Question about Toshiba 52HMX84 52" Rear Projection HDTV-Ready Television

1 Answer

When initially turned on the picture jumps around for several minutes

It looks like a cable channel you don't get. the audio also cuts out at the same time. 'Fonzie'-ing it sometimes helps and the problem generally goes away within 20 minutes. yes, it's 2008 and i have to wait for my tv to 'warm up' for 20 minutes.

"Fonzie-ing it" ? It's terrible that I understood what that meant. lol

Sounds like the tuner has a bad solder joint. You may need a Repairman.

I cant turn my tv or set on channel 4

if the box and the TV both have audio/video jacks---hook from the outputs on the box and connect to one on the set---leave set on that input and used box to change channels===most cable remotes can be also programmed to shut the tv on/off and control audio.

Get around the issue and besides you will get a better picture that way.

If you can't figure it out the cable company usually can and will.

First: an old adage with TV sets of all kinds is the set is not smart enough to know what channel you are on---problems only on a few channels usually are not the set.

The only place where this is not the case is a group of several adjacent channels like 2-6 having this could mean a problem with the low band in the set's tuner--a bad tuner.

Most of these large Mitsubishi sets have PIP or picture in picture--the remote will have a swap button--engage it and see if the PIP has the same issue----if not the set uses 2 tuners and one is bad.

A cable box would allow you to instantly get around that by going into the rear audio/video jacks.

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.

No picture or sound but get channel and clock on screen display


Initially, suspect would be your audio/video sources such as the DVD, Home Theater, Cable box, Satellite Receiver. Pls check the cables/wirings or how they are attached to the PTV. If the PTV is connected directly to a cable provider with the this issue, then it is either your cable provider's signal is not reaching you or the PTV's tuner section needs to be looked up.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
