The thin line indicates that there is no vertical. This is usually controlled by a single IC (vertical IC). Look for a small flat IC attached to a heat sink with 9-14 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC with a new one.

Why is my tv jvc hd70zr7j showing a blank black screen when i connect the hdmi signal cable? the ps3 used to work fine before but since i moved into a new place it just shows the black screen


you have a HDMI port Failure that's not uncommon many people fail to turn the units off before switching cables around it only takes a momentary short on the 5 volt line to one of the other lines and it can short it . or it may just be a normal failure . but you would have to change the .with the AV and HDMI ports on it to restore operation . your set probably has more then one port ? have you tried the others . by process of elimination you have ruled out its the game and cables so it points back to the tv

Common Projection TV Problems and Fixes


In this article we will will outline some of the most common projection TV problems, fixes, pros and cons, and average lifespan.
Average Lifespan: 7-20 YearsPros: Large screen size and excellent picture quality. Some model support HD. Very reliable when they are cared for.
Cons: Heavier and bulkier than the newer plasma or LCD sets so if you live in a cardboard box it may take up a bit more room.
Common Problems/Fixes
Common Problem #1 - Convergence: One the most common problems that you will run into eventually is a convergence failure. This is when the TV colors do not align anymore and the TV will look 3D, warped or distorted. This is a very common problem and a fairly simple DIY fix. Parts to repair this can be found over the internet from sites such as www.TvRepairKits.com . Below are a few photos of a typical convergence problem and a link to a video on YouTube with more details.

Notice how the image looks 3D...this is a classic example of a convergence failure...it may also look warped or have a wave look. But the wave will not fluctuate.

Common Problem #2 - Dull or Dark Video
The second most common problem we see on projection TV sets is whats known as the dull video issue. This is commonly caused by discolored cooling fluid in the lenses. Over many years - usually around 5-7 years - the fluid will discolor and cause the video to wash out or look dull. Changing the CRT fluid out every 7-10 years will restore the image clarity back to factory new conditions. You will actually be amazed at how sharp and clear the video looks once a fluid repair has been done.
Here is a before and after photo notice how it looks washed out. In some cases the images will look like they have halos around them or the screen will have a reddish tint. Bottom line - if your projection TV has never had the lens fluid replaced the video is not as sharp as it can be. You can get fluid kits from the same sites mentioned above. Doing this repair yourself or through a shop will make the video look amazing.

Common Problem #3 - Dead set with no videoIn these cases there can be more than one common issue depending on the TV brand and model. But to make things simple if the TV has no audio or video and its making a constant chirping sound the issue is caused by a short in the convergence. The fix is to do a convergence repair. If however its not chirping constantly it can be one of many issue from failed capacitors, diodes, flybacks, etc.

I have a hitachi 46f500 projection tv will not work on my new dital antenna


can you explain please. also check the aerial cable use a meter and check that the Arial is wired in right . as sometime it will be down to the Arial than the tv. even a thin peace of the coax cable may be touching the live in the Arial this will make you not get a signal. if the tv was fine before then i would say the arial wire is the fault.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

JVC Interiart 32" Digital TV. No longer turns on. Has a thin horizontal line across screen when TV is on. No picture.


The thin line indicates that there is no vertical. This is usually controlled by a single IC (vertical IC). Look for a small flat IC attached to a heat sink with 9-14 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC with a new one.
