Question about Westinghouse LTV-27w7 7 in. LCD HDTV

1 Answer

Previously, I described the situation as "Blue light is on, but TV does not respond to remote power button, or manual use of power button on set..." Since then, I realized that the blue light does not come on when set is plugged-in, until either the remote or the manual switch is pushed. The blue light then stays on, but the set seems to make no further response. Where should I look for the problem?

Power supply module will be the first place to look, look for bad DC filter caps, cold solder joints. Need to find out if all the output voltages are OK. Right now the standby 5vdc and the processor are partially working.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

What your describing is symptoms of a power surge, Many LCD Tv's are sensative to Slight fluctuation in power during rain, thunder and lightning storms, i myself was happily watching Tv through such a storm at one time, and when i went to bed the TV would not respond remotely or manually, i also disconnected the power from the wall waited for the ready light to disolve and try to turn on, unfortunatley the damage was done, a Tv Repair was nessecary and since then i now use a belkin power surge protector board for my TV and appliances......one question to you is i would guarantee you do not use a surge protection my friend......and your set will need a Tv Repair, it is not major as what is neccesary is a firmware dump on the internal memory and replace the BIOS Battery as well.

  1. Manually turn ON your device (TV, VCR, Cable Box)
  2. Press and "HOLD" CODE SEARCH
  3. Press and release the device button you want to set up (TV, VCR, Cable Box) However, if you are using AUX for a device, press and release AUX first and then the device button for the type of device to be programmed (TV, VCR, or Cable). The selected device button will flash once.
  4. Release CODE SEARCH.
  5. Press OFF/ON repeatedly until the device turns off (you may have to press up to 100 times at a rate of once per second).
  6. Once the device turns off, press and release ENTER.
  7. With the device on, press any other button. If the device responds, no further programming is required. If the device does not respond, repeat steps 1-6.

The internal power supply is failing. You are having to "shock" it into operation by plugging and unplugging.

My remote will not turn the tv on or adjust the sound, it will change channels


First, try pressing TV on the remote, check if that solves the problem. Then press Sat and try the TV power button again. If the remote previously controlled the TV, you lost the code for the TV. If you have your Dish Network manual, check if you wrote down the code when it was originally programmed. Which specific remote/receiver do you have? The programming directions and code lists are available here: http://www.dishnetwork.com/supportsection/remote-setup . You can also scan all of the codes to find the correct one: see http://www.dishnetwork.com/SupportSection/power-scan-instructions . Additional remote/receiver manuals are here: http://www.dishnetwork.com/SupportSection/manuals .

The direct coding procedure for the Dish remote that I have is: while facing the TV to be controlled (after adjusting the key for TV1/TV2 in a multiple TV system), press and hold TV until all four indicators light up. Then enter the 3 digit code. Press and release the # key. Then see if the code TV powers off when you press Power. Then press Sat and check if the TV power button works. Try additional codes if the TV doesn't respond.

If you recently got a new TV and you tried to program the remote for your TV, your dish remote may not have the code you need. (Most universal remotes are limited to codes for devices released 6 months or more before the remote was programmed.) In that case, you should use the TV remote (and see if it has an option to control the satellite receiver). Alternatively, get a new universal remote that will control all of your devices. (The remotes that can be programmed by USB are the easiest to set up.)

I hope this helps.

With a non responsive remote that would be inpossiable you need to replace the control board inside around $100 bucks then you can have a good tv again but to get to the service menu your controll has to be working.
