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

1 Answer

Thermal Expansion Bubble burst ... will Hitachi cover repair costs?

I found antifreeze on my main circuit board of my Hitachi 51F500. I thought one of my CRT's leaked but a tech was out today and it turns out that one of my Thermal Expansion Bubbles burst. Hitachi paid for the $99 trip charge for the tech to diagnose my problem. My question is, "... will Hitachi also cover all charges to repair the TV?" The tech said I will have to replace the circuit board also etc. Has anyone worked with Hitachi before? So far, they seem very accomodating. -- thanks.

It is actually an expnasion valve and try contacting Hitachi directly as they usually are pretty good about working with consumers. Although id the TV is out of warranty there is probably nothing they will do but, it doesn't hurt to try.

I am still having the blury wording on my HITACHI 51F500 the three focus buttons seem to do nothing when I turn them

If you turned the focus buttons (controls) you just made matters worse--if 3d etc the convergence circuit needs REPAIR which consists of replacement of the the two chips used.

My Hitachi TV Model #51F500 is showing shadows and double lettering (in other words a terrible picture). Please help.

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Scratch Screen

Sorry about the late posting. The protective screen can be purchased from using the part number KR2074. This will cost $80.36 plus shipping. This should be a straightforward replacement. The instructions are included with the screen.

Hope this helps,

Leaky CRT's

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.
