Question about Hitachi Televison & Video

1 Answer

I have an old Hitachi 55FX20B rear projection and recently started acting up with a similar old post I found on this very informative web site. Thank you Sal58

I see lots of black horizontal lines across the screen, the lines are really bad when I first turn on the tv and over a few minutes they decrease but not totally gone, I read that it could be some filter capacitors that have aged I'm just not sure which one/s , I can't seem to get a schematic for this TV, any help would be appreciated.

SOURCE: Red lines on Sony KP51HW40 Rear projection TV

This should be a very simple fix. The lines on your screen are call retrace lines. Basically you need to open the TV and the job is about 15 minutes to solve the issue with arched lines, either blue, greed, or red. There is a great how-to guide here: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

SOURCE: Horizontal (dashed) line across screen

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Where can i get a replacement projection mirror and screen for a hitachi 53FDX20B


They are available only from Hitachi.



If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.

My hitachi 55fx20b has a shift in color. red, blue and green does not project at the same spot. what can be the problem?


It sounds like what is called a "convergence" problem; 3d looking with colors out of place etc.

Most of these sets use two of the STK-392-150 chips for this (see photo) and you can look inside to see which are in your set.

A pair of the chips on EBAY sells for about 13 dollars and the only other parts usually involved may be a resistor damaged when the chips failed----this is the exception rather than the norm.

If you or someone you know can solder, etc I can tell you the best way to get at the parts and everything you will need to do the repair; for me----I have repaired over 1,000 sets with this kind of problem.

I am attaching photo of typical convergence problem and what one of the STK chips looks like (chip is 2 1/2 wide/ 1 1/2 tall with 18 pins).

If the photos and this information told you something you did not know rate this solution as very helpful as I do this here for free.

My hitachi tv keep turning off after 5 minuted of


I just got done putting my panasonic 50 projection back together. There is a thermal cut off relay on top of your bulb box, can normally be seen after removing the back of the tv. With the tv unplugged make sure the area around this relay is clean of dust. If the simple fix dosn't work make sure your cooling fan is coming on with the tv.

I have red burn/sun spot growing larger on my hitachi 50v500 what is the problem


I have the same problem and just got off the phone with Hitachi. explained my problem and that I had read similar posts for this web site. Hitachi rep was very courteous and said that after I had set evaluated by any authorized repair shop, they will ship part needed for repair. He even gave me the name of an authorized shop in my area which I call to set up an appointment($40 charge). Called and made service appointment and person I spoke to said based on my explanation problem is probably light engine and if so labor cost to replace would be around $300 but he added part was very expensive so I guess I can't complain since set is out of warranty. Hitachi # is 800-654-7013. Suggest you have model and serial # handy when you call. Recent lawsuit filed against them may be the reason I encountered no resistance by Hitachi. Thanks to all who posted suggesting this tactic.
