Question about Hitachi 60SX13B 60" Rear Projection Television

1 Answer

Darkening screen (or of programs?)

Hitachi 60SX3B V4HAug 94 My wife and I have noticed, over the past couple of months, that many received programs have become much darker than before....for instance, in low light situations (as with the characters being in rooms as opposed to outdoors) any character or item in shadowed areas are almost totally blacked out. Does it corelate to a differing signal now be broadcast for HD? Really puzzling and irritating as some shows are almost non-viewable at times. Wondering if there is a way to brighten the projection. there is no halowing, converging problems, etc. When not too dark the picture is crisp and enjoyable. Dennis

Re: Darkening screen (or of programs?)

Use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Hitachi rear projection model 57f59a makes loud popping sound from time to time

Yes and it is common---the set uses 3 picture tubes and where the high voltage (well over 10,000 volts) goes into the side of each tube via a spark plug type wire (with good reason) they completely seal the rubber clip that inserts the wire into the side of the tube.

You are describing almost perfectly when one of the tubes arcs around the anode (what the opening is called--2nd Anode to be precise)

Two things are going to happen--when it pops it can instantly burn the coating off of the offending tube's screen resulting in a burn mark--usually dead center and if red tube arcs the mark will be yellow(only red and visable in that area of the screen.

This damage is permanent once it happens-----Second is that it will arc hard enough to blow some other part out in the set.

let me know if questions.

The color is going. Could it be the lamp?

if it is darkening then yes. if it is giving you colors on the screen like a blob or star pattern it is the optical block.

It looks like the red is not converging on my Hitachi 60V500A LCD Rear Projection Television. I'm thinking that I need a new Lamp Engine. Does that seem correct?

Good Luck with this. We have complained about a darkening screen we were told to replace the lamp. We did so for $100. After the problem was only getting worse, they said it was because I did not purchase a "Hitachi" bulb. They stated they knew their's were more expensive ($300) but should solve the problem. Well, we didn't bite. It became clear that we no longer could see blues, pinks, yellow, and most browns. A call back to customer service stating these problems ended with us learning we needed to replace a color engine to the tune of $850-$1200. We have only had the tv for about 4 years. Needless to say we bought a new Samsung Plasma for a little more than the replacement part. Hitachi products, never again.

Screen getting dark

If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it

Bluish hazy texture on my screen

It sound like the light engine is going out or already out. I would take it to a certified Hitachi dealer have them check it out then I would call Hitachi to have them fix it for free.

Hitachi tv magic focus does not work

Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

Broken screen

The Hitachi part number for the screen assembly for the 60DX10B is KR01223 and can be ordered from a Hitachi distributor if is still available, but I warn you it is not cheap!
