I almost replaced it, but I fixed it instead, saving hundreds.

32dt1u Sourced from Toshiba

My TV started to drop video. When the issue would arise the TV behaved as if the coaxial cable was unplugged. The behavior was the same across all inputs. My first thought was to simply buy a new TV. That turned out to be an expensive option. I was ready to buy a unit from a local store, but they did not the unit I wanted in stock. So my thoughts moved onto to the idea of attempting to fix it.

A search online did not reveal a true fix it guide. But the search did lead to a few forum posts that lead me to believe I could fix the problem with a replacement main board. Since I could not find guide, I present to you a new guide to fix an older TV.



My TV is a Toshiba 32 inch LCD model 32DT1U. It was made around 2010. When I was shopping for a TV I looking for something that could handle multiple inputs. This fit the bill the with support for RCA, a couple of HDMI ports, and even a VGA port for the PC. But if none of those ports work it, is not much use. So with about an hour of total time, a Philips head screw driver and less than a 100 dollars, you too can fix your TV.

Diagnose: about 20 minutes.

Error Message

The first step is to diagnose the issue. In my case, I had a working display, and I could navigate the system menus. This indicated that the driver board, LCD panel, and the controller were all working. The lack of video input lead me to believe that the main board had the issue. The intermittent behavior lead me to believe that the issue is probably a crack in a solder joint. I had two choices, attempt to fix the main board, or replace it. I decided it was easier, faster, and cheaper to replace it.

Order the parts: about 20 minutes.

Main Board

A few searches for the TV model main board revealed the part number of the main board. I then used that part number to look on the popular commerce sites. In no time I had selected a reputable supplier, placed the order and waited for the package to show up at my door a few days later. A note of caution, make sure you do your homework. Cross reference the part number and model. For my TV their appeared to be a very similar model that had a main board that could have worked with my model. A little more research revealed that the board only have a 50/50 chance of working with my model and seemed to depend when the model produced. I did a little more searching to find a board guaranteed to work with my model. So before you click the buy button, doubt check that the part is what you really need.

Open the TV

Back panel removed

Once the part arrived a few days later, it was time to do the surgery: about 20 minutes.

Safety first, unplug the TV from the wall. Locate the screws around the back of the TV. This unit had 3 different types of screws, but thankfully none of them were hidden, under stickers, or hard to get to.

Check the Power Supply board

Remove the back panel from the TV. Check that there is no stray voltage in the system, discharge it if need be. I did not have any, so I could move on with out worry. The main board is easy to access. With 4 screws and few cable connectors, the old board is quick to remove.

Swap the board

Main board with cables disconnected

Take the new board out it’s packaging. Be careful when handling as to not zap the board with a static charge. Place the new board in the location, testing the button actuation and making sure everything is lined up. Screw the board in place and reconnect the cables.


Don't forget these screws.

Place the back panel onto the TV and screw it in place. The TV should now appear as it did before the start of this exercise.

Test it

TV rebuilt with old board

Plug the TV power cord into an outlet. Power the unit on. The TV should display that no video input detected. Cycle through the menus, make sure everything appears as it should. In my case I had to select English as the default language. Next plug a video source in, and select that video source as the active the input. You should see the video appear on the display. Plug any other video source you have and confirm that they work as well. If you do not have a successful display, unplug the TV power cord, remove the back panel and check your cable connections to the main board. If you still do not have a working TV, contact the board supplier.

Final thoughts

I was ready to spend $250 or more on a new TV. But deciding to fix this for less than $60 turned out to be a great money saver. I think I’ll take the money I had budgeted for a new TV and put it into a TV enhancement like a Roku, or Amazon Fire. I will still come out head. These steps worked for me in my situation, your mileage may vary.

For my first post, I will give a brief introduction of myself. I own a small technology company that started with PLC programming, and has progressed to software testing and quality assurance. Along the way I have performed tasks in mechanical and electrical design, CAD, CAM,  system integrations, automation, motion control, simulators, SCADA, CNC, and network management. Currently I perform contract work for Microsoft, in the Windows Embedded Compact 7 setup team. There was a learning curve involved with setup the team as it uses WIX, MSIEXEC, C#, C++, HTML, as well a number of other tools. As team setup, we have a main focus of Windows Embedded Compact 7 software installation. However we also support several other customers.
This blog’s focus will begin on the offerings of WindowsEmbeddedCompact7.exe. Primarily the focus will be on the installation and maintenance of the software. The next blog will explain update process the user will experience when using the software. Other points on the software will be explained in future posts. Other topics may also arise such as: PLC programming, CNC machines, and possibly a UAV side project. I welcome questions; I will answer them to the best of my ability.
Thank you for reading.
