I have a 55 inch JVC tv,today the screen went black but still have sound, also the buttons on the back wont work, but the channel down button turns it on and off? What is wrong with it?


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..

I cannot get the tv to go to channel 3


i'm assuming that it works fine for other channels...most TV's have a "program" feature. This will search through your channels and see which ones are actually broadcasting so that when you flip through the channels you only get ones that actually have something on it. I would try to re-program your TV...

sometimes there's a program button on the remote. sometimes you can find the option in the menu screen.

Hope this helps,
Thomas

No sound on my tv


Hi, I think there is some problem with your TV Speakers.  And regarding your TV remote, it may also be damaged.Either you buy the new remote or give it for repairing Please call a TV mechanic. He will repair both speakers as well as remote.
But it will be better if you buy a new remote.
Thanks!

Recorded programs in english come out in Spanish


Make sure your TV hasn't been set for SAP (you'll find it in the audio settings menu). Second audio programming is often used to carry alternate languages, and if it's turned on you won't know it until you watch a program where it's being used. There may be a single button labeled SAP on the remote. If so, it's easy to change the TV setting without realizing it.

VCR/Cable TV Connection


I guess you are using the cable TV feed looped through the VCR to the TV set.

Make sure you did not confuse the in and out loop of the VCR.

In the VCR menu, or on the remote there is usually a button called TV/VCR (Video). Make sure it is in the TV mode to watch the cable. In the VCR (Video) mode, the TV must be on the VCR's designated channel to watch the VCR, and the VCR tuner is used to watch the cable channels.

TV JVC av27020


Does the screen go black with the volume still working ? If so check to make sure your closed caption is turned off . If the sound turns off as well like the tv is turning off , then it might be going into shutdown. Some of these sets have had bad caps in the startup circuit . Let me know , Good luck

Sony bravia intermittent sound


Yep, same problem with mine. After many trial fixes, I discovered that it's the HDMI connection. I tried two different new HDMI cables in two of HDMI ports on the TV, but still got intermittent sound. The only way I solved it was going to component cables (RGB) with a separate audio cable. Works great now. Other Web sites say that HDMI connections do not always electronically "handshake" well between devices. Not sure how this HDMI problem can be permanently fixed, but using the component connection works fine.
