Our problem is that the red light flashes 10 times and then it turns off we can hear sound but cannot see a picture we have turned it on with a friend on an outside antenna and it works but through...


If you were able to get it to work with one signal source but not another, the poblem may be with the foxtel cable rather than the tv. Was there a difference between the connection from the aerial antennae and the cable? Have you checked to make sure another tv works on the cable from that location?

Olevia 242 TV.... No picture or sound!!!


A blue screen usually is present if no signal is connected to the set---hook a DVD up to one of the rear inputs--select that input and see if have picture and sound.

If that works connect cable or antenna to set and select that input

NO signal is like no gas in car---it will not run.

1 Check the antenna/cable connection 2 Connect the TV to the AC power outlet and press power button on the TV 3 When the indicator light(standby) lights up in red, press the on/off switch on the remote. 4 If this does not work, reset all settings to factory settings by going through menu and selecting settings

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Unit makes sounds but no display


Hi
If unit is as per pic I assume it has external antennae. Ensure the multi pin plug is secure in the rear of the unit and also use a fully charged 12 volt battery, Has it been working before?? Usually a rear plug problem. How old is unit. Just had a another thought, check that the polarity is correct, ie pos wire to RED (Pos) on battery. Very polarity sensitive.

Red light flashing, no picture/sound!!!!


HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.

FUSE CHECK LIST--

3A 12v- fuse----(242208600623)
SM 3A 125v-fuse----(242208600657)
500 MA-fuse-----(242208611092)

Thoroughly check your antenna connection, be certain the plastic grommet is in place (and not cracked) between the bottom of the antenna adaptor stud and your antenna mount, and check for corrosion in and around your antenna connections. If using a fiberglass antenna, check for cracked outer insulation. If a whip, be sure the Allen screws are tight and the antenna is getting a good connection. If you have a base-loaded whip antenna (Wilson 2000) make sure the base coil plastic case isn't cracked. If you find anything wrong, invest in a new antenna. If all that checks out, buy a new 18 foot piece of coax (around $20, or get the best quality you can afford) and run it to the antenna. You may have skinned the coaxial shielded outer insulation somewhere in the uninstall/install process, it only takes one tiny break to cause problems. Be sure not to run the coax through the door jamb or a window where it WILL be pinched and cause trouble, take time to run it under the dash and out a permanent vent access or through the firewall.

No picture or sound


When the red light is on, can't you turn it on by pressing channel up on the set, or power on the remote? If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Its possible that a capacitor has gone bad. You'll need to work on that, and then readjust the set. Not a major repair. When you open it up look for dry soldier joints and resoldier if necessary. good luck
