Front power indicator blinks, clicking/high pitch sound
TV was working fine, then the picture flashed black a couple times like the cable was going out then went black permenantly. Tried unplugging for 30+ min. Still, front power indicator blinks. Removed rear panels, several LEDs are lit/blinking: DP06 Solid Red, DP23 Solid Green, DP35 Blinking Green, DP11 Blinking Green, DP37 not lit at all. Hoping these are diagnostic indicators. Is this an easy fix, or is this pretty involved? Buy service manuals? Buy schematics? Manufactured June 2001. Thanks!

Re: Front power indicator blinks, clicking/high pitch...
This how to is to repair hard drive, software and some firmware
issues that can arise on specific cable DVR and DAC and DCT boxes,
First instructions are for Scientific Atlanta hardware. Firstly,
one should be certain that the cable box has the coax (cable
antenna wire) hooked up to the CABLE IN or RF IN on the box itself
and be connected to a "hot" outlet - one that you KNOW works. Test
it by connecting a TV directly to outlet. If you get a weak signal,
the box will too. Digital boxes require a clean SNR. Remove in-line
"surge protectors" on the coax. These prevent the signal from being
sent by your cable provider to your box.
Scientific Atlanta DVR or High Def boxes:These need to be
"booted" or reset when certain errors occur. No audio on certain
channels when SAP is NOT set to ON and confounding error codes that
one can't seem to get out of. Common yet confounding errors
are : No Audio on DVR Playback. No Audio on Certain Various
Channels (ruling out SAP which can be enabled through the box, OR
the television set itself) there are easy ways to test. If some
channels audio is in Spanish when they are normally in
English...the obviously you will check SAP first.
Disc errors. On screen error on your TV that says something
like..."there are problems with your storage disc.." or upon DVR
playback instead of playing your program it loops upon itself and
two different steps to reboot box: Simultaneously press VOL+
VOL- and "INFO" buttons on box itself, not from remote. Box will
then display "bOOt" and shut down totally. Do not press ANY buttons
or try to power on said box. Wait for the correct time to display
on the box. This process can take anytime from 40 seconds to hours,
depending on how fast the cable company's servers are responding at
that moment and whether or not you have enough of a cable signal to
fire up the download process. If you call customer service for your
provider if this does not work, most likely a truck roll will be
run for a tech to come out to your residence to fix the signal
When the correct time display is on the Scientific Atlanta box,
THEN power on box and problems should be solved. An alternate way
to reboot box is to simply unplug unit from power supply and
replugging it in. Simply powering it on and off with the POWER ON
button will not solve anything.
On a Motorola box and/or DVR, the easy VOL+ VOL- and INFO will
not work to reboot. Remove AC power plug from wall socket and wait
30 seconds to a minute while box is powered ON. Plug back in to
wall socket.Box will "do it's own thing" and power itself on on
it's own after the cycle has been successful (30 - 60 seconds) and
the box should power itself back to the ON without you doing
anything. Time will not display on Motorola"General Instrument
boxes unless you set it up to do so in the settings mode.
Common IControl/On Demand errors:
MOTOROLA BOX Error 225 : A billing lock to prevent you
from ordering pay per views. If your account is past due, or if you
have an order to move to a new address in the service provider's
"system", this is a preventive measure to keep customers from
loading up tons of expensive pay per views and skipping out. Your
cable company cannot over-ride this error. If you are not in above
situations, your provider can "up" the limit on the box and clear
it so you can order PPV through your remote control.
SCIENTIFIC ATLANTA: for above mentioned error code, your SA box
will display not a code but a prompt to contact your provider by
telephone. Same issue.
MOTOROLA BOX ERRORS 204...203.. 207..these may be easily solved
by simply reseating the coax and then rebooting box.
SCIENTIFIC ATLANTA ERRORS 2207: reboot box. This is a general
code meaning the box has lost contact with the server. All of your
iControl /On Demand orders come through your local cable head-end's
servers. If and when it gets overloaded and times out, error
2207/207 will happen. Most of the time this is temporary. Reboot
box, try again in 15-20 minutes.
DVR BOX not displaying/recording/playing items:
Reboot. Good chance of fixing.
If your TV displays "One Moment, Please. Your Channel Should Be
Available Shortly..." this is a SIGNAL issue. Reseat the line
running from wall to the CABLE/RF IN on the box and at the outlet
at wall. If no joy, call cable operator.

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.
The power supply board have fail badly,all that high pitch screeching sound,it came from those high voltages gaps from those tranformers,that giving ur tv high voltages.The power supply board,that the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

This solution from troylove solved my problem.troylove11 Rank: Wiz Rating: 85%, 1164 votes
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.
my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up. latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.
Funny to see this because this is exactly what is happening to my 32 inch TV and I was researching to see if some one else had this problem and right away I find this, I've had my set for over a year now, and I have no solution at this time, but I will continue to research this, I figured that Protron would blame the cable company,that's what company's with crappy products usually do. Blame someone else.
