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.

Horizontal lines across screen picture going fuzzy in and out and then no picture at all


A horizontal line that rolls from the bottom to the top of the tv could be a Hum Bar. This is from a bad ground either for the house electric system or for the cable system. By code, these grounds are supposed to be connected (bonded) together. In other words, the electrical interference is going through your tv instead of into the ground. Fuzzy picture is usually from low cable signal. This can be due to bad cables, connections, or splitters or problems outside with the drop (cable line outside that runs to the house). Splitters, by design, lower the cable signal (i.e. a 2 way splitter cuts the signal in half). If you have unnecessary splitters you should remove them. If you have more than about 6 or 7 tvs, you may need to add an amplifier.

My son was bouncing a small ball against the screen and then it went to looking like a rainbow. Would this be the picture tube?


He may have caused some type of damage to the picture tube, but usually rainbow effects happen when magnets are present. Perhaps the ball became charged with a large amount of static, which then discharged across the tube, damaging the controlling circuits.

No picture.Just a single line in middle of screen.


No, your picture tube is fine. This is a problem in the vertical circuit that deflects the beam up and down. This repair is fairly typical across most television brands and should not cost too much to fix. I don't want to quote another shops pricing but from us this would run about $150.00 to fix.

Has fuzzy spots all the way across the screen and just scrolls up


Is the picture fuzzy whether you are waching tv or a dvd or a tape. If it's only fuzzy on tv or dvd or tape then it's the source. If all inputs are fuzzy suspect a bad tv.

Ghosting of picture from a Panasonic home cinema system


There must be a fault in the screening of the internal wiring to the scart outlet in the home theatre system. I simply changed the way the player was connected to the TV and the interference disappeared:-

1.) I used the RCA video outlet instead of the scart lead. Picture quality was not compromised. FYI the Panasonic Plasma TV I have has only RGB video input sockets at the back, so I used a scart to RCA adaptor to overcome this problem of connecting old technology to new.

2.) The surround sound when playing DVDs is generated directly from the home theatre system so there was no need to connect the audio from the home theatre system to the TV

3.) I used a pair of RCA leads to connect the "audio out" from the TV to the "audio in"on the home theatre system to provide the option of TV sound through the home theatre system.

Picture on RCA TV shrinks to a horizontal line


Hello,
Sounds to me you have a cold solder joint ( loose solder connection ) on the printer circuit board around or on the vertical chip or on one of the vertical capacitors. You may also have a bad vertical chip or a bad vertical capacitor, but I doubt it since it did come and go. I'de get a soldering iron and some solder and touch up the connections. I will remind you that you need to always excersise saftey by making sure, before removing the back, unplug the TV from the wall, and use care not to come in contact with the large red wire going to the back of the picture tube as the picture tube can be turned off and still store lots of voltage ( up to 35,000 volts). Always stay safe and when soldering, use care not to run solder across places that will make a short.
Good Luck and I hope this helps

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.
