With the Digital Lifestyles company out of business what do you do when your 42″ TV goes out? Fix it yourself! The LT42322 TV uses the TOM277CABB power supply board and is known to have power up issues after a few years of service. If you have one of these units that has no power, flashing power light and no picture, dim power light and no picture or takes several minutes to show a picture then this guide should help. We will show you how to rebuild the power supply board and bring the unit back to life. The following TVs were made by a company in California called Corion and they are out of business and no tech support is available:
All of the above models use the same power supply board, TOM277CABB.

We have repaired several of these units and every time it is capacitors in the power supply board that is causing the problem. Here is a picture of the TOM277CABB power supply board with the problem capacitors shown circled in yellow.

The capacitors to replace are as follows:
Board location C66, C64, C63, C71, C70 and C77 1000uf 25v
Board location C76, C74, C73, C75 470uf 35v

The original 1000uf capacitors were 16v but we have upgraded the parts in our repair kit to 25v because the 16v parts were causing the failures. Be sure to use good quality low ESR, high ripple current, high temp capacitors or you can damage the power supply board. More information on getting the correct capacitors can be found on our capacitor page.

We sell a repair kit with all of the proper value and size capacitors for $16.95 (free shipping) if you don’t want to worry about getting the correct parts.

This is not guaranteed to solve all problems but in most cases this is the issue with this model.

If you don’t want to do the repair yourself, use the service request link. Most monitor repairs run $40-45 plus return shipping, you can send the power supply board or the whole unit.

  2. Thank you! This TV has been sitting broken in my garage for over a year. I had already replaced the logic board to fix a frozen image, but then 8 months later the inverter went out. Starman sold a replacement for almost $200! I was waiting for something like this. I’ll give the capacitors a go, but I’m not that good at soldering. Its worth a shot!

  4. Had a tech at Radio Shack install the caps I bought from you but it did not work.
    Power light goes from red to green when I turn it on but still no picture.
    I have taken the back off several times to check all connections but no change occurred.
