JVC model HD-52G456 55inch TV shuts off after about an hour.

Is it the bulb or is it due to my TV being plugged in to the DVR and not the wall socket?

It may be that you have your tv plugged into the dvr. You would need to have your televison plugged into a reliable surge protector to protect it from surges. Your rear projection can be the most sensetive home theater component that you may have. Be careful of pulling the power from the television,, this can shortnen you bulb life. Allow the television to shut down until you hear the fan turn off. After doing this go into the menu and make sure you dont have the sleep timer set on your tv, if it is just put it back to zero.

Hope that helped....

It could be dust and or lint in the tv. The bulb has a fan to cool it and if it is plugged with lint can cause the bulb to overheat and fail. Lint or dust that gets on the bulb can also cause premature failure. Remove bulb and lean fan and intake screen thoroughly and check to make sure fan is operating. Then install new bulb. Hope this helps.

Reboots then shuts down again


To unlock the Channel Master CM7000PAL DVR:

1. Unplug the recorder from the wall outlet and DISCONNECT THE ANTENNA. Now plug it back into the wall power outlet.(This will keep the recorder from freezing and rebooting)

2. let it go thru it's normal bootup, tv guide search, etc.

3. When you are able to, hit MENU and then go up to TIMERS. Delete all of the record timers. Unplug it, reconnect the antenna, and plug it back in.

4. After a now a proper bootup, re-program you timers and you will be good to go.

5. And the best thing is, all of your pre-recorded shows will still be there on the hard drive.


I have 3 of these 7000pals and 2 have done this same thing, one of them did it twice. It seems like after years of adding and deleting timers, the DVR's software gets "confused". I've noticed twice it happened "on the hour" just as a program timer started while I was watching a program through the DVR. ZAP...Locked up! The power button would not even work to turn it off.

I would suggest that you do a yearly "TIMER CLEAN" to avoid this trouble in the future.

61 inch projection tv flashing on and off


The most common problem with JVC LCD rear projection TV is bulb failure. Do not panic, this is normal after 2-5 years of use.

You can change the complete assembly or for less cost just change the bulb. Do not use Osram or other funny brand "rebuilt" or locally made bulb. Use a Philips replacement and all should be good.

Changing the bulb involves removing the lamp assembly and taking it apart like a puzzle and replacing the bulb. JVC are a little more difficult to do than most others because the wires on the original bulb are molded into the glass on the original bulb. Wires must be cut and stripped of insulation before connecting to the new bulb.

All JVC LCD Rear projections TVs use TSCL110 TSCL110U TS-CL110U Lamps.

Hd channels are freezing up sound stays on just


Hey there, raeraekub! In order to assist you with this, I need to get a full understanding of the situation, so I'm going to ask you a few questions. First of all, is this issue still happening? If it is, try unplugging the receiver's power cord from the wall for 15 seconds then plugging it back in. If the problem continues, let me know what type of connection you have from the receiver to the TV. What type of TV do you have? With the DVR issue, is the freezing happening in the middle of watching a recording?

I belive the JVC hd-ila will only output digital audio when you are on a digital source. If you tune a digital channel on antenna or cable, it should work. If this doesn't work check all the settings, you may have a hardware failure. I personally would run the line directly from the hd dvr to the stereo and take out the middle man to keep your signal as true as possible.

Well first off i am assuming that your jvc ONLY has rf connections?
if so, the most you can do is go get an adaptor from walmart that has inputs for either svideo or components and output for rf.

JVC HD-52G786 shuts off


Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!
