Question about Panasonic Viera TH-42PX80U Plasma TV

2 Answers

My TV won't switch on. It goes green and clicks on momentarily then switches to stand by with red flashing light flashing 7 times. I've tried holding the on/off button on, unplugging it for a long time - no luck. Basically it won't engage. It is in standby mode and won't respond to the remote. PANASONIC VIERA THP42X20Z

Hello,

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

Good luck.

That happens when the power source has a short on one of its outputs and shuts itself down for protection. You need to open the tv , check for failed parts (as bulging or leaking capacitors) and test the voltages on the outputs. At least basic electronics experience is required. If you don't have it then call a repairman.

    Actually it's not in Sand-by mode, it's in protected mode. The power source must be repaired to fix that.

LG 17LX1R flashing red LED - TV won't power up


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Trying to program a direct tv remote to work with my 46" lcd, Vizio tv. Have tried the codes provided, but they don't show when I type them...not sure if actually being entered. Or, maybe have...



1 Vizio tv.code 0864 OR 10885 OR 11756OR 10178

Unable to Find Correct Code
If you were unable to find the code for your brand of TV or component, you can try a code search. This process may take up to 30 minutes.
1. Turn on the TV or component. Insert a tape or disk if applicable.
2. Slide the MODE switch to the TV, AV1 or AV2 position, as desired.
3. Press and hold the MUTE and SELECT keys at the same time until the green light under the selected switch position flashes twice, then release both keys.
4. Enter 9-9-1 followed by one of the following four digits:
Satellite - 0
TV - 1
VCR/DVD - 2
Stereo Receiver/Stereo Amplifier - 3
5. Press PWR, or other functions (e.g. PLAY for VCR) you want to use.
6. Point the remote at the TV or component and press CHAN+. Repeatedly press CHAN+ until the TV or component turns off.
NOTE: Every time CHAN+ is pressed the remote advances to the next code and power is transmitted to the component.
7. Use the CHAN- key to step back a code.
8. When the TV or component turns off, stop pressing the CHAN+ key. Then, press and release the SELECT key.
NOTE: If the light flashes 3 times before the TV or component responds, you've cycled through all codes and the code you need is not available. You must use the remote that came with your TV or component.

Verifying the Codes
Once you have set up the DIRECTV Universal Remote Control using the above steps, use the following instructions to find out the 5-digit code to which your component responded:
1. Slide the MODE switch to the appropriate position.
2. Press and hold the MUTE and SELECT keys at the same time until the green light under the selected switch position flashes twice, then release both keys.
3. Enter 9-9-0. (The green light under the selected switch position flashes twice.)
4. To view the first digit in the code, Press and release then number 1 key. Wait three seconds, and count the number of times the green light flashes. Write this number down.
5. Repeat step 4 four more times for the remaining digits; i.e., press number 2 for the second digit, 3 for the third digit, 4 for the fourth digit and 5 for the final digit.\


Depending on how you set up your remote, the VOL and MUTE may control the volume only on your TV, regardless of the position of the MODE switch. This remote can be set up so that the VOL and MUTE keys work only with the component selected by the MODE switch. To enable this feature, perform the following steps:
1. Press and hold the MUTE and SELECT keys until the green light under the DIRECTV position flashes twice, then release both keys.
2. Using the number keys, enter 9-9-3. (The green light will flash twice after the 3.)
3. Press and release the VOL+ key. (The green light flashes 4 times.)
Now the VOL and MUTE keys will work only for the component selected by the MODE switch position.

To Lock Volume to AV1, AV2 or TV
1. Slide the MODE switch to the AV1, AV2 or TV position to lock the volume.
2. Press and hold the MUTE and SELECT keys until the green light under the selected switch flashes twice and release both keys.
3. Using the number keys, enter 9-9-3. (The green light flashes twice.)
4. Press and release the SELECT key. (The green light flashes twice.)
