SOURCE: TV freezes when switching to a digital channel

Issue was with the HD channels only.
Updated the firmware of the TV to ver 2.

Now the TV will stutter for a second when changing to a HD channel but it no longer locks up.

SOURCE: mintex 37 inch wide screen. remote is working however cannot change channel, input source or volum. only turns tv off. The buttone on tv doesnot work connot change input source or volume

Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

SOURCE: TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

SOURCE: hdtv picture freeze

I also have a Brand new Sony Bravia 52" LCD with Comcast Cable (motorola box).When switching between HD Channels sometimes the left side of the screen shows a smushed version of the new channel, and the right side is a frozen picture of the previous channel. I correct this by switching to a non HD channel and back. Cable or TV problem I wonder?

While watching a program the Tv keeps going to a Blue screen at least once a minute.

Hi. First check to make sure the HDMI cable is completely plugged in. If that isn't the problem most likely it's a bad cable or a bad or dirty HDMI input. If you can try another input see if that fixes it, if it does then the first input is bad, if not, then the cable or source is the problem.

Precision TV - PTV2548 no sound when your watching cable but there is sound forvideo input

may be the source itself(i.e. cable box) also check cables between cable box & TV. If you are connecting the DVD to the same input the cable box is installed, You know that input on the TV is OK. If you get no audio when the DVD is connected to the same input as cable box, then issue is the MAIN PCB.

My pc is connected to my tv using an hdmi cord, it frequently cuts out and says no signal

Sounds like either the laptop's hdmi output, or the tv's hdmi input is the problem. You can findout wich one by connecting the laptop to another set and see if it still happens. If it goes away then it is your tv input, if it is still there it is the computer.

Tv keeps changing the source of signal after about a minute so if i am watching cable tv on hdmi it switches to a different input i.e. ext connection after about a minute. it keeps going through the...

You may be the proud owner of devices that subscribe to the Consumer Electronics Control (CEC for short). These devices, via the HDMI cable, can read each others needs. If a CEC supported DVD is connected to your HDTV and the player is powered on, your HDTV will automatically change to that input ( eg: HDMI 2). Conversely if your HDTV is on and you change input to HDMI 2 the DVD player will turn on.

You could try the "masking tape over the TV's IR eye" to see if there is any extraneous Infra Red in the room that might be causing the problem? If it stops check for bright or shimmering light bulbs or Compact Florescent Lights (CFL's)

T.v. flashes off and on while watching it but doesn't do it when watching dvd's

I'm assuming that the source that flashes is sat/cab connection. If the cable types are the same between the dvd and the other source (both hdmi ?) then try swapping them. If not then purchase a cable to swap(keep the receipt and make sure you can return) to see if the problem goes away. If it is a cable/sat/dvr then try unplugging for about 30 minutes and plug back in. If that doesn't work, then try changing the input where the cable plugs into the tv . . . if its HDM1, then move it to HDM2 and make sure that you switch sources on the tv to new source . . .

When i switch my tv on it turn's itself to standby, i can switch it back on again but it just keep's switching itself to stanby after a couple of minutes.

You need a live input source to the port that the TV is set to, or turn on the tv and switch input to a live input source, anything else and the tv shifts to standby.

The possibility is that the HDCP handshake could not have happend correctly and hence the issue. Try to connect to different HDMI input of TV from Cable box. If possible change the resolution of cable box and check video

While playing xbox 360 in 1080p mod, the screen frequently blanks

Most TV's have problems doing 1080p over component. Dial the Xbox back to 1080i. Make sure the big switch on the Xbox AV cable is set to 'HDTV' not 'TV'(common problem) If the problem persists, try plugging into different hookups, use HDMI (if your console supports it) or buy one of the HDMI adaptors from PDP or MadCatz if your console doesnt. HDMI will reduce the clutter and will make 1080p a reality.
