Re: hitatchi tv

Most likely your "light engine" needs complete replacement and it is quite an installation...If not under warranty, usually Hitachi will NOT charge you for the light engine assembly (about as big as a bread box) for this particular V500 series because of all the failures they are aware of..However Hitachi will require a technician to do the installation and first verify that the light engine needs replacement...Hitachi will NOT pay for labor unless the tv is still under warranty. Labor varies. I know that for this 3 hour procedure or more, including calibration after replacement as necessary, I charge $400 or more..Above all pick a highly recommended technician.. Sorry for the bad news.. this happens alot to the V500 series. colors vary..sometimes red and sometimes blue ...this problem due to overheating. The replacement should be an improved assembly, sometimes rebuilt, sometimes new and both usually upgraded so this does not happen again. Do not attempt repairs on this yourself as it requires great expertise; and disassembly and reassembly of top portion of TV requires 2 people. And, on top of that, ever so often the lamp for this tv has to be replaced after a certain amount of hours of play (hopefully 2 years depending on hours of use) and just the lamp alone which you CAN replace yourself is $260 give or take more or less money. Always research any NEW TECHNOLOGY TV's thoroughly before you spend mucho bucks so you know what you might be in for. I try to avoid buying cutting edge technology myself as it's not fully tried and true and tested by any means. It cant be avoided if you want to buy the latest and the greatest motherboards for computers and once in a while I get burned like anybody else. But motherboards are usually only a couple hundred bucks, not thousands of dollars!

You most likely have a large magnetic source near the screen like a surround sound sub woofer or other speakers. also go into the tv's settings and have it auto adjust the convergence. should help

I have panasonic model pt53wx54j rear projection tv. When the tv is on accross the bottom in a oval shape starting in one corner and ending is an oval shape yellow in color. Just above that is a blue color...

If you go into the customer menu and select convergence and it is skewed you need to remove the light box and replace both of the STK-392-110 CONVERGENCE IC chips this set uses.

I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET--I can post them here if you think you or someone you know can do the repair.

Most shops get 300 or more for this repair--if you buy the chips on Ebay (I can tell you the seller to look for there) they and any other parts should total under 30 dollars. The fact that the set is still coming on means most likely just the two chips need to be replaced and the set adjusted with the Panasonic remote for this set.

If you have questions or want the instructions rate this solution and let me know and I will post them here---I do this here for FREE.

Yellow hue circle in middle of screen. after leaving tv on all night

spherical or oval shaped light starting in the center of your picture is an indication of an led backlit tv.. probably a hitachi. solution, replace light no garuntees not with led backlit sets.. was bad idea to begin with. when the leds start going they start at the center and branch out.

Fuzzy picture, oval shaped, scrolling up slowly

I would start by checking the large filter capacitors in the power supply. I can't be sure since I'm not seeing the set, but it sounds like you're describing AC ripple. In a 20-year-old set, some of those electrolytics will be drying out. A few replacements may take care of the trouble for you.

I just replaced my Hitachi T.V's lamp after the first one ran out. Now, there seems to be a blueish glow on the lft side of the screen. It is large and very noticible. is this normal because of the new...

I would have a tv service center come out and look
usually if you have blue or red oval shape on the screen it is a indication . The light engine is bad. cost of light engine is 395.00 on up. Put your tv on a blank screen you will see it,

Which part(s) to replace?

If the screen looks OK after extended cooling is provided, you may just have a failed cooling fan.
Turning the blade with the power off will tell you if the bearings have failed or stuck, or just look at it with a flashlight to see if it is turning.
Check this first before you start replacing boards.

Hitatchi ultravision 53" rear projection lcd tv

You have a problem with the optical engine- The only repair would be to change the engine for about $500-$1,000 plus labor. This is a major repair (sometimes caused by dust particles getting on the LCD panels inside the engine, but disassembling the engine to try and clean it is not a reasonable option)
