IT might be blown capcitor

If a capacitor blows out, then it is probably having a higher voltage
on it than it is rated for. You don't say what the voltage rating was
for the original capacitor or what the voltage rating was for the
replacement. Did you try to measure the voltage in the 10 seconds
before the replacement blew??

This is a power source problem and it will need to be fixed by a pro! This is a very common problem with the Sylvania sets! (cost to fix 250.00-350.00)

This is an EDTV capable of 1080i over component cables. It will also display 480p & 720p. Most likely its the video source determing the resolution you are seeing.

No. They are entirely different. Panasonic was the supplier of the 6842PE and Funai was the supplier of the 6842PEM.

That board has the Sylvania part number 1EDM10583 and the price is about right. It might also need some adjustments after installation. Sylvania has no circuit diagram for that board. The TV was assembled by Panasonic and also was used in a Magnavox model. Panasonic may have had the power board designed and made for them by someone else. A technician would have to have some very good luck to repair a board like that without a schematic. Sometimes board rebuilders like PTS have the capability of repairing a board like that. You just have to ask them.

The service manual troubleshooting procedure says to replace the control circuit board and if that doesnt fix it to replace the display panel.

You need an HDMI cable that runs from the cable box to your tv.

There should be a circuit designation for this part marked on the PC board, for example C631. Start by posting that designation. Having that will allow anyone with access to the service information to post the value of the part.

What is the make and model for your unit? Which state are you located in?

There is a button labeled "ZOOM" on your remote control, press it to cycle the ZOOM settings.

It happened to me.. a FAx to Enrique. in California.

Try the code 052.

You have a power supply problem ,most likly the main board will have to be replaced, My best advice is to call out an authorized Sylvania dealer because if you make a mistake on what board is bad, they will not take it back. Play it safe. Good Luck

If you have it hooked up to a cable box, then you should be abl to change the resolution setting through the cable box remote control, if not call your cable provider to access the menu that does the resolution settings

this may be filure of your tv's vertical section of the circuit.

No, because screen casting wasn't invented and it isn't a Smart television. Time for a new one.

Here are some troubleshooting tips to try. However, as it is an older set, if these tips fail, the cost of a repair at a shop might exceed the value of the TV. In short, a new TV may be in the works. Cross your fingers. One of these tips may work. Let's troubleshoot the issue and try to get it working: If you are using a remote, check the batteries in it. If you are using several remotes with it, try the alternative remote. Sometimes there is a glitch affecting the remote for a Roku where it won't turn on the TV other than a powered black screen and you have to use the other remote to turn it off and back on and then the Roku screen pops up. I have not sorted out why. Check Power Cord and Connections: First, ensure that the power cord is securely plugged into both the TV and the electrical outlet. If you suspect a faulty power cord, consider trying a different one. Reset the TV: While most Sylvania TVs don't have a dedicated reset button, you can perform a manual reset: Unplug the TV's AC adapter from the electrical socket. Press and hold the Power button on the TV for 20 seconds. Plug the AC adapter back in and turn on the TV. Check Audio/Video Cables: Inspect the audio/video cables connecting your TV to the satellite or cable receiver. Ensure that the color-coded prongs match their respective connecting points. Correct any mismatches (e.g., white cable into a red port) by reorganizing the prongs. Inspect Coaxial Cable: Look for the coaxial cable on the rear side of the receiver, attached to the port labeled as ANT IN. Confirm that the connection is firm; a loose coaxial connection can cause display issues. Tighten the cable by pinching the silver band on the end and rotating it clockwise until secure. Check for Interference: If distortion continues on the TV screen, consider nearby interference. Power-hungry appliances can cause electronic interference, affecting display quality. Visit a Repair Shop: If the above steps don't resolve the issue, you may need professional help. Some technical faults, such as a blown fuse or faulty capacitor, require expertise in dismantling and soldering. If uncomfortable with such tasks, consider visiting a repair shop
