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 TVrepairpros.com for help in finding some of the best technicians available.

I have a Toshiba HD LCD tV, model 37AV50U. the screen is black. I still get audio and can change the channels but the screen stays black. It doesn't even show the menu box. Is this something I can fix myself?

Fuzzy/ distorted tv pic


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

Bad picturre on toshiba tv


Good Day, pieps57;

Corrective Action: Remove the MVUP13 Hyper Module from the TV chassis, remove the top shield and replace the 10uf, 16v capacitors using Part Number 24619040. It’s recommended that all of the capacitors identified be replaced (Note: These capacitors are low impedance surface mounted aluminum electrolytic capacitors. Care should be taken to avoid damaging the PCB while replacing these capacitors.) CAPS: cx178, cx221, cx230, cx241, cx250, cx261, cx270, cx541, cx670 & c514, c5030.
Good Luck, Big Irish.

You likely have a bad hyper board.  As time goes on the lenght of time it takes to get a clear picture will increase and eventually the picture will never clear up untill the part is either repaired or replaced.
