Trying to order from Digi-Key . there are so many different types of 10uF 16V volts electrolytic capacitors. Surface mount? UD WT Series or low impedace hight temp?Please help!
Thanks

Get 10uf/16v radial lead 105 deg caps. Cut the leads short so they fit under the shield and give them a bend like the letter L when you solder them on the pads. These caps are easier to use than the original surface mounts and much better. Be very careful removing the old caps as not to lift the pads to which they are soldered. I will caution you that this job requires expert soldering skills and a good soldering tool with a fine tip. This is not a job for a novice. I know plenty of pros that botched hyper modules. Take note to observe polarity of the cap when installing. I don't know the part numbers off hand but you can Google "Toshiba hyper module kit" and find a list. I use an ESR meter and test for the bad caps. You will use about 7 or 8 so it is cheaper to order a pack of ten.

My 57h82 picture has picture noise in form of small jagged/wavy lines at edge of objects - particularly noticable for text or numbers. This appears on all channels and with all input sources. How to fix?


Is a common problem. Your hyperboard has failed. You can get a repair kit from www.TvRepairKits.com or buy a used hyperboard - but it will also fail someday unless it has been repaired with better parts than what the factory supplied.

When turned on, the screen has waves in it across the top and flickers. It is unreadable. When the TV warms up it seems to be better but is starting to flicker or flash all the time now.


Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

I suspect that it won't play any source that uses progressive scanning. The likely problem is the hyperboard or scaler board. This component allows the TV to switch from sandard definition TV to HD. Typically, the hyperboard will cause shaking and wiggly images especialy noticeable at the top of the screen. It will generally work better the longer its on. Expect to spend $400-500 to resolve this.
