Question about Toshiba 50H72 50" Rear Projection Television

1 Answer

Picture gone. I have a Toshiba 50H72 rare projection TV and face the same problem now. Two weeks ago, I found that the letters or pictures at left bottom of TV became two line or ghosted that always red color was out of alignment. I was told that I could try align the convergence.So I opened front and adjusted the convergence. I did not see big improvement. This morning, I just tried to adjust it again. Unfortunately, all of sudden, picture was gone. I tried to torn off and on directtv satellite and TV several times. The TV light and sound were OK but there was no picture at all. Is anyone can help me to figure out what could be the reasons and I am wondering how much it could cost to fix this problem?

    I have a Toshiba TheaterView but really do not know the model ( i cannot find the model number ?) Now let me describe the unit, it stands 50" tall, the dia measurement is also 50". Black wood frame, flat front.
    I bought this unit at a yard sale for $ 5.00 (get what u pay for right ) it was working, played with it, went into the convergence setup, (maybe i messed up here, not knowing what i was doing) worked for several days, the picture went out, unplugged it, after 24 hours the picture came back in. Then turned it off with remote, day later turned it back on NO PICTURE, but there is sound, even went into the channel setup, again sound galore, but no video. so i took off the plastic front, looked at the three ( R G B ) colour guns, the red, green guns are very bright, but the blue (far right gun) is very faint, can anyone tell me what i did wrong, if anything, or is it in the hardware ?

Power but no picture


the Y-SUS BOARD is for picture in tv.if the picture is not coming or not proper the Y-SUS board needs replacing .but if the picture is blurry or with linings reparing helps.but in your case the tv does not turns on with y-sus board connected only error led comes on.this means y-sus board needs replacement.
you can get it from www.partstore.com
---------
if you are not familiar with replacing the y-sus board its advisable to get it done by local tv repair technician familiar with your brand/model.

This will help. Thanks please keep updated.please do rate the solution if helped.thank you for using fixya.

Projection sets have two very common problems.

The first common problem is convergence


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 more information and a DIY convergenece repair kit with instructions from the link below.

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

*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

Tv picture


Does the image appear to be 3D? Let me know as it sounds like convergence issues. Is there anyway you can post a picture of what the screen looks like?

Flashing picture when start up


What i would do id purchase a can of freeze from radio shack
wait till the picture is good then freeze one ic at a time till the problem shows up, once it shows up let it warm back up and refreeze to make sure you got the correct part.
found this on anther site:
My first guess is an electrolytic cap in the main power supply and/or a voltage regulator that feeds the deflection amplifiers.

The cost of repair is not much; the greatest challenge is finding the bad cap because there are so many of them and scattered through out the sections.

If you have a scope and can look at some waveforms and voltages around the deflection and power supply feeds you may be able to zero in on it right away
