Question about Toshiba 50H72 50" Rear Projection Television

1 Answer

Ratio issues Hello, I came home the other day, the tv was on but it was a white screen with specifications information on it. I turned the tv off and then turned it back on and it came on. The problem is that know when on HD1 or HD 2 there are bars on the side and we are not able to turn on the closed captioning, even though it says it is on. I can change the view put I can not get the captioning on. I can change to video 1 and I get full screen and closed captioning but I can not use the cable directory. Any advise is welcome. We really need to have closed captioning. Thanks

My picture is distorted ,sound is good but i also have vertical waves on sides also picture runs out of both sides like aspect ratio is out ,it is set at 4.3 is this still a convergence issue or something...

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

TV picture goes out after 10 minutes of viewing with popping sound

It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.

After 5-10 minutes screen turns completly red/orange

Hello Fixya customer,

Although it would be helpful to be model specific, I can point to some general areas of concern.

If the screen is turning red with White slanting lines, that is an indication of a faulty color dirve circuit or red CRT. Please supply the model number so that I may give you product specific information.

Thank you for using Fixya, and I look forward to your response.

Screen turn green tv is 57 rear projection

Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

Color flickers on and off

I went to the Sony support page for your model.(link below)
They are undergoing maintenance right now, so I couldn't find any answers for you. I would check back with the website to see if they can help you. If the Standby timer light flashes, you may need to have the TV repaired. There is a "Hot Topics" section for "How to troubleshoot television picture issues" that will probably be very helpful to you.

Your hitachi tv problem....

Sorry I can not help. I had to work that day. My wife was home and she told me he went into some kind of service or maintenance menu on the TV by pressing some button combination. Again, sorry I can not help you. I can give you the information of the company if you want to call them.

I have a 27''orion.It was raining,thundering 1 day last week and the T.V was on.All of a sudden the lights went out,and when they came back on,I cut the t.v back on and there was a white streak going...

You have a power supply issue on the main board of your set. This is not an easy fix for a home owner, Your best bet is to call a service shop and get a price quote. Tearing into tv's is very dangerous! High voltage is present even when unplugged! Good luck!

Sony kp-53hs30 projection tv

Good Day,
It sounds like your TV is experiencing a convergence problem. You should contact a Sony Authorized Service Center and have them come out to your home and give an estimate before they proceed with the repairs on your 2001, $1,900.00 TV.
Good Luck, big IRISH.
