20 Most Recent Hitachi 46F500 46" Rear Projection HDTV-Ready Television Questions & Answers


Hello... Rear Projection TVs are not easy to work on. That being said, color issues can be caused by several different things. The most common involves the CRTs (there are three small picture tubes). There is a fluid in each tube that over time can dis-color, and involves a very difficult procedure to fix. Next, there are convergence circuits for each CRT, and one or more can fail. This will not usually cause the symptom you are describing, it will usually cause a double image in some or all areas of the screen and some areas the colors will look fine while other areas will not. It could also be a bad CRT drive board, or the video processing IC. It could even be the high voltage splitter! If I were you, I'd consider a new TV (please get the extended warranty). I hope this helps...

Are you using the original remote control...Reg TV doesn't fit your screen because it's not filmed in HD...But it should be clear but you have to watch it smaller... Usually big screen tv's will have a black trim around the picture...And zoom cuts off some of the picture..Some tv's have wide, cinema and other options...Your TV might just have zoom

Connect HDMI output of laptop to input of tv. If no HDMI output look for laptop video output and get a converter for it to go to the input of tv.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

Go to Wal-Mart, Target, K-Mart, Sears, Best Buy, or any store like that make sure you have your make and model written down with you and go get a universal remote they can run anywhere from $15 to $100. Just make sure the model of remote you buy works with your television set. The instructions are usually pretty easy and involve punching in a code - I recommend once you figure out the code you highlight it in the instructions and write it down on a small piece of paper and use scotch tape to secure it to the inside of the battery cover so you have it when you change the batteries.

thats a convergence issue you can get the convergence repair kit which contains the parts and instructions from the www.tvrepairworld.com just click on the Hitachi Repair kits catagory then scroll down the page to your models convergence kit.

First unplug the unit until problem is found---I would look inside for burnt parts like resistors in the convergence circuit which is the most common issue this set has.

They may be discolored or brown in the middle and not actually charred.

Locate what burned and you will locate the area where the problem is, many resistors in that area are protection, if a short they destroy themselves very quickly ....

If you were having any issue before or at the point it started smoking where picture looked odd or even 3d it will be in the convergence circuit.

Not exact but something like this--the two black chips and resistors in front of them.

Check the resistor in front and back of Convergence ICs. STK392-110s. the ICs might need to be replaced also. Look for poor solder connections also.

Please confirm tv model as question shows its Hitachi 46F500 rear projection tv.
How old is this tv?

Hitachi 46F500... | Answered on Sep 20, 2011


If model number is as listed (46f500) it does not use a lamp or bulb but has three picture tubes.

3d means the two convergence chips in the set have failed.

It depends on if you can solder etc, not a very expensive parts cost (under 30 dollars)

Can you solder?

I have a suggestion: when it goes pink go to a black and white channel and examine the screen: if reddish you may be able to adjust the red screen control to correct this.

I can tell you how to do that and please let me know what you find before you rate this information.
