The tv turns off befor I get a chance to press any buttons.

1. Using Programming Codes

Find the TV code for your TV in the list from the Platinum Remote Control User's Guide (See References). For example, if you have a Kenwood TV, the three possible codes to try are 506, 573 and 712.

Press the "TV" button on the remote. Hold down the button until the "Sat," "VCR" and "Aux" buttons light up. Release the "TV" button and it will be flashing.

Enter the first code using the keypad. If you want the remote to control all functions on the TV, enter the code and press the # key. The "TV" button will flash three times.

Press the power button to turn off the TV and turn it back on again. If the code was correct, the TV will turn off and on. If the TV doesn't power down or back on, follow Step 6.

Try the next code from the list. Follow Steps 2 through 4 using each code until one turns off the TV.
2. Programming Without Codes

Press the "TV" button on the remote. Hold down the button until the "Sat," "VCR" and "Aux" buttons light up. Release the "TV" button and it will be flashing.

Press and release the "Power" button on the remote.

Press the arrow up key and stop. If the TV doesn't turn off, press the arrow up key again. Continue pressing the arrow up key until the TV turns off. Do not go fast when moving through the codes or you could miss the correct code. Press the arrow key and wait at least 20 seconds to see if the code works before pressing the arrow key again.

Press the # key on the remote when the TV turns off to lock in the code.

Here is a way with out the code.
1. Turn on the component (the tv, dvd, etc). 2. Press the TV (or DVD) button first and then the on/off button and hold both until the on/off button remains lit. 3.Press the PLAY button every five seconds until the component turns off.

• Each time the Play button is pressed, the illuminated ON-OFF button blinks ten times and a block of 10 codes is sent to your component. This process continues until all the codes in the Code Lists have been searched. If the component has not turned off after all codes have been searched, the illuminated ON-OFF button blinks four times, turns off, and the Auto Code Search Entry method is exited

After the component turns off press the REVERSE button every 2 seconds until the device turns back on. Skip to step 7. 4.

• If your television is an older model it may want to turn on immediately before you get the chance to press reverse. If that is the case and the TV automatically turns itself on then simply follow the step and keep pressing reverse until the component turns OFF. Then skip to step 7.

If the component does not respond, continue to press the REVERSE button EVERY TWO SECONDS UNTIL THE COMPONENT TURNS ON again. This will isolate the correct code in the last block of codes sent. Each time the REVERSE button is pressed, the illuminated ON-OFF button blinks. 5.

• If the REVERSE button is accidentally pressed after the component responds, press and release the FORWARD button. Wait two seconds to see if the component turns off again.

6. To save the new code, press and release the STOP button.

Good chance it took out the str regulator in the power supply.

I had a problem similar to this. I fixed it by toggling through the top buttons on the remote control. Sometimes the wrong button gets pressed and the remote cannotcontrol the unit it is supposed to. i.e. make sure TT320 remote has good batteries and then make sure if it has other buttons on it like TV, cable, DVD etc that the correct one is pressed to control the TT320. My TV remote would not control my TV and by chance my kids had pressed the satellite button so I had to press the cable button and then the controller startedto control the TV again.

Usually the PiP button scrolls through the PiP modes, so your best chance is to find the button that did it and give it another press or two. If you're unlucky, you might find that on the original remote the button to turn off PiP was a seperate one that doesn't correspond to the universal remote... In this case, try unplugging the TV fro the power and leaving for a few hours before turning on again. This might reset the PiP setting.

Chances are the Power Supply failed because the Horizontal circuit failed. It would not be out of line if the repair cost ran 250.00 plus.
It is probably not worth fixing due to the age of the set.
Hope this helps,

the instructions are on the back of the remote. if lost. you have to:
1) Turn tv on ( i would suggest turning it off then on)
2) Press the Device you want to sync (tv)
3) Press and hold the setup button it will blink once...let it blink twice before you go to the next step.
4) press 9-9-1
5) press the power key on the remote
6) press the channel up (CH +) button repeatedly until the device (tv) turns off.
7) when it cuts off immedieately press the setup button.

Pretty good chance the power supply board is bad. A number of capacitors will become leaky and you lose all power. Some techs still know how to do component Laval service but most just change the board $$$$

Hiya this is how i got mine to work.Manually turn on the tv.
Press and hold setup on your remote till the light comes on and stays on.
Then press the tv button then release. The light will flash then continue to stay on. 
Now press and release the power button waiting 2 seconds before you press it again until your tv switches off.. you may have to press it for awhile.
Once your tv cuts off press the mute button and now your remote is set for your tv. 

Yes there is search mode, but unfortunately you have to look in the manual. I am using 3 universal remote controls (one from sony) and all of them have different procedures for entering the code or searching for the code. The idea is, once the rm is in search mode, you have to wait until the TV turns off (or no) and you have to stop the search and save the setting. If you have no manual and the code is just 2 digits, you can try the 99 codes. This may take you maybe an hour or so (better than nothing). If it has 3-digits, it's a problem.
