Tools needed for the repair. 1 small screw driver and 1 small plastic pry bar. you may also need the use of a small solering iron to seperate the power supply wiring from the main board assembly. There are usually small screws in the back of the unit that must be removed first. When all the screws are taken out you must use a small plastic pry bar to separate the top and bottom sections of the remote. This will usually expose the electronic switch pad that is used to do all the interaction with the electronic controls of the remote.Below these keypads are the actual switches that perform the function. This is usually a small circuit board with a small battery operated power supply on a main circuit board. This is the board that will be having the problem with the control. You should test it first to make sure the malfunction is not some mechanical problem between the switch cover and the switches. Also check the switch to make sure the point of contact is clean and clear .IF this is all working fine. Then you need to replace the unit. The switch is probably damaged internally and cannot be repaired. Replace the switchboard with the new one and reconnecting to the battery power supply. Putting the unit back together by reinserting all the screws.You should now have a functioning remote control. I hope this has helped you with your problem.

Proscan 26LB30Q Vs PS2 = HELP


The red white and yellow cables are composite connections. The red/green/blue connections are component connections.

The playstation's composite connections consist of two audio connections- red & white, and a composite yellow video connection. The TV's white connection is the audio, and the red/green/blue are component video. You need an adapter that will connect the one yellow(composite video) to the three red/green/blue (component video) connections

Just try to reset;

Resetting the TV
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can saved time.
1. Unplug the TV power cord from the power outlet for 3 - 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

Channel changing on PROSCAN 32LA25Q


I had the same problem, what fixed it for me was to set auto scan to setup all the channels for me again. Another thing to check would be whether it is set up to use CATV or AIR.
