SOURCE: LG Projection TV has dark picture

Normally the main cause of any DLP having a dark picture is the lamp. I would replace it and it should look like a new set again.

SOURCE: Tv picture quality

You have a defective light engine. We just went through this and we have the same TV that you have. Hitachi knows about the problem but will play dumb when you first call. If you deal directly with their Customer Relations Department 800-654-7013, it will make a lot of difference than regular customer service.

Here's how they handled our situation. We called Hitachi after lots of research online and they gave us the names of some certified dealers in our area. The tech came out and in less than 1 minute said the TV had a defective light engine. We called Hitachi back and low and behold, they are aware of the problem...imagine that. Hitachi called the dealer directly and once the dealer confirmed the problem, they agreed to send a brand new light engine out to the dealer and the tech came out and replaced it. Here's the kicker...Hitachi will pay the for the part ($1500) but they ask you to pay for the install. Our install was $400. This was worth it to us being that we spent $3600 on this set 3 years ago. Once the light engine was replaced, the TV looked BRAND NEW! Please deal with their customer relations department at the number I lised above. If you deal with customer service, they will have you chasing your tail...so to speak! Good Luck! If you're willing to cover the install, the rest should go pretty smoothly..at least it did for us:)

SOURCE: Black/Green Distortion - Picture Quality - Wharfedale

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

Hi, I have an LG RZ-20A70 TV and when i watch TV or play xbox the side are cut off the screen. (think its the picture ratio) any idea how to change this? as i have tried everything!


yes it is a picture ratio issue .
You need to look for the main menu tv setup button, its green on my lg remote .
Once you select this you should have an option to change screen ratio to 16.2 or wide screen if your tv supports wide screen .
Look for a little tv icon on screen and select that ,this should get you to pic set .

Need tv code for sky remote tv is an lg lcd


  • Turn your TV on.

    2. Press tv on your Skyremote control.

    3. Hold down select and the red button together for about two seconds, until the red light on the Skyremote control blinks twice.

    4. Press tv on your Skyremote control again.

    5. Key in the four digit code for your brand of TV. The light on the Skyremote control blinks twice. If the light blinks once only, recheck the code for your brand of TV and start again at Step 1.

    6. Press the standby button on your Skyremote control. If your TV switches off, press select. The light on the Skyremote control blinks twice (code stored). If your TV does not switch off, press tv, then press the standby button. Repeat this (press tv, then standby) until your TV turns off, then press select (stores code).

    If at this point the LED on the Skyremote control blinks three times then all possible codes for that make of receiver have been checked. Repeat from step one, ensuring that you enter the correct manufacturer code.

    At the end of the sequence, if you see the TV Guide screen, the remote control setup process is complete. If you did not see the TV Guide screen, you must now complete the following steps.

    8. Press tv on your Skyremote control.

    9. Hold down select and the green button together for about two seconds, until the red light on the Skyremote control blinks twice.

    10. Key in the number of the channel on your TV that you use for watching satellite TV.

    11. Press select on your Skyremote control. The red light blinks twice. The remote control setup process is complete.

Note: The LG codes that Sky have provided us to work with our newer television sets are; 0037, 0056, 0060, 0065, 0080, 0081, 0125, 0137, 0178, 0191, 0204, 0244, 0245, 0275, 0318, 0389, 0391, 0398, 0405, 0459, 0502, 0742, 1146, 1367. We also have some older codes; 206, 037, 060, 065, 080, 137, 191, 244, 245, 275, 318, 389, 391, 398, 405, 459, 502. The codes are stored in a database of the Sky remote. If the above codes don't work you may need to buy the latest Sky remote. Otherwise it is a matter of waiting for the new Sky remote which may have the updated codes. Best regards, LG Electronics.


If none of the above codes work try this:

1) Switch on the TV set

2) Press the TV button on the Sky Remote

3) Hold down the select and red buttons for 2-3 seconds until the LED blinks twice

4) Press the standby button on the Sky Remote (The TV should go to standby)

5) Press select to store this setting

If the TV does not go into standby press the TV button then the standby button, then TV then standby, keep repeating this until successful.

Seems to be a handy way if you can't find the code for a TV.
It worked after about the 6th or 7th time hitting TV then Standby for me.

Sky TV REMOTE WILL NOT WORK MY LG tv RZ 37LZ55 ,NEED A CODE ....TRIED ALL CODES NON WORK !!


Hello Kenny

Please follow the steps below with you Sky remote.

TV,
RED + SELECT (flashes twice)
TV
0056

Try the volume button if this works then press the SELECT button on the remote. If not press the TV button and try the volume again. repeat this step until the volume works the tv then remember to press the SELECT button to save the code to the remote.

If for any reason this does not work then what I would like you to do is take the battery cover off the remote. You will see a label on there stating what REV 4,6,8 it is. The numbers indicate how old the sky remote is. If your LG telly is a newer tv then you may need to purchase a newer Rev sky remote.

The above should sort you out no Problem Kenny
When it does please leave a thumbs up

Cheers

No picture, no sound on a LG LCD tv


If it is hot were you live , That model of t.v doesn't like heat, anything about 35 degrees celsius could cause a problem with the card components.

You need to replace the inverter board if you can find the spare part. Otherwise you need to replace the whole lcd panel.
