The red power light on the front of my 57h81 Blicks but there seems to be no code. when you hit the power button it will display a steady light then begin to blink with no code. i can't find a fuse and it acts like it wants to turn on then the light starts flashing.
This sounds like the typical toshiba power regulator ic fault. it begins with an str##### Its not something a handyman should try to tackle. It should be repaired by a quilified repair person Sorry Good Luck

Hello Guru. I am getting the same error as ronny. My Toshiba has the TOUCH FOCUS ERROR message and the blue lines do not converge. I see a resolution was posted to replace the convergence IC's and that the Low OHM Resistors need to be checked for proper value.
Can you tell me how to do that? Thanks...

My 57H81 won't converge, plus I get the "touch focus error" message. I could get manual convergence of blue, but not red. Plus, during touch focus the red would not move horizontally

I have a Toshiba 57" DLP Projection TV Model # 57H82 that has a fuzzy picture. It recently developed a blurry picture.The picture corrects after I shut it off for a couple of minutes then turn it back on but then resumes to the fuzzy/blurry state after half an hour of running. Also the audio went out as well. It seems to me that something shorted in the main pcb board but I'm not sure. Anyone knows how to fix this.
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?

hyper board removal procedure and location
Hyper board is located directly behind the input board, this is where all the tv conections are, then they are two tabs soldered from the bottom of the board then it simply unplugs, But replacing all those capacitors on that board can be a little tricky, replace all 10up @16volt caps and that usaly repairs the board

I have a toshiba 57H81, the menu picture is clear but the tv picture is all fuzzy and distorted. What can that ba and how can i fix it? also I need the service manual.
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

I'm trying to manually fix color convergence on my Toshiba 57H81 tv but the blue cross will not move in order to line up with green. Red cross moves fine. What can I do?
I tried Touch Focus but it comes back "Touch Focus Error"
The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

When we turn on the TV the picture is very fuzzy, colour still seems ok. It gradually "warms up" and the fuzziness reduces over a few minutes until the picture is pretty much back to normal. (TV Model is 57VW9UA Rear Pro 1080i HD TV)
Very common problem. not a common or easy fix though. This is known as a faulty "hypermodule" The hypemodule is a cuircit board that processes the signal. At the shop i have repaired a few a these on average 2 a month. The ideal situation is to replace this cuicit board. However this was such a common occurance these boards became rare. very hard to locate. So toshiba gave service centers another option a way to repair these. It however evolves the replacement of 11 very small micro capacitors. Only the most experence tech's experenced in surface mounted soldering should attempt this repair. You can easly mess this board up and once messed up...like i said you cant find them. My best advice is to find you a qualified shop who has done this repair before. It take an experence tech around 3 to 4 hours with magnifing glass and twezzers. My shop generally charges about 300 for this repair but shops vary based on experence
