Question about Hitachi 53UDX10B 53" Rear Projection Television
When I preform the magic focus the green will not focus properly. Do anyone have any ideas?
I posted this some time ago, but it is useful to your problem so here it goes:
It sounds like you convergence amplifiers are about to malfunction. If possible can you post a picture of what is happening. Again by the description you gave it sounds like the convergence amplifiers.
If you go to a shop the cost will about $400 - $500 (includes parts and labor).
If you do it yourself the cost will be about $25.00 - $50.00 (includes parts labor is free)
If you choose to do this yourself, here are the basic instructions:
1. Unplug the TV set
2. Take the rear bottom panel off
3. look for a large heat sink with two large black ICs (STK392-110) (6 sided components but rectangular in shape) on it, and remove the board the ICs are on from the TV set.
4. Unsolder the components using a soldering iron and a suction solder remover.
5. disconnect the components (ICs) from the heat sink
6. Unsolder all of the bias resistors and replace them with the proper values (usually 220, 150, 3.3, 2.2, and 3.9 ohms)
7. install the new ICs (STK392-110)
8. solder all connections IC and bias resistors
9. Inspect for shorts
10. reinstall circuit board
11. Plug the TV set in and turn it on.
Remember to check the deflection circuits also
I hope this helps
