Tv doesn't want to start

The instructions on letting the Hipi remote to seach for the code that came with my remote are not correct. I used the instructions from HOWTO.COM and printed below. There are two changes from the printed instructions. The first is to push the <TV> button after the <Code Search> button. The second is that the <Enter> button saved the code not the <MUTE> button.

Instructions
1
Turn on the Vizio TV.
2
Aim the Jumbo Universal Remote at the Vizio TV and hold down the "Code Search" button on the remove for roughly 3 to 5 seconds. The LED lights on the Jumbo Universal Remote will come on.
3
Press the "TV" button at the top of the Jumbo Universal Remote.
4
Start pressing the "ON/OFF" button repeatedly until the Vizio TV turns off. (This took only a few tries for my Vizio TV)
5
Press "Enter" on the remote immediately after the Vizio TV turns off to save the code.
6
Test the Jumbo Universal Remote by trying to control the Vizio TV with the remote. If the control doesn't work with the remote, repeat the entire process.

Ur tv have problems,etheir the Tuner signal board or the LCD inverter board.After u turn on the tv,no picture turn tv off/on 3-4 times each time wait a few mins.see if the picture come on?Than it ur Tuner board have problems.If u turn on the tv and get just a flashes of a picture about 30 or 40 sec.than just disappear,than ur LCD inverter board is the problems it dead.

If you hear a squeeling noise, then that would be your color wheel. When you replaced the lamp, did you reset the lamp hours? Did you check the power from ballast with a voltmeter to see if you are getting power to the lamp?

If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.

dear,
check the flyback. did u hear any noise coming from that ..

regards

looks like the color wheel its bad in the set,color wheel its not spining at its proper speed( one of the segments may be broken)
thats the vibration you are hearing.. and the set its trying to turn on..until you replace the wheel you will be able to watch tv again.

if the lamp has dies alot of the time to can look inside the lamp and see if it exploded (not always) do you get blinking lights?

If it's between 5-10 secs, that's normal. You will turn the tv on and hear a loud (buzz/hum) that is the picture tube firing up, once it's fired up, it has a few more seconds until your picture comes up fully. That is about 5-10 secs from pushing the power button.

If it's taking longer than that, your picture tube may be going out.

I had a 36XBR250 and it took about 10 secs to fire up and show a picture, and it was 5 1/2 years old.

try changing the channel with the original remote or by the tv's physical controls. It sounds like it has switch to an AV channel.

You can try this on the remote in standby mode, meaning tv plugged in but set off. Press Display,5,vol+,power on remote.Press each button within a 1 sec interv. Next the CRT display the item being adjusted. Press 1or4 on remote to select item. 3or6 to change the data. Press Muting then Enter to write into memory. Service Reset muting green enter red. Press 8 then enter on remote to initialize. turn set off to exit. wait least 10 sec. before turning back on.
