I have a Jumbo universal remote by Innovage and I need the programing codes for the tv. Do you have them???


To program your remote by entering a code from a manufacturer's list, follow these steps:

  1. Turn on your TV.
  2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
  3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
  4. Enter the first set of 3-digit codes from the list. The LED will blink once every keypress. After the 3rd digit, the red LED will turn off indicating that the code was recognized for the device. If the code was not compatible, the LED will flash several times and you need to return to step 2 to try that code again or to try the next code in the list.
  5. After the LED has turned off, aim the remote at the TV and press ON/OFF. If the device turns off, you have used the correct code and the remote was successfully programed. If the device does not power off, return to step 2 and try again with the next code in the list.


To have the remote try each TV code it knows one at a time, follow these steps:
  1. Turn on your TV.
  2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
  3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
  4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
  5. Once the TV turns off, press the ENTER button to store the code and the LED will turn off.

I hope that helps.

HITACHI 60UX58B



If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

Hitachi 60"(60sbx78b) Will not power on, fuse still good.


Matt, Hitachi`s have a series of green LED`s and one red LED on the main board, un-plug the tv for 30 seconds and then with the back cover removed plug the set back in and watch the led`s while someone else turns on the set, usually the led`s will temporarily light then one or more will immediately go out and then the rest will slowly go out and the red one will then start blinking, each led is a power supply indicator, 130 volt, 12 volt, 5 volt etcetera, find out which one(s) going out first and get back to me, BMW Rider

No Picture no sound on a Hitachi Rear Projection


if the 120v never comes up, check e994 as it is probably open, and either the blue horizontal retrace cap infront of the h-out transistor is burnt/shorted or transistor could be.
