How do I upgrade my LG LH 20 lcd tv firmware


As far as I can see on the support page, here: Product Support
there is no firmware upgrade. An upgrade is only made, when several people have a issue with there device, and it can be solved by upgrading the firmware. Ir is NO SOLUTION for real defects.
You even can't upgrade if the device is not working correct.
It needs to run a short program, put is a small part of the RAM, and during the upgrade it can't lose power, because the little program has to flash (put new software in) the electrical erasable memory.
When something goes wrong during the update, nothing works and you need to visit a service centre to put things right.
As long as your TV works fine, don't update. When LG really does have an update, they will email all registered owners and carefully explain how to do the upgrade.
To be sure about any updates, register your TV on the support site.
When you have a problem with the TV contact LG or a certified repair centre close to you.
It would not be wise to try to change something on your TV, as long as you are not 100% sure it would improve the TV.

How to do a firmware update


Contact LG and unless absolutely needed do not upgrade just to upgrade--seen a lot of sets where it makes matters much worse.

LG should know if upgrades are available and what the reasons for them are.....

I've checked the LG support website. The product is discontinued but if you register your product you may get downloads of firmware upgrades, etc. With my phillips I couldn't see any firmware upgrades until I registered my product. Register here!

i have had this same problem with many of my customers of late...have not found and hard and fast solution however try retuning the tv or upgrading the firmware. I think you may have to contact LG regarding a firmware upgrade as this tv has no network connections or usb ports. i had to replace a set top box for a newer model for this same reason.

Invalid format error with P1600 blu-ray and LG LCD TV 42"


It may be a firmware issue if hdmi works with other items such as playstation.
If no hdmi the main Pcb hdmi ports are bad and the main Pcb would have to be replaced.

Consumers cannot upgrade the firmware so a shop would be the only option.
