There is sound but no picture and after a while the television switches off into idle mode

Hi Carl
Good... nice to see someone knows about Caps.
If Switch Mode Power Supply is working OK
Then it can only be bad Connectors orMotherboard failure.

Warranty???

Hi! the trouble indicates that your television's picture is the culprit, have your unit check by a qualified technician for verification.

sounds like the crt is shorted causing the hot to short

Replace ysus board!!
Check all supply rails before replacing,

Cheers

hello

NIPPON computer grade

theres this panasonic tv that when i turn on it shows no picture and sound and makes a noise how can i solve that problem?

Probably need the TUNER either fixed or replaced.

It sounds like an eeprom issue. But you can try to reset the set. Turn the set off by the main power on the set. wait a minute or two then together push both the main power button and the standby power button. This should resett the tv. If that doesnt work you will need service as the zoom and the various modes are all controled by the eeprom. Only hold the two buttons for a second. sometimes you will hear the crts discharge while resetting.Hope this helps

1.service mode before putting unit into the service mode, check that customer adjustments are in the normal mode. use the reset function in the video adjust menu to ensure customer controls are in thier proper(reset)position. 2.service number selection once in the service mode, press the channel up or channel down button on the remote transmitter or at the set . the service adjustment number will vary in increments of one,from "S01"~"S19" to "M05". select the item you wish to adjust. 3.data number selection press the volume up or down button to adjust the data number. to enter the service mode. while pressing the vol-up and ch-up buttons at once, plug the ac cord into the wall socket and switch on the main power. now the TV set is switched on and enters the service mode. to exit the service mode, shut the television off by pressing the power button.

Im sure by now you have your set fixed sorry that you did not get a sooner reply on your problem but if you still need any help at all please let me know,Thank You for using FixYa and Have a Nice Day.
