Question about Hitachi 53UDX10B 53" Rear Projection Television
I have a Hitachi 53UDX10B and when I try to turn on the power button flashes and a chirping noise comes from the back. If I let it continue to cycle like that I cannot make it stop until I unplug the tv. I opened up the back and tried again. I noticed several LEDs lite or flashing. Here is what I found. DP11 and DP35 flash. DP23, DP37, and DP06 (red) stay solid. I've readd several posts about convergance. Please help. I would love to avoid a costly repair.
The chirping is most likely the ballast trying to fire the lamp. Most likely you should replace the ballast and the three lamps and the problem should be fixed. If you check the lamps and ballast and find that one looks like it is the problem, first try replacing just that one but if you are going to replace one why not all? Replacing them shouldn't be too hard if you are good with simple tools and that should fix the problem. Let me know if you have any questions and I would be glad to help.
Thank you for using Fixya and Good Luck

The convergence issue might not affect the TV to the point of not turning ON.
The chirping noise you hear, it means there is a short circuit in the circuitry, possible the HOT or power supply assembly.
