Our tv has developed a yellowish vertical oval in the center of the screen. I saw another post that shows it's probably the optics engine. Is this the same issue?

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.

Optical block failure. There was an inherent problem with the optical blocks for this TV and Sony has yet to issue an extended warranty for this model. The only way to fix it is to replace the whole optical block. This is very costly ($1000+) and time consuming (need to take whole TV apart).

There is a pending class action lawsuit for this exact problem. Link to the lawsuit website: http://www.sonya20tvclassaction.com/main/home.sfx

This is caused by a failure of the optical block of your TV. The only way to fix the issue is to replace the whole optical block which is very expensive ($1000+) and time consuming (need to take whole TV apart to replace the part).

The optical block in your model had inherent issues and there is currently a class action lawsuit pending against Sony for this issue. Up to date information reguarding the lawsuit can be found here: http://www.sonya20tvclassaction.com/main/home.sfx

Yellow hue circle in middle of screen. after leaving tv on all night


spherical or oval shaped light starting in the center of your picture is an indication of an led backlit tv.. probably a hitachi. solution, replace light engine..ps no garuntees not with led backlit sets.. was bad idea to begin with. when the leds start going they start at the center and branch out.

I found out it was a bad light engine. The repair cost is $1,700. I'm glad it's still under warranty.

Vertical line down the center of screen


A WD62827 is a V30+ chassis and is a DLP format projection screen Tv, not a flat screen, am I missing something?? For the symptoms you're describing with a WD62827 remove and reseat the DVI cable between the chassis and optical engine. If removing and reseating the DVI cable does not resolve the issue you may need to replace the Optical Engine part # 938P019020
BTW the current software version for this unit is 7.04.1F if you have anything less you might think about updating the software also..
Hope this helps!

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?


No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.

A line on the screen


Is the line perfectly strait? Is it seem to be yellowish in color? If it seems yellowish then the light engine is the problem is the blue panel is defective. Sony covers the light engine for two years. The labor you will probably pay for but, not bad concidering the part is 1000.00 or more.
