Bush 37lcdhd audio fine but picture loss , then nothing then picture back.?

Inverter board has failed. You can get replacement inverter by contacting the people over at www.tvcircuitboards.com

Check whether the 'Mute' function has been On. If it is On make it OFF. If there is no such problem, check the speaker and audio output section circuits inside the TV.

It sounds like the vertical output IC may have some solder issues. Often bad solder in the vertical circuit will cause the CRT'S ( Picture tubes) to shutdown for protection during loss of deflection and audio will continue to function. I would inspect the solder on the Vertical IC first.

I opened the cover, found nothing smoked or loose, no tweaks available, in short there was nothing I could do without diagnostic gear. All other sources in my system were fine, so simple substitution confirmed the problem was output of Teac dvd player. Taking it to a repair shop would be $50 up front for fix-or-not... So, I went to Walmart and replaced it with a Sony DVD player for about $40. Regret loosing the look of matching components with my Teac receiver, cassette player but it's job is to play movies. Fixtya!

first thing is to change the lamp

IT is the Y Sustainer board blowing fuses. IT has 2 fuses. I have worked on severl of this model and the Y Sustainer board goes bad and blows the fuses.

NO audio and no picture .... no power to on - off button. Checked outlet and it is good .... cable connection good - checked with another tv....
