Poloroid 42" lcd - high pitched sound from the

This is not the power supply. HDMI has several versions. Cables can be mismatched to the version. HDMI also has a very sensitive input and can pick up any outside interference if you have long cables.

A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

try to adjust your resolution to the highest level, ps3 is a very high grapics device..

thanks.

If you are using a generic HDMI or a DVI cable, you will have to provide a optical audio or composite audio cable as well. Only high end HDMI cables transmit video and audio.

something problem with your connection from cable to tuner, if in good contact. you need to remove back cover and re solder tuner ckt board side. specially in 32 pin ic.

We had the same problem. What we did was unplug our DVR box from Comcast to reset it and plugged it back in and the picture came back.

Some of these sets have to run seperate red and white RCA cables along with the HDMI. I know it sounds silly but it is the truth. Look for audio inputs on the back near the HDMI port.

It's in the repair shop. I'll write back what the problem was and how much it cost to ship.

see if you can get a main total assy. or main board . i think the micro went haywire

FROM THE TOSHIBA MENU, (FIRST MAKE SURE YOU ARE SET TO
THE HDMI PORT THAT THE XBOX IS PLUGGED INTO) THEN SELECT
HDMI SETTINGS, UNPLUG HDMI CABLE FROM THE TOSHIBA TV (LCD
FLAT, MINE IS A 42") WAIT FOR THE SETTINGS TO HIGHLIGHT OR NOT
BE GRAYED OUT, THEN TURN OFF THE THREE SETTINGS, FOR COLOR
AND LIP-SYNC., SCROLL DOWN AND PRESS THE RESET BUTTON,
WAIT FOR MESSAGE TO APPEAR. TURN OFF THE TV AND PLUG IN THE XBOX.
TURN EVERY THING BACK ON. SEE IF IT WORKS.
NOT ALL CABLES ARE THE SAME AND NOT ALL TVS ARE THE SAME.
READ THE TV OWNERS MANUAL CAREFULLY, (RTFM), I FOUND A NOTE ABOUT
THESE SETTING ON THE SPECIFICATIONS PAGE.
