Hello, you need to make sure what is broken, the remote control or the TV. To check the integrity of the remote control, you need to broadcast from the remote control while he aimed at the video camera. If you see a flicker of light through the camera it shows the integrity of the remote control. In this case the infrared receptor need to be replaced, he is placed near the stand by light.in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility that something is wrong at the microprocessor circuit. . If the remote control out of order, can be opened carefully by a thin screwdriver, usually the causes to the error are loose components or contacts that are supposed to weld back into the board.
i hope it was helpful!! Let me know if you need further guidance
Hello
Some of the secondary voltages [low voltages of 12V and 8V], either one among the said is missing inside the circuitboard of your TV. It may be due to a component [Regulator] mistake, or loose sodering joints. You just give a mild hit with your palm, on the cabin of the TV while it stops. Do not hit it with any hard material. Use your palm only for this. If Tv comes alive again; it means that there is a loose contact inside the main board of the TV. Just find the exact point, and resolder it. If this doesn't help, check for the low tension voltages. As the red light flashes, means 5V power supply inside your TV is ok. Check the other two and the main supply rail, normally 125VDC, and related componets fitted with it. There may have a small value resistor in series with this power supply rail to LOT [usually less than 2 Ohms or so]. It will generate a small amount of heat while working. Check its sldering contact also for loose contact.
yes if the computer has the proper outputs. you need either composite. those are the yellow, red, and white. componet those are red, green, blue. video, and red and white audio. s-video. most of the tvs. with the exception of lcd and plasmas wont sync to the standard vga input on the tv.
im sorry my friend I do not understand what a funny marrior is? LOL If your complaining about white lines at only the top of the picture, then I would say that your problem is with the vertical sweep circuit. Most likly a capacitor in the vertical preamp really small ones next to the jungle IC or the capacitors that are used as waveshapers in the vertical drive and output. If the entire screen is white lines then the screen drive is too high so back it down till the lines just disapear. if that wont turn down, theres a filter cap on the sweeop supply or the CRT socket board is bad. Good Luck
Since the problem is common on two remotes, the source of your misery has to be inside your set, not with the remote.
The receiver in the set may not be positioned as it should be since it is rare to have either end go 'a little bad.' They generally will fail totally instead.
Any shop that services TVs will have a simple pen-like detector that will tell you if the remote is putting out enough signal to work as it should.
If your set has ever been repaired, the main board may not be sitting in the slots that act as supports.
You might try to hold the remote in several different positions; holding it below the IR window and pointing it upward, the same for each side and then above the window.
If it seems to respond better from one or the other angle, then the receiver is not sitting square behind the window.
The green gun in your picture tube is set a little too high.
If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT.
BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS
I hope this may help you.AGAIN BE CAREFUL!!

this is a signal fault.
it might be due to
1 you are getting weak signal
2 cable wire quality is poor
3 tuner portion of your tv might be a problem that is loose contact or tuner it self defective.
4 also there might be a problem in aft section in your tv(if all are normal)
Not likely convergence because it's simply a direct view TV. Could be vertical, a common problem with that unit is the vertical output IC Q301 and poor solder connections of the link off R305. This could be enough to put the unit in shutdown. And it could also be SMPS, possibly regulator or horizontal output transistor - you would need to test these to be sure. The HOT, if shorted, will have continuity E to B or E to C..
If you're not sure you're up to this take it to a reputable shop. What I've described above isn't too serious and a good shop can having back to running good as new in a couple of hours.
One tip I might add, take to the shop yourself it will save a few bucks.
Good Luck

This is a known issue with this TV. The following might resolve it:
Check Mute and Volume:
Ensure that the TV is not muted and that the volume is set appropriately. Sometimes accidental button presses can lead to muted sound or low volume.
Inspect External Speakers:
If you're using external speakers, verify their connections. Loose cables or faulty speakers can cause sound issues.
Test Different Inputs:
Connect a non-HDMI device (such as a DVD player) to the TV. Observe if the sound distortion occurs. If it doesn't, the problem might be related to the HDMI signal from your Virgin box.
HDMI Troubleshooting:
If the issue persists with the DVD player over HDMI, consider the following:
HDMI Cable: Check the HDMI cable for damage or loose connections.
Virgin Signal: Contact Virgin to inspect the signal/lines and replace the box if necessary.
Mainboard Replacement (if needed):
If the sound distortion persists, it could be due to a faulty sound processor chip on the TV's mainboard. In this case, consider replacing the mainboard.

There may be loose contact or track open in main board.So try to check the main board thoroughly where you may find the loose of connection or track open.
Locate the Battery Cover: Look for the battery cover on the back of the remote control. It is usually a small compartment that can be easily opened.
Remove the Battery Cover: Depending on the design, there may be a latch, screw, or sliding mechanism to secure the battery cover. Use your fingers or a small screwdriver to open the compartment.
Remove Old Batteries: Take out the old batteries from the battery compartment. Pay attention to the orientation of the batteries, so you know how to insert the new ones correctly.
Check Battery Polarity: Take note of the positive (+) and negative (-) signs inside the battery compartment. Make sure to insert the new batteries with the correct polarity to match these markings.
Insert New Batteries: Place the new batteries into the battery compartment, ensuring they are properly aligned with the correct polarity. Press them down gently to make sure they are secure.
Replace Battery Cover: After inserting the new batteries, close the battery compartment cover securely. If it has a latch or screw, make sure it is fastened properly.
Test the Remote: Point the remote at the device it controls (such as a Toshiba TV) and test whether it responds to your commands. If the remote is working correctly, you have successfully replaced the batteries.
Dispose of Old Batteries: If the old batteries are no longer usable, make sure to dispose of them properly. Many communities have designated recycling locations for batteries.

They are purely a numerical identifier of when it was made, year, day, number on the shift, whether it Joe or Billy who did final inspection.
With a MODEL number I can find them easily with just 'make model manual'.

No you can't the Insignia remote is for that model television only. Companies don't make their remotes so they operate other makes of televisions. Buy a Copy Remote for the Toshiba
