20 Most Recent Hitachi 50V500 50 in. HD-Ready LCD Television - Page 6 Questions & Answers

Hi,

This issue is related to a power problem in as much as the TV turns off on it's own.

The problem is consistent with overheating on the power supply board of the TV. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby making it to misbehave.

The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.

When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.

To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply board

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board from www/shopjimmy.com to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't have the ability to read the fault, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

Hi,
Both Tvs have the same lamp. You can use the lamp with the following number for both.
UX21511/LC37.
ok

We took in a 60v500a with the same problem, Customer bought a new set. We took hers apart. Here is what we found.
1 there is a squril cage blower and a small air duct that cools the lcd screens and polarizer lenses. Yes there are 3 polarizer lenses one in front of each LCD screen.

These start to overheat and discolor. Maybe the filter for the fan clogs up.

Don't really know.

You can pull the LE and vaccum the filter clean every 3-6 month.

You can remove the lenses and maybe the tv will look ok maybe not. I have read where some have had there repaired and now they see vertical lines in the screen. This seems to be a quike fix by removing the melted lens. Cool A.

I would check your lamp and replace if needed. If that does not fix, I would check the ballast.

The TV has a bad light engine, it's very common for this TV and very expensive. Call the manufacture and try to get a concession for the part. They normally give it about 75% of the time.
Good Luck

I have a Hitachi 50V710 with a yellow-greenish spot in the center of the screen. It appeared there about a year ago. I have been putting off getting it repaired because money has been pretty tight. And they told me that my warranty has expired. They also said that it would cost over a thousand dollars to fix the problem. I purchased the 50" TV 09/09/04 for a total of $3336.88 what a rip-off. Now the whole screen has a green tint and the yellow-greenish circle in the center looks brighter. I wonder if it is even worth getting it fixed? What will go wrong with it next? Its a Lemon.
I really regret not buying the 52" sharp that was setting next the piece of **** that got suckered into buying. I know I learned one thing out of this,
" I WILL NEVER BUY HITACHI BRAND PRODUCTS AGAIN! "

Had that blue spot problem but it never grew. The light engine had to be replaced to fix the problem.

The first and easiest thing to check is your lamp. lamps on these TV's go bad and they are easy to replace.

Hi that could be a couple of things. Most likelly it's your light engine that is bad. or your signal board might be bad. you can find parts for this TV ant www.interliquidparts.com

You will want to keep your aspect ratio on 16x9. On your DISH Network remote press the format button on your remote it will have an asterisk (*) on it. Also, try the page up and page down buttons right of the volume. If that fails take the factory remote and try the format button there as well.

the cooling fan could be going out

You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck

Your light engine is going out. You need to replace the engine or have it rebuilt. Would be more cost effective to purchase a new set.
