Question about Hitachi 51F500 51" Rear Projection HDTV-Ready Television

Leaky CRT's I own a Hitachi 51F500 rear projection TV that I bought in 2003. Two weeks a go I noticed that the TV was shuting down by itself. I took off the back and noticed some standing liquid (antifreeze) on the circuit board. One of my CRT's leaked. I understand this is a common problem with Hitachi. My question is, "...is the repair which will cost around $300 worth it?" The tech can't garauntee other issues won't come up due to the leaky CRT in the future and I could buy a new TV for $500 - $700. --thanks

I would not repair unless you also replace any circxuit boards that the liquid fell on. although it is now water it will corrode the parts & will most likely cause further problems. the only way to ensure that future problems are not related to this is to replace the boards affected. good luck.

It pops for awhile, then stops for about a week then it will go out completely. Place the tv in a corner for about a week turned off and then turn it back on, it will work again for awhile.

This could be caused by the high voltage transformer arcing or one of the anode leads arcing at the CRT cap. If you can monitor the back of the set open while in a dark room setting may show where the arcing is occuring
I hope this helps,

Thats usually a isgn of a weak resistor on the red crt PC board or the red CRT getting weak. You can also try turning the RED screen control down slightly to see if that helps.

Hitachi 51f500

It sounds a lot like a micro/eprom problem and Hitachi addressed this in a service bulletin quite some time ago. Their fix was to add a jumper from I007 pin 1 to cathode of D019... Problems ranged from picture freezing to on/off control without prompting. Not an expensive fix and can easily be done in-home if you get a good reputable shop. We've done several in-home on a simple service call.
Hope this helps!

Hitachi 51F500 (Two separate problems?)

My guess is that the sound you heard was that of some High Voltage discharges that could have fed back and damaged some semiconductors including the microprocessor itself. Since it could be a very expensive repair, I would be very tempted to look around for a new HDTV by JVC or Toshiba. Hitachi has slipped a notch or two in recent years according to my experience.

TV Flickers up and down and screen is shifted to the right w/ red color dominating the screen.

the last hitachi that had this problem i fixed it bad finding bad solder conenctions throughout the board that the convergance ic's are on, also i foind some on the two main board in my repair. hopefully resoldering the convergance foard will fix the jitter or jumping around problem. if the picture is too red you can also try turning down the screen control slightly. good luck
