20 Most Recent JVC AV-27S33 27" TV Questions & Answers

I would guess you are using an antenna or a cable service without a set-top box. When the TV is using HDMI or component video it does not employ the decoding for the color as like when using an RF feed. Most people of today do not use RF directly in to their TV set using the built in tuner. They feed a desk-top box that feeds a decoded picture in to the set via the component RGB connectors, or they are using HDMI. When viewing an RF signal from the antenna or cable using the TV's internal tuner, check the video settings. make sure the setting for Color is turned up to 50% of its range to start with. If there is no color, check to make sure the Settings are correct. Check to see if the TV has a black and white mode, and this mode is turned on. Check to see if the TV receiver section is for your location type. If you have a set from another country that uses another broadcast system for color this can be an issue. It is also possible the TV set's color decoder for RF reception is defective. This would require proper service. You would not be able to service this yourself. Based on the info you supplied these are the best suggestions I can think of...

Displaying greens screen is a bad symptom indeed. You should suspect its display paneel. Contact any service technician, and make it sure.

Check its color system adjustments. It will be best to make a factory reset to this set. Just unplug the TV from AC mains wall socket, and re-plug it after 10 minutes of so. This must make your TV a hard reset. If this do not help you, the chroma section circuits of your TV need to be checked for fault/s. This is a skilled work, and it will be best to contact any experienced service technician.

Turn the tv on now see if the tv colors changes to a different colors,not make fist with one of ur hand bang the tv bazel of the tv frame.If the tv colors changes and flashes.Than the tv video board that the board connected to CRT(-tv tube) for tv video picture the video board have to be check out for lose and cold soldering pins holes joint on the video board connections between the video board and the CRT-(tv tube) together.Must be resoldering for a tight and good connections between them to solved this problems.Take the tv aparts.U have a soldering iron and a roll of solder.A resoldering job will fixed this problems if bang on tv bazel frame changes colors.

This could be several things. At its best you have an open resistor near the flyback. You may have a bad ground on a color output transistor, or a bad ground on a color output resistor. These are located on the small board connected to the CRT. In really bad cases you may have replace the transistors, or resistors. But in worst cases, and I do believe its true, you have a bad picture tube. I would not recommend a repair. I have seen this problem with many, many TVs of any brand. You are smarter to purchase a new TV. Thanks for asking and show all hands of support!

Hello,
I just wanted to suggest some things for you to try, if you have not done them already. Try hooking up a known good signal, such as the main input cable from your cable or dish, hook it straight to your tv, and see if you can change channels, and get a picture on low band...2 thru 6, and then if not, how about any picture above channel 6, if you get picture on 2 thru 13 now, it could be whatever you have hooked in between the input cable and the tv...be sure you have the tv on the right channel for your receiver, usually 3 or 4, or if you are using another type of video input cable, make sure you have tv on the right input for that cable and that cable is good...check the in and out of your component unit, for correct cable hookup as well as your cables, in reference to using RCA video and audio left and right in and out...a lot of sets and vcr's will go to a blue screen if they lose signal to them....I hope this helps you out some.If you cannot get a picture from hooking your signal straight to your tv, it could be the tuner got a spike from a thunderstorm, or has lost the B Plus source for the tuner circuit. Be sure that it is not selected for an input signal,other than the cable or antenna mode, the onscreen text should verify this, if you can change channels with or without getting video...a picture....Good luck with it. T.

It sounds like thats the maximum number of channels it can tune or you are probably scanning either analog/digital channels only. Is the model number that you have listed correct?

Sorry to tell you this, but that's one symptom of a bad picture tube. After it's warmed up a little, one of the elements in the neck touches something it shouldn't and you see the result. There's no repair except a new tube, and that's completely uneconomical. It would be less expensive to replace the set.

please turn off the sap mode thats the second audio play mode in this case for spanish

I've found several bad solder joints on the neck board of my JVC 32' leading to the exact same issues as yours. Inspect the Driver resistor solder on the neck board.

set is in the text mode.

**WORKS**

In my case, the adjustment was available from outside the TV. Sortof. On the rear of the TVabout 2 inches to the right of the coax in, there are two vertical slits on a little protrusion. Inside the slits are the two adjustment screws. The lower screw adjusts brightness, the upper screw adjusts focus.

Have you move the tv or is there a speaker that you might have move close by the tv?

turn the tv off for an hour and turn it back on see if the degaussing can correct ir other wise it may have a bad connect on the degaussing or you have some kind of magnetic device close by.,

Does it have a video input? Does it have color when playing a vhs tape or dvd into the video input?

Does the set show the raster lines? Is there any snow showing on the raster?

If the set does not show color with an a/v input either then it is likely the main power supply section feeding the deflection system or the video processing is bad.

RCA sets more than a few years old are not good investments for repairs, unfortunately.

Let me know the answers to the questions above and I can give you a more precise suggestion.
 
 Good Luck

Hello! If your JVC TV is displaying an onscreen remote and you're unable to use the actual remote, you can try the following steps to resolve the issue:

1. Power cycle the TV: Turn off the TV and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can often reset any temporary issues and restore the functionality of the actual remote.
2. Replace the remote batteries: Check the batteries in your remote control and make sure they have enough power. If the batteries are low, replace them with fresh ones and try using the remote again.
3. Check the remote control sensor: Ensure that there are no obstructions between the remote control and the TV's remote control sensor. Clean the remote control sensor on the TV with a soft, lint-free cloth to remove any dust or debris that may be interfering with the signal reception.
4. Reset the TV to factory settings: If the issue persists, you can try resetting the TV to its factory settings. Keep in mind that this will erase any personalized settings and restore the TV to its original configuration. Refer to the user manual or the manufacturer's website for instructions on how to perform a factory reset on your specific JVC TV model.
5. Contact JVC customer support: If none of the above steps resolve the issue, it's recommended to reach out to JVC customer support for further assistance. They will have access to more specific troubleshooting steps and can guide you through the process of resolving the issue with the onscreen remote.

Keep in mind that the exact steps and options may vary depending on your specific JVC TV model. Refer to the user manual or contact JVC customer support for model-specific guidance.
