Question about Toshiba 57H82 57" Rear Projection Television

2 Answers

My 57 inch Probjection Toshibi had the best picture. The problem with it now is tearing in the picture and wavy horizontal vertical lines. Problem is most prominent with DVDs. Initially the picture is unusable but eventually clears after about ten minutes. Also, problem is present on digital and high def channels.

    I have the same destorted picture for the first 5-10 minutes when the tv is turned on for the first time... The sound also takes a while to warm up and work. Now it takes about 10-20 minutes.. unfortunately I have no money to have it fixed and was hoping someone can help me do it myself. Unfortunately the economy is tight and so is my pockets. I would really appreciate the help. More than you'll ever know. This happened before and it was under warranty. I show the description for the fix was replaced hyper module, convergence, test unit. Hope this helps you.. I just need to know if I can actually change one on my own and HOW??

The hyper module is located in the metal box just behind the panel where all your cables plug into the tv. It is sodered to the board syou have to get under neath and melt the four places that the metal box is sodered. Once it's out you can either replace the whole board if you can find one. I can't seem to find it anywhere. you can also chage out all the 16v 10uf capacitors which is generally the source of the problem, but even these seem to be very difficult to locate now too.
Toshiba doesn't carry them anymore. Here is a link to the bulletin they put out becuase those capacitors are a known problem and failure point.

Toshiba hyper module. Vertical lines on screen.


change the 10 or so surface mounted bad filter caps in the Hyper module this set uses--the board is no longer available--it can be sent out for rebuild (not toshiba) but that is rather costly (200+)

is that wavy in vertical motion? and bending?  in that case maybe you have low voltage in your power inlet! or can you specify the color of wave and motion, if horizontal or vertical?

Start up problem


Bill;

Cause 1
1. VERTICAL ROLLING, VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE, ALSO MAY HAVE HORIZONTAL PULLING OR TEARING. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB.

2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
Replace all these if they look bad or not. If you can't do it yourself call a service Company and get an estimate, it should cost about $450 if they know what they are doing.
Thanks using FixYa, Big Irish.

About two months ago when we first turned on the TV there were wavy lines across the whole picture. When it warmed up they would go away. Now, the lines are there almost all the time and it's getting...


hi
You are experiencing a lack of vertical deflection or vertical collapse. Since it will come back the first thing I would suspect is “ring cracks” in the solder joint in the vertical circuit, mainly the vertical IC. These suspect solder joint can be re-soldered and the television set repaired.
I would suggest that you contact a local servicer. If you are repairing the set yourself, be careful, there is always a risk of shock when dealing with electronics.
OR
Check your equipment connections. Disconnect your equipment (VCR, DVD or set-top box) from the TV and reconnect, making sure each connection is in tight.

Picture Jumps/flashes for first 5 minutes


There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.
