20 Most Recent Hitachi 50V500 50 in. HD-Ready LCD Television - Page 3 Questions & Answers

I ran into Bee Hive of problems and don't know where to start. I have read problems that are related to the convergence , one definitely a fan motor. A couple sounded like the color IC on the CRT board. Some sound like bad caps in the power section. Some sounded like a picture tube alignment problem. The one that wouldn't turn off sounds like a relay stuck or burned closed. As I read down I noticed some problems that would have to be done in a well equipped shop.. I really don't know where to start. If someone will give me a specific problem I will try to solve it. Reading down I got confused, is this all one TV? Col. Dana Gillespie

Toy should start troubleshooting from it main power supply [SMPS] board itself. It will be best to contact any service technician, or authorized service center for Mitsubishi. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/

main board fault. Shorted component/s at it. Contact any service technician. Gopakumar Gopalan Google

LOL sounds like you just need a new TV buddy, there are multiple components that are going out, first start with the green lines or "pixelations" these are caused by the tv no longer being able to regulate the electricity in those pixles and are as a result 'Open'. The 10 minute things is more of a energy conversion thing and sound and video on and off are connection issues (internally) so take it to a repair shop but if the price to fix is greater than 1,000 you should be willing to scrap it for a replacement. who knows the shop might buy it off you for cheap...

Good Luck

This is my Fav...
pricey though but can keep an eye on ebay for half price divorces.. :D

To get more details about this, check the site linked here. It is difficult to type in and enter tables here by this window. http://electronicshelponline.blogspot.com/ Pull up older post. One among it have details about convergence adjustments.

Did this happen before or after you tried adjusting the colour?

Check the door switch, there is a switch that has to be seated properly on the door where you opened to replace the bulb . Sometimes these things can be a real pain. The set will not at all if this little switch is not seated properly. Just what I would look at first hope it helps. Gillight

There should be any short circuited component/s at its horizontal scan output section circuit. In most cases, the horizontal scan output transistor is found faulty. Replace it, and check. If you wish to get some details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Timeslide / Flipcard, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

While you have sound, take a flashlight and shine it on the screen, look very close and see if you can see a dark video image.
Let me know what you see.

its posbily a fuse inside

First, if your Hitachi is more four years old, it'll start having colour problems.

Projection TV correct? This may take some work but it is common for a spec of dust to settle onto the Mirror inside the TV, The back side of the TV screen or onto the Lens from which the Video image is projected. Some TVs have ports that allow you to access the inside of the TV from the side, others you must remove the screen.

This is not something to do every day or every week and it will not improve the picture. You only do this when you notice that it is dirty. Any more than that and you yourself will create a bigger problem. ONLY LIGHTLY DUST the screen. Soaps, water and windex will leave streaks, damage the screen and cause more trouble.

Projection TVs are the eqivalent of a big flashlight showing onto a wall. Put you hand in front of the light and you get a shadow.

Inside you TV there is a light (the TV picture) that bonces of a mirror attached to the inside of the back of the TV. The light reflects off the mirror onto the back of the screen. You view this refelected image from the front. Spiders commonly make webs inside the TV that appear in the picture. Dust Bunnies may get blown into an area and become stuck in the way. Sometimes a lite tap, shake or blow may remove this also.

Have an extended warranty like me, well even though i did purchase one I still am pissed. I paid $3300 for this set 60v500a and like I suspect many the red cloud just crept up on them until it became a real nusiance. I called Hitachi first but they were unwilling to help at all and tried to tell me it was the bulb, thank god for the internet or I might of believed them (-$400 out of pocket because warranty doesn't cover bulbs). Went to the lawfirms website and sent an email to add me to the many names in the lawsuit hopefully will hear back from them. Was pissed to find out that the repair shop is going to replace the light engine with a refurbished part. Didn't buy a refurbished TV but get a refurbished part well will be keeping a close eye on any red clouds in the future considering I still have a year and a half left on the warranty and will be complaining of any problems. For all others I will be asking the repair man if this is a common problem to share with others. I hope the lawyers hold Hitachi responsible for this, got a lotta nerve selling defective junk to consumers but corporate greed knows no bounds i guess.

It will be more better to buy a new TV, than trying this TV repaired. The screen itself will cost around 2/3rd of the total cost of the new TV. Just think about the total expendature that you will have, including repair charge.
