Question about Polaroid Televison & Video
When i try to change the channel it freezes on the channel and goes to a black screen.And only one channel works because it was the last channel i was watching before it broke.
Hello, it sounds like the main board has gone bad (the tuner is mounted on the main board). The cost of the board replacement may be close to the cost of a new set. You may want to explore that option....tks....Terry

My sister-in-law has exactly the same problem and is a common one with this unit.
I've spoken to a technician who says that:
1. Hitachi are withdrawing from Australia and there are VERY limited service centres left
2. The problem is a chip on the main board and depending when the TV was made will determine whether the chip is a plu-in or soldered on to the main board - if it's the latter, you'll be up for a main board at around $400
3. He couldn't get the price of the plug-in chip because he couldn't get through to Hitachi.

You may be able to program your cable box remote to control your TV in addition to your cable box. When they initially set up your cable box they probably left a pamphlet giving you instructions on how to program your remote. I'm not sure why you can't change the TV channels manually but this may give you a work-around.

i had the same problem. i opened the panel in the back of the tv (3 screws) and opened the aluminum panel (3 screws). there's a red led light located at the bottom left corner of the top board. to the right of the led light, you will find this thing with 4 switches. i turned the two bottom switches "burn" and "epmw" to on. so far tv have been working.

sounds like inverter board. What it sounds like is happing is your LCD is working ut the backligkt board that allows you to see is kicking off. (as you still have sound) Which could be the (most likely) inverter board, or the power supply board. You can take apart and check for voltage at your power supply. The power supply has a pigtail with large white wires and a connector. Power up with the center back cover off and check your voltage at the white connector on the power supply before and after the screen gos out. If there is no large voltage loss it is your inverter board.
You can used boards on e-bay or
