Question about Hitachi 53FDX20B 53" Rear Projection Television

3 Answers

Hitachi 53SDX01B, audio but no picture

Picture kept getting darker & darker. Took back off tv and blew dust out of tv then had no picture, completely dark. locate 7 leds (5 green and 2 red, all brightly lit except on circuit board on right side where 4 green & one red leds are located. The green led closest to rear of tv is dimly lit compared to all other leds. Fuse where power cord comes into tv is alright. Where do I go from here I have no matenance manual.My 8 year old Hitachi CRT 53" was a little weak for the last few years (dirty?), but then over the course of 4 or 5 days suddenly got progressively weaker until picture gone completely. Unplugging for a day and and repowering does no good. Will take cover off and look myself but I am reluctanct to spend $153 on diagnosis since it's so old. Any ideas?

There is a light bulb (Lamp) you will have to replace it is standard. For rear projection they are quite expensive. Although cheaper than the tv.

Did you check the bulb ?

Check to see if the horizontal output transistor is shorted or not .

I need to replace the dust cover on my Hitachi 53SDX01B


the problem here is Hitachi usually if it still has it sells all three screens as a unit---expensive.

You may want to search with GOOGLE the internet as some companies sell replacement "protective" screen replacements.

I have even seen one time someone found a piece of plexi-glass and had it cut to the exact size and thickness for a replacement.

How to fix my hitachi 65 tv


If you are saying that the picture is getting darker and you have already tried to adjust the picture through the menu feature on your TV then it is more than likely the cooling fluid around the CRT tubes. Over time the fluid in these tubes gets cloudy and causes your TVs picture to become dull and distorts the color. You can google tv repair kits .com and I believe they will have a kit for your model.

Clean the lenes inside of the TV and the mirror and screen (a little dust build up on these three things adds up quick!) also if you smoke that can build up too! these tvs have too be cleaned inside

Hitachi 53SDX01B Rear Projection Television - No Picture


i have a 50" r.p. Hitachi, kinda had the same problem, it would go off at different times and i't hit on the back and get it to come back on,but after awlhile i'd have to hit it more and harder to get it back on till it quit, the menu would come on and would show the video 1 ,3 and that in the corner.After paying $75 for a guy to say it wasn't worth fixing i tried myself. Not knowing what i was doing, i checked all wire plug connections. Found 2 that wasn't seated good replugged them and still didn't work then tried the bulbs, just kinda jiggled all 3 one didn't feel the same so just tapped on it alittle and it popped, i guess back into place, anyway turned on the tv and it worked. Had moved it recentlly so i don't know if that is what moved the bulb. Hope this helps, also mine is a '94 model.

No sound on hitachi 53sdx01b


The first thing to try is rescanning the Freeview channels as it may just be a software corruption...if you have the option of "1st time installation" pick that.Also let me know if there is any buzzing sound coming from the tv..
