Question about Televison & Video

Open Question

JVC Models AV-27WF36 and AV-32WF36 went out during thunderstorm. Neither set has power beyond the switched mode xformer. Factory service manual shows no voltages on any component. 27" will operate intermittently - not so with the 32". Relay driver transistors (darlingtons) did not measure properly. Both have been replaced.

SOURCE: power supply

you are so lost... a short in anything after the power supply will shut down the horizontal driver signal. first check to see if horizontal output transitor is shorted. If not it should have about 110 volts dc on it. if not go back to Power suppy ...many things start here...check to see if you micros got power a 5v heatseeked regulater is common bad. also the startup circuits can be tricky...in the power suppy. I look for a kit online for power supplies ...they give you about every that fails. or you can start buying boards...best bet it is take to a professonal for you my freind havent a clue. CrazyLarry

Power Went out for a minute and TV needs to be reset!!! Lock Mode Problem


Hi,

Do the reset test.I give this 50/50 chance of clearing it up. Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.

Goodluck,
Please don't forget to rate me as fixya..

Hello
Just make the picture status button on the remote control and get the display setting to its factory mode.

The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only)
Press the VIDEO STATUS button repetedly to get these choices.

Flashing On Timer


This is usually an indication for a scan failure, and or high voltage failure. Also, the power supply may be damaged.

Depending on the nature of the failure, this type of service can be sort of expensive. I sugget to get an estimate before deciding.

TV WONT WORK AFTER THUNDERSTORM


From our experience, ther may be a power supply failure, or one of the scan circuits have failed. The fault can be one of many possiblities.

The set will need shop service.

Tv wont power up makes a noise but no picture


Your power transformer is likely shot. It'll cost at least $200 to have it replaced. Someone can come to your house to diagnose it. Usually costs around $65.
