    the tv works fine but will not turn on. when the power is turned on with the remote power switch or by tv on/off switch, the green power light will come on for a few seconds then switch off. I can repeat this ten or so times until the tv finally stays on. is theis the same problem that can be solve with a new power unit and where can i get one?

Need to find code for Jumbo Universal Remote to use with Aiwa S2011 MTS television. Thanks for any help!


Hello
Aiwa TV is not lited on Jumbo Universal Remote codes. Anyway try out with these codes. Sometimes may help you.

Three digit codes for Aiwa TV with universal remote are:
195/ 196

Four digit codes for Aiwa TV with universal remote are:
0195 0196 0227 0269

Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.
Code Search If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.
  1. Manually turn on the device (TV, VCR, etc.) to be controlled.
  2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
  4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
  5. Press and release MUTE to install the code. The indicator light goes off.
Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.

NOTE: Switch OFF and switch ON your TV with its FRONT PANEL POWER ON-OFF SWITCH each time before trying an other code.
OK

What was the code did all work cause i can not get it to work at all


Hello

Just try one amoung the following codes. I've only these three codes are available with me for Jensen Tv.

{ 0004 _0009 _0133 }

Proceedings

  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.
Note:- If one amoung the above four codes did't work, try the other after the TV is switched off and switch in again after some time, say at about 10 seconds, and try the other. Not enter the code continously without turning it off, after one code won't work. Ok.

When I turn my TV on, it clicks on and off 5 times then stays off


first check a switch contacts, that switch has two make contacts in side it. if the switch is okay, then check a power supply dry joints on it.
or a dry joint on the line out put transistor, or a line transformer legs.

SHARP 29" TV switching off to Standby


have you tried changing the batteries just to elimate this problem

change them

sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),

your tv gets confused and then switches itself to standby

if you have changed the batteries and this problem still persists

it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv

PSU'S generally 20 to 50 pounds depending on model

don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)

hop this helps mate, let me know how you get on

TV Switches itself back to standby mode continuously


if your remote is ok then this is due to power supply failure in your tv. either it is loose in oscillator ckt in switching section or it has failed. if not tech person call tech to fix it. not a major problem.
