disconnected it and reconnected it and sound returned.

if the tv has outputs at the back for surround speakers then you can connect it to them..else pass the audio of your TV thru a home theatre surround receiver

looks like you have to replace the the tuner part (thats the slim silver box where the coax connector was ) if your handy with this solution and can repair it yourself , then you need to go to a SHARP authorized dealer to purchase the part or leave it there for repair . let me know if this helpful, thanks AJ

purchased one in March of 02 for $379.98

Try going into the setup menu and make sure the ANT input is set to cable. Then look for Auto Program or Channel Setup and let it scan and find all the channels it can receive. After it's done you should be able to go up and down through the channels.

What you see on your screen are retrace lines, it can happen for various reasons. Jut lower the screen voltage by adjusting the knob specified as "screen" on the LOT, this will disappear.

I personally would get myself a "Universal Remote". These units will operate almost ANY unit that uses Infrared... Ya Punch a "Code" in for your particular TV etc, and thats it... total conrtol...

Yeppers it certanly sounds like the tuner control curcuit or the tuner itself is bad. With the back off the set and the tV on, if you tap on the side of the tuner does the set start to work? if so the tuner has to be replaced

hi probably just a burned micro fuse on the board If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. good luck

1. Check HDMI Cable Connection: If you're using an external device like a cable box, gaming console, or streaming device connected to the TV via HDMI cable, ensure that the HDMI cable is securely plugged into both the TV and the external device. A loose connection can cause intermittent resolution adjustments.
2. Adjust Picture Settings: Navigate to the TV's menu and check the picture settings. Look for options related to display resolution, aspect ratio, or picture mode. Ensure that the settings are configured correctly for your viewing preferences. Try resetting the picture settings to default and see if the issue persists.
3. Update Firmware: Check if there are any firmware updates available for your TV. Sometimes, software updates can fix bugs or issues related to display resolution adjustments. You can usually check for updates in the TV's settings menu or visit the manufacturer's website for instructions on how to update the firmware.
4. Check Signal Source: If you're experiencing resolution adjustments while watching content from an external device, such as a cable box or streaming device, make sure the signal source is sending a consistent signal. Issues with the signal source can sometimes cause the TV to adjust its display resolution.
5. Reset TV: Try performing a factory reset on your TV to restore it to its original settings. Keep in mind that this will erase any customized settings and preferences, so you may need to set up the TV again after the reset.
6. Contact Magnavox Support: If the issue persists after trying the above steps, it's possible that there may be a hardware problem with the TV. In this case, it's recommended to contact Magnavox customer support for further assistance or to inquire about repair options.

By following these troubleshooting steps, you should be able to diagnose and resolve the issue of your Magnavox TV constantly adjusting its display resolution. Hope this helps
