Question about Hitachi 43F300 43" Rear Projection Television
I have a Hitachi 43F300 that worked great for a few years but suddenly the illignment is off so everything is purple with a green shadow... how do i fix this? I'm great with electronics and I've been told that if i take out the green bulb and shake the hell out of it that would probably fix it. is this true?
Gee I'm pretty good with electronics and I've never heard that joke!
What you have there is a convergence problem. Your unit takes two STK392-110 Ic's at position numbers IK04 and IK05 respectively. Also check and replace as necessary Rk50 (2.7ohm /1w), Rk62 (2.2ohm /1w), Rk63 (150ohm /2w), Rk46 (1.8ohm /1w), Rk42 (3.3ohm /1w) And Rk43 (220 ohm 2w). In fact test all of the 2.2ohm resistors in the yoke return just out in front of the amps for change in value.
Also make sure to use Sanyo original Ics and not some asian knock-offs which are readily out there.. Get them from Acme in Florida http://www.acme-sales.net/index.shtml and rest assured you're getting Sanyo originals..
