Color issues with Hitachi 60V715

I have a Hitachi 60V715 that I've owned for just over four years and am still on the original lamp. The set is used for several hours a day practically every day.

Recently I started noticing what appears to be a yellow tint to flesh tones and blues are portrayed as more of a blue green rather than solid blue. However, color appears normal toward the edges of the screen.

As stated, I'm using the original lamp, but brightness seems to be OK, although not as bright as when it was new.

Can an old lamp cause color issues or do you think I have a more serious problem? And if more serious, would it be possible to provide an estimate of what it might cost for a fix. Bottom line, would it be worth while fixing this set or should I look at buying a new one if the fix it too expensive?

Thanks so much.

You likely have a problem with your Optical Engine. It is very expensive to replace and should fix the problem. The lamp cannot cause color issues. You may have dust/dirt contamination in the engine and it could be clean by a servicer or technical person. The blue LCD panel or polarizer may have failed in the engine giving you blue and yellow (lack of blue) type symptoms.

Iput in new lamp 25 days ago as working good. now when i t/on tv. It comes on for about 20 sec @ then t/off for aout 20 sec. By it self. and keeps repeating on/off/on/off/on/off picture @ sound ok.


The lamp of course would be logical to suspect---the only suggestion I have as have seen this before is some of these sets if enough dust inside will do this---seen ones that would play twenty minutes and either shut off or off and on.

Seen dead ones also where dust on the fans slows them just a little-set monitors things like that===usually we take back off and set outside with a air compressor and clean all air channels out (air gets taken in from front area and exits rear).

It at worst will rule this possible solution out and at best may resolve the issue. Seen say fifty or more sets where after cleaning with air (no matter how clean the house is it may look like a dust storm when you air it out) the issue was gone.

One even had golf ball sized white spots in picture--dust inside the two month old set's light engine.

Good luck and I hope it helps as it cannot hurt.

Installed new lamp on my hitachi60v715 no picture or sound


Possible power supply or Lamp Ballast that has instantly blown a fuse.

If no power or lights etc someone has to open and test voltages etc.

If beyond you---have set taken to a shop---a house call is usually a waste of time and money in this situation.

My problem started with a yellowish blotch in the middle of the screen. Now the color keeps chaning so that everything is shades of green. Where can I get an Hitachi optical block myself?


the light engine is most likely the problem or it has dust ball up in it.
check the lamp for discoloration if all looks OK . that could get costly.
if you have never worked on this set you can destroy the set be careful or take it to a shop.

Picture is blurry/distorted. I see here on the website the possible solution of replacing the 60V715 TV Lamps. Any advice?


Confirm the actual model number of the set you have.


53SDX10B IS A REAR PROJECTION WITH TUBES AND THE OTHER MODEL IS A DLP WITH NO TUBES.

Have a green tint over 90% ot the center of the screen


I had the same problem with my 60V500A about a year ago. The screen got a red tint in the center and the image was fuzzy in that area. A new lamp didn't solve the problem. I did some checking and found out that the original light engine used in this model had a cooling issue that could cause the light engine to overheat and distort the LCD panels. My warranty had run out more than a year before this happened so I figured I was screwed since the light engine was so expensive. I decided to call Hitachi tech support and see if I could get a discount on the cost of a new light engine since the cooling problem was a known issue for this model TV. I calmly explained to them that I was aware of the cooling issue in the light engine and that I felt like a $4000 TV should last more than two or three years. Tech support gave me the phone number for my local authorized Hitachi service center and I gave them a call. Once the technician confirmed that it was the light engine that was the problem Hitachi sent him a replacement light engine at no cost to me. I was WAY past my warranty period so I still had to pay for the labor to replace the light engine. $300 for labor was a lot cheaper than buying a new light engine or tossing the TV and buying a new one. I have to say that Hitachi earned my respect for admitting there was a problem and doing what was needed to correct the problem more than a year after my warranty had expired.

I would first check and see if any software updates are out on this set, you can call Hitachi, if not that then it could be the engine assemble having problems.
