Toshiba 50H12 Rear Projection TV wavy screen

Hi, so here is the problem, I hope you can help. For a little while when I would first turn on the TV the screen was very wavy and distorted. After letting it warm up for a little while the picture was fine. However, the problem has only gotten worse now and no matter how long you let the TV warm up for, the picture does not get any better. The weird thing is when we hook up the TV thru the component hookup, the picture is still a little wavy at first but then after it warms up, it is fine. I have no idea what I need to do...I am a single mom with two kids and can not afford to hire a repair tech if I really don't have too!! Any help would be greatly appriciated.
Thanks in advance!!

    Nice comment, but not a great solution to my current problem.

    We have exactly the same problem/same model. It started only when I played a DVD. It has gotten worse over time. Now the TV picture is starting to go bad, too. a repair guy charged 90.$ to look at it , then told us 2 weeks and 475.00$ to fix it. Pretty rotten deal for an expensive 4year old TV that cost so much. Won't be buying another Toshiba- that much I know. Haven't had it repaired yet- not sure what to do. Mite give up TV!

    Same problem here, HD channels show up ok but getting worse, if anyone has a fix let me know

  • nateroo Oct 06, 2008

    I have the same problem...looks like someone mounted a ******** on the projector...If I turn off the tv, it would take 15mins for the wavy jitters to go away. so I left it on all the time....now it doesn't go away at all...drivin' me NUTS!! scared to get it serviced because of the potential cost. I have a call in to some local repair shops to find out their insight on this model/problem. If it's decent, I'll post it here! Hard to figure out what to buy these days...even name brands like Sony have dumped on me. Always a gamble!!

    I have the same problem. Only mine is not wavy when I turn to the HD channels. Every other channel is wavy, even my DVD's are wavy when I watch them.

    I hope someone out there can help.

    My set has same trouble. Only four years old. A friend who was in TV repair for twenty years diagnosed over the phone for me. Said it was either a bad capacitor on the horizontal sweep circuit or a bad fly back transformer... Paid $99.00 for a repair tech to check it out. Found ruptured capacitor on main deflection board (pd0074a)... Replacement boards no longer available... Must have board rebuilt. cost $531.00... Board came back from re-builder untouched. Sent back second time... I am still waiting... I bought this set because my last Toshiba lasted twenty two years... I guess those days are long gone...

    Good luck!!!

There is a Hyper Module mounted right behind the video inputs board. in most cases you can replace the 10uf surface mounts carefully not to tear the foil. and the set will return to normal. or replace the H/M board. this board is soldered 4 tabs on bottom of main board and then pulls out. good luck list of caps cz52(may not have this cap).. cx261 cx270 cx230 cx178 c514 cx221 cx250 cx241 cx541 cx670

Wavy lines appear across the screen


Projection TV sets have two very common problems listed below.

Problem #1) 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

Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Hitachi C50-FD2000 Screen Distorted


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.

Horizonal- picture is wavy


i have the same problem.  i know it involves changing the Aspect.  there is an Aspect button on the remote which does not work for me, but could for you?  also, after pressing the menu button, some options come onto the screen and i used to be able to get to Aspect that way also, and now i can't.  i hope you can!  if not, do we need a manual for it?  good luck.

Wavy or distorted monitor


Wavy or distorted issues only arise if electronics or anything that has magnets in it is near it or on the CRT ( the really huge monitors) so try moving it elsewhere ( In this case you can hire someone with the "magic wand " to zapp the colours back)(general tv repairer.If its an LCD (flat and small screen) it may be dying as the transistors are wearing out ( They usually last for 4 yrs) The only thing you can do is replace the circuit board or the panel . If you have another pc or laptop try to connect it to the monitor and if the pictures are perfect ,its your graphics card .

The best solution to this is to move the screen to another place without electronics or to connect it to a laptop or pc to see if its ok. If the symptoms persist i recommend you to buy another perferably dell screens 19" Lcd as they are cheap and provide good quality.

Sorry for the huge legnth of this Hope it helps :)

Distorting


if it is wavy lines across the top it is probably the scan converter/ hyper bd they are becoming hard to find/expensive you can repair them but it requires many surface mounted capacitors and requires some VERY skilled soldering.
