Hitachi Ultravision 46UX50B Flickering/Dead Display

I have an older Hitachi Ultravision 46UX50B that no longer displays an image with any consistency. The picture will sort of do a quick flicker, then go out. No backlighting, just a dead screen. When you stomp the floor, it comes back on, but not all the time. Do I have some bad solders? Loose wires? Help please.

It is possible that you have some loose connections, but I have seen the relays in the power supply get to be intermitent and will not stay closed. Tapping lightly on the relays will usually tell whether or not they are bad.

How can i fix my hitachi ultravision it has green and double vision on top of screen


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Upper sise of screen flickering problem


Technology b> A laptop's display assembly consists of an LCD panel, an inverter board and a backlight lamp. The inverter board supplies power to the lamp which lights up the LCD screen as it generates images. Light from the lamp is then uniformly distributed over the panel to create images. b> Cause b> Flickering is commonly caused by a damaged or malfunctioning inverter. Because a faulty inverter is not able to supply adequate power to the backlight lamp, the screen goes dim each time the backlight loses power. In some cases, flickering may also be caused by a faulty connection between the inverter and backlight lamp. Diagnosis b> Resolving a laptop screen's flickering problem entails correctly diagnosing the problem and replacing the faulty component. You may diagnose the problem by hooking up the laptop to an external display unit, such as a projector. If the external display has the same display problem as the laptop's LCD screen, it is indicative of a motherboard or video card problem. If the external unit displays bright, crisp images, the problem is probably caused by the backlight or inverter. b> Solution b> You may repair a laptop screen's flickering problem by replacing the inverter board or backlight. Order parts from a trusted supplier and replace the component by referring to your product documentation.

I'm not getting any red in my picture on my hitachi rear projection ultravision tv


A model number would help here but if it is older and uses 3 picture tubes carefully with the back off and set on does the red one come up and produce a red image?

Many thin black horizontal lines on my Hitachi Ultravision 50" TV


Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

I would like to order an owners manual and remote


Hello,
I have found a couple of sites where you can download the owners manual for a fee of $9.99 but I have been unable to find a site where it is free. Hitachi web site does have several owner manuals but do not have the one for this tv. My owners manual is a photo copy of the original manual. I got mine by calling Hitachi (1-800-448-2244) shortly after purchasing the TV, it was a display model and did not come with one. I have just bought my second remote, first one when I got the owners manual and second one just a couple of weeks ago through sears parts. Once I get a scanner hooked up I will try to upload my manual to this site.

If you would like the service manual, go to http://www.schematicsforfree.com/archive/?path=Video%2FProducts and scroll down to 01-21-08 29842400 pdf.gif Hitachi 46Ux50B.pdf
this is the "service" manual for Hitachi models 46UX50B/51K, 50UX52B/53K, 60UX54B/55K, 50SBX70B, 60SBX72B, 70SBX74B. These are the same model numbers listed on the owners manual.

I hope this helps someone out. Shera
