I have a LE49A509 Hitachi Television that will turn on but the screen is black. At least the blue light comes on and stays on but no picture at all. What is wrong and how can I fix it

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

The IPboard part no. BN44-0012A is bad. We had to replace 5 monitors with the same problem. If under warranty call 1-800-Samsung for repair or exchange.

There is a post by Stivo on this board that has helped many fix this type of problem. There are two capacitors on the power supply board that go bad and if replaced can fix this problem . The parts can be purchased at your local Radio Shack for about five dollars or less. I just did it today and it worked!!!
