Question about Hitachi 57S715 57" Rear Projection HDTV

1 Answer

No green on my hitachi 57s715

I heard a popping noise from my tv, and then the screen blinked and the color went bad. I took off the back cover and the middle tube, the green, was not working. I checked the fused I could find and checked connections, but I am not a tv tech. I am an air conditioning tech and have a multi-meter to do electrical troubleshooting. If someone could point me in the direction to figure out how to figure out if the tube is bad, or if inputs to the tube are bad, I would really appreciate it...thanks.

    Thanks for the comment...already fixed. It was a bad board. The one controlling the green tube was bad. Replaced assembly and everything is golden.

We heard a "pop" noise


The pop noise could be a capacitor poping its top up.This is a common problem to most TV sets today. Usually located at the power supply board.Once this parts give up it usually shorts the circuit and blows a fuse.Replacements of these parts mentioned will often remedy the problem.Flashing power indicators indicate a problem.If you have the chance of counting how many the blinks are I could have told you the problems code are and the source of the problem.

Tv went grayscreen, flickering. turned off, then


When you had gray screen and flickering you had only one problem - color wheel. After "putting everything together" you have totally different problem, caused by multiple possibilities like: forgotten connectors, cut/jammed cables/wires, lamp not being inserted properly, lamp door not being set properly, disconnected color wheel, etc. Try to open rear cover and redo what you have done. Remove optical block, check everything visually and slowly put everything back. If still no luck - then only skilled TV repairman may (or may not) help.

I own a Samsung HL-R5067W 50'' DLP. Set is about 3 years old. Recently I heard a loud pop while viewing, picture distorted, but never went blank. I turned set off. When turned on again a loud whining noise...


Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

You have a defective light engine and Hitachi is aware of it. Here's what you need to do...recently went through this. Call Hitachis customer relations department at 800-654-7013 and tell them you have a defective light engine. At first, they will act like they've not heard of this problem but they are all too familiar with it. They will give you the names of some certified dealers in your area. Once the tech comes out and confirms the problem, call Hitachi back at the 800 # I listed and they will call and confirm with the dealer that you have a bad light engine. They will send a brand new light engine to the dealer (Hitachi will cover the cost $1500) and the dealer will call you to come out and install.

Here's the kicker, if you're not still under warranty, Hitachi will cover the expensive part but you will have to pay the install. Our install was $400 but others on this site have paid around $200. If you're still under warranty, Hitachi will cover the part and install.

Please do not let any dealer tell you that you have to pay for this part. Hitachi has not recalled this part but they are replacing it to you for free...you just pay the install. Also, deal only with their customer relations at the 800# I listed.Good Luck:)
