Question about Hitachi 51F510 51" Rear Projection HDTV-Ready Television

2 Answers

Good Evening, We have a hitachi large screen tv. It isn't a new one, approximately a 1998 model. We had been experiencing the problem of it shutting down. When we would turn it back on, everything would be alright until the next time it decided to shut down. I had gotten on a website where the information was given to me that it sounded like a resistor #51 needed to be replaced. Could this be correct? Please let us know.

The 51F510 has been out since around 2005, like tech 1819 said there are issues with cold solder joints on these, also touch up the connections on the large heatsink grounds (I run jumper wires), the vertical IC, and various other large connections that may have small ring cracks around component legs.

Most likely you have cold solder joints on t401 the horizontal drive tranformer. Also check that little blue capacitor in front of the horizontal output transistor.

Hello I have a rear projection Hitachi TV from 2000/2001 approximately 48 inches. I am getting a red shadow cast all over the screen, I have tried the convergence button but it is not helping.


Hi, thank you for visit fixya.
STK IC's need be replace, and possibles resistors burn too.
We call convergence problems.
For best results, take your tv to near tv service and request help for convergence parts, or you can find at encompassparts.com , just provide model number tv and they will help you.
Any question, let me know please.
Thank you

Hitachi model 60v500a.the middle of the screen is a little yello


If you Google "60v500a light engine" you will learn a few things about this set which was first sold in 2003.

There are some class action lawsuits out there for several Hitachi models made at about the same time.

Most of the time these sets develop a discolored area fairly large in the middle of the screen---a lot of them had a large red or pink oval area but other colors are possible.

This set uses a LAMP for the light source and it directs the light into the optical light engine--at the top of the engine is a 3 inch lens that the picture comes out of and is directed into the mirror which puts it on the screen.

Lots of these sets develop a "burn" inside the engine from the heat--there are a series of lens and baffles inside---even slight separation inside will change the color in some area of the picture.

I am sorry to give you bad news but I have replaced a lot of these engines under extended and when they were new mfg. warranty.

The part is no longer available from Hitachi new--the only way to get one is to remove the one in the set and have it sent out for "rebuild" and the last time I saw one the engine was over 600 dollars at the wholesale level not counting the fact that it is major labor to replace.

Find someone in your area familiar with Hitachi and this model and you will see what I am talking about.

Even though this is not good news, I think it is what your problem is.

My hitachi 57f500 turns itself off after 3 hours of use. Turning it back on restores the picture,


Hi I am Vortash
There may be actually nothing wrong with your set ? .......
This set has an anti surge protection circuit and it is designed to shut down should the incoming power peak above 240 volts or more , is this happenig at random times or around the same time in the evening or day it may be that this safety device is protecting the set .. sometimes local area transformers peak at the time of most consumer requirements this may just coincide to when you sit down to watch tv .. however if it has a habit of doing it at different times during the day .. then this safety circuit may be at fault and require an engineer to service the tv and check for poor components that have changed value .. It explains this is in the manual if you do not have one for your set you can download one for free from http://www.safemanuals.com hope this is of help regards Vortash

Too large of screen on hitachi rear projection tv


Some models had a 'zoom' feature on the remote, don't know why only some channels would show and others not. Try unplugging it overnight, maybe it will reset.

Hitachi 50SBX78B 50" Rear Projection TV


If the power supply board is the only thing affected, I would suggest calling PTS:1-800-844-7871 and give them the model and what you are looking for. This would be the simpliest thing to do. They rebuild boards and maybe more cost affective than trying to repair yourself. Hope this helps!

Scrolling lines in the picture


The capacitors in the sweep supply and maybe in the main power supply are starting to dry up. Your going to need to get a tech to go over the boards and search out the dryed capacitors. It will take some time and maybe a bit costly. May want to think maybe about a new set? Good Luck
