Question about LG RU-52SZ51D 52" Rear Projection HDTV-Ready Television

3 Answers

4" along one side of screen has lower intensity

I have had my TV for just over a year and never had any problems with the image on my screen. However, 2 days ago I noticed that the last 4"-5"" of my screen (vertical line on the left side only) have dropped in intensity by about 80-90%. This occured suddenly and there were no noticable indicators prior to this. I have ruled out a problem with incomming signal by trying out my DVD with the same results. The TV has not been moved, or bumped, or exposed to any harmful elements (including magnetic fields from speakers). Any suggestions before I contact aervice rep? Thanks in advance.

Same thing has happened to me but the tech said the light engine has gone out and to replace it cost as much as the tv. So after this I will never buy anything with the words LG or projection. Please don't buy this junk get a plasma or lcd.

It is the lamp. I just recieved this exact set which had a bad lamp. I installed another lamp from an older projector that I found and I now get a very dim picture all over and I noticed the black on the left side. I will be ordering a new lamp soon as the one that I put in isn't enough wattage to show a bright picture. But I at least know that the set works.

If Im not mistakin this is a DLP projection system. The problem your describing most likly is not the dlp display chip Your problem sounds like it could be a reflection problem like smoke dirt or dust on the lens or light sheld or light reflector. Im thinking could even be the lamp its self.

Pain in my left groin area, female, where leg meets groin, 24 hours now. Ok when lying down or sitting, hurts terribly when I walk age 53

Ask a relative or trusted friend to help you reach medical clinic or doctor's office.

https://www.healthline.com/health/pain-in-groin-area-female-left-side#seeing-a-doctor


When to see a doctor

See your doctor if:

home treatment doesn’t help resolve your symptoms

the pain gets any worse over time

the pain happens suddenly without any obvious cause

you can’t walk or move your lower body without intense pain

you experience changes in your menstrual cycle or you miss a period

you see any unusual discharge from your vaginna
You should seek emergency medical help if, along with your groin pain, you experience:

blood in your urinne

pain spreading to your chest, abdomen, or lower back
a fever

nausea or vomiting

Your doctor may use one or more of the following tests to help diagnose the cause:

physical examination, including feeling around the area
X-rays to see transparent images of tissue in the groin
ultrasounds to see real-time images of groin tissues

magnetic resonance imaging (MRI) to see 3-D images of the groin area

The bottom line

Left-sided groin pain isn’t always something to worry about. Mild injuries or minor infections can be treated quickly and easily.

But sudden, intense, or chronic pain may indicate an underlying cause that needs medical treatment. See your doctor as soon as possible if your groin pain disrupts your daily life or can’t be treated at home.

Sony rear projection tv kp-51ws500 no picture. Standby light blinking red 5 times. TV has sound but no picture. Before the picture went out TV was turning green then red and had curved lines going...

Blinking 5 times is a sign of at least one of the three video tubes overcurrenting, which will eventually shut off the image. It happened with me but with my red tube over-illuminating. The solution is to reduce the drive intensity on the offending tube. Remove the front speaker grill. Behind it you will find a panal with 6 pots, these are drive (brightness) and focus for each of the 3 colors. My fix was to turn down the red intensity to zero and (after a restart) bring it up slightly till the image was acceptable, colorwise. I did have to adjust all 3 intensities to get a decient color balance along with the focus's on all three tubes (the drive intensity adjustments will knock the focus out as you go). I used the auto-adjust patterns to focus on, and you may want to use a stationary image, such as a paused DVD scene or a video game, to focus on. I still haven't found a way to clear the error code, but I learned to ignore it. The result isn't perfect, but it's very acceptable and it'll do for awhile (and it didn't cost anything!). Good Luck.

Sounds like the guns may be going out. See if you have a calibration feature on your main menu to calibrate the screen image, and try that. If not, it's possible that your projection guns are going bad. Mine behaved similarly to this (JVC i'Art TV) and that was the repair.

Red-striped ghost images.
