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

2 Answers

Hitachi 51F500 My email bounced back from your "@willapabay.org" addy...so I'm only able to contact you through this method. You can respond to me at joekirklin at gmail (I'm afraid of putting it all together since this is public...I'm sure you know what I mean) Here's what I tried to email you: Thanks for your fast response to my inquiry on Fixya. The manual I need is for a Hitachi 51F500 - you said something about a UWX20B with a supplement...I have no idea. Please just pando whatever you think is the correct one. I'm in desperate need of a block diagram, since I'm not even sure where some of the start-up circuitry lives (is it all on the main PSU board?) I'm no stranger to working on most electronics, but TVs are certainly not my specialty! So far from my research alone - things are pointing to HOT shorted, as you also mentioned. Is that a good place to start? I'm praying that my FBT is still ok - as I imagine they are expensive, no? - joe kirklin

    Bill,

    I included my email in the above message, but it wasn't very obvious. You can decode my above message or just send it to joeykirklin@hotmail.com. I don't care if that one gets spammed.

    Again, THANKS!

    - joe

FBT for that unit is about 60-80 bucks. You can easily check the hot for continuity across Base, Collector and Emitter. If you have continuity between C&E and B&E chances are the HOT will need to be replaced...
I'll need your email to Pando the service manual - Fixya does not allow for large downloads like manuals...

Video reset hitachi 51f500


There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

The mirror on the back of the Hitachi hd 51 in is broken can a regular mirror be a replacement or can you tell me where can i get a replacement for it. Rob


You can contact Hitachi for a local authorized repair facility.  The mirror has to be pretty precise and it definitely has to be in a specific alignment for the picture to be seen optimally.

Hitachi 51F500 power supply?


The fact that you're getting any action from the primary or secondary relays points to an open short in one or more circuits or a short to ground in one of the Hv load circuits and the S/D circuit is simply shutting the set off in protect mode... We see that a lot with PTV's when the convergence is fouled or the HOT or FBT is shorted or something along those lines.
I will Pando the service manual if you drop me a post to my addy specifying exactly what you need. If I remember correctly the manual for this one is actually a UWX20B with a supplemental.

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


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.

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.
