Question about Toshiba 65H81 65" Rear Projection Television

1 Answer

TV took a dump

While trying to watch anything, the picture is very dark, fuzzy, and mostly red. I checked various sources (digital cable HD, digital cable standard, VCR coax, DVD component & s-video) For anyone familiar with the blue background and graphics on the typical Sony DVD player, it shows up as a dark blue background, with extremely fuzzy text & graphics.

What's interesting is when I pull up the TV setup menu, the text is clear and all the colors are normal on the icons. For kicks, I checked the convergence menu, and the crosses (red, blue, green) appear normal, and even let me do the convergence.

Please help!

Why my jvc television hd61z456 not showing in high definition

What is the signal source that you are watching on your HD61Z456?
The problem you describe usually happens when you aren't using an HD source or have downgraded the signal by the composite input on your TV. (Composite cables only support 480i SD signals.)

You will only see 720p HD content from HD sources, if you use HD compatible inputs. Some OTA channels are also broadcast as only analog signals (usually the -2 and higher sub-channels). If you have cable or satellite, make sure that you have the HD programming and have tuned to the HD version of the channel.

The HDMI and component inputs both support HD signals.

I hope this helps. If you are watching an HD source and the problem persists, I recommend trying new video cables. Next, check if you are getting interference from your devices by using a cable with a Ferrite core. See for HDMI cables with Ferrite cores. The cores help block interference. If you have very long cable runs, check the behavior with shorter cables between the source and the TV.

JVC HD-56FN97 when turned on blue light is solid,red ligt blinks a few times and goes out. My picture is very dark despite adjustments I make in the menu, any help or feed back apreciated.

The set does use a lamp for a light source and average life is 2 years or 2000 hours---many lamps before they actually fail get to be darker.

I have a phillip magnavox big screen tv it works fine but the color is too dark i think i need a picture tube

If its the one indicated here or one like it :

The picture tube type (CRT) rear projection tubes require annual cleaning.

With set off and back removed locate the three large black lens atop the chassis--hard to miss them.

The are the red, green, and blue tubes and are your light source for the picture---------if dark and they are dirty or dusty the picture will be darker and not as sharp or clear as it once was..

spray some glass cleaner on a paper towel and wipe them clean.

Do not touch anything else in set and do it with set unplugged.

put back cover on and see if picture is noticeably improved; if so do it once a year or more if in a dusty place.

Let me know if you have questions.

I have picture but no sound. We just had our surround sound system go out and are trying to run our tv on it's own internal speaker system. How do you hook it to our direct tv hd box


You need to use audio cables. Connect two red and white audio cables from the output on the HD box to the relative input at the back of TV (nr.4 in picture below). The best way to connect the HD box is by using component cables, that are the red-green and blue trio of cables, plus a white and red audio cables.

Here what you need:

Three plus two:
Component Video Cable
Audio Red / White Cable

or single set of five:
Cables Unlimited - Video / audio cable

Once you have the five cables, connect them to the output at the back of the Direct TV box, and then connect the other end of the cable to either group of connectors 6, or to one of the columns in connector 7. Do connection with box and TV power off. After re-applying power use the source-input selector on remote to select the source from Direct TV box.

When I turn on the TV, the picture is fuzzy. After five minutes, the picture is clear but any words are out of focus even the menu for adjustments is out of focus. The convergence for red is clear but...


Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

Blurry picture

In the store they use an HD source and connection. Is your cable box HD? It will have component or hdmi connections if it is.You have use either one to get HD everything else will be SD(standard def).And you have to be on an HD channel.Digital cable refers to how the signal is delivered doesn't mean its HD. SD channels on digital still look bad..

My HD only works on my video setting, but I have no sound

Ok so the sound is fine on all of the other sources,
The component is running from the cable box to the amp, and you can see it.
just take the audio Red/Whit RCA out of the cable box, and input it to Cable/TV or whatever its labled, Red White, RCA.

If you want surround, then you will have to go Coaxial((single orange RCA) or TOS out of the cable box to the Digital input on the AMP. When you use this instead of Red White RCA, your amp will automatically switch between the different types of surround depending on what the source calls for or is encoded in.

You may have to get into the amps menu and change that amps input to Digital/Coax/TOS for the surround sound.

Any more specific questions, I need the model #s.

50HDX82 rear projection Flicker/Fuzzy and Vertical Purple Lines

The hyper module itself is not an expensive repair about $70 to $100.00 dollars. The tech will simply be replacing about a dozen 16v/10mf smd caps and re-installing it on the signal board. But that doesn't address what he has to do to get to it and get the hyper board off and back on the signal board and that is a bit time consuming.
What I would suggest is to call around to the various shops and ask what they charge for the hyper module repair and see if you can get an off the cuff estimate for around $250.00 dollars.
If you need help finding some reputable shops try for help in finding some of the best technicians available.

Mitsubishi WD-52631 shadows and blurs in dark lit movies

If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.
