1. YOUR flyback is going bad 2. Peform a removal and replacement 3. check your error codes first to ensue nothing else exists 4. Proceed to change out the required parts 5. Observe all electrical risks 6. Order replacements from jimmyparts.com 7. Ensure to always remove power 8. Ensure to always use electrostatic wrist strap
Generally what occurs is the units soldered connections on the main projection board warm up as the system warms up. Thus, the loose capacitors, resisters, and diodes are causing the CHANGE when the system warms up. When metal contracts, it expands thus losing the connection needed for a solid connection. This process is normal after the units have reached their service life. Keep in mind that you can repair this but at the expense of time if you have never performed this type of work.

How can i fix my hitachi


Sounds like LOT fault [shorted winding]. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.

Buzzing Noise and TV picture is yellow


Andy, I'm thinking the buzz is from the deflection coil (yoke) on the neck of the tube or the power supply. Probably not the high voltage as you can hear the "buzz". If it's really that annoying, you can take a length of rubber tubing (no metal) and listen to the buzz coming from the chassis kind of like a stethoscope. STAY AWAY FROM THE HIGH VOLTAGE, please. The yellow picture sounds like a blue chroma failure. A tube can be rejuvinated if need be but that's a job for a pro. Hope this helps.
