Make sure you have the PS3 set to the correct frequency for the TV. Many cannot accept 1080p / 24fps etc.

Try different settings.

I hope this helps.

You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.

When we turn our TV on we get sound, but our picture is distorted for about 15 min then it's clear. Any sug?


Your TV is about 5 years old.
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.

Laptop screen suddenly starts flickering with warious color bars


Hi,

If your lcd screen got harizotal line ( Pink, blue or red ) and flickering, that means your lcd ribbon or board on back top was crack or faulty I believe your lcd screen model is LG Display. There are not have any way to repair it. You must be replace with another lcd but I suggest you to change it with Samsung brand lcd screen. You can buy new lcd screen from ebay.com

Hi i have a 42" LG lcd tv .When i switch it on


the inverter for the backlight likely has a bad capacitor or more. The fluctuating high voltage is causing the jumping and eventual blackness until sufficient charge is on the caps, at which point it stabilizes...it eventually will stay black unless the caps are replaced.

Flickering screen


Two models of the 46 inch Sony Bravia have a screen flicker problem. On my 2008 model, starting from cold, it lasts for 5-10 min, on LHS of screen. The Telefix tech who visited said this is common with these models (46in only), a new panel is needed. Sony provides warranty on this fault for 3 yrs, so you do not need extended warranty to claim. Discuss your case with Sony or Telefix.

LG L1900E flickering after cold start


This is probably due to a bad solder joint somewhere. Bad solder joints can effect a unit in the reverse also. IE works at first and then dies after it gets warm. Think about how metal expands when it is heated. And contracts as it gets cold. If there is a hairline fracture on one or more component joints, this would cause it to not have such a great or solid connection when it is cool, or contracted. As it gets warmer, the solder expands therefore filling the void and giving it a good connection.

Regardless, it will likely only get worse over time. If you're handy with a soldering iron, pop it open and reflow all the joints. Especially the ones on the transformers and copper coils. Best to hit them all, excluding the tiny surface mount devices.

If you need further help or if you'd like to have this, or any other LCD monitor repaired for a flat rate fee of $40, please visit my web site http://BoiseLCD.webs.com, or email me at cjmclellen@msn.com.

Flickering monitor


this problem many caused by bad inverter. If invertes not function, it won't feed back a good signal to tell mainboard that LCD backlight is working, so the mainboard turn off the display.

To fix this problem, it is need a qualify technician and inverter's part.
Send it to LG, they will not charge you expensive. LG have a great service.

May this help.
