Question about Sony BRAVIA KDL-52W4100 52 in. LCD HDTV

2 Answers

Picture & sound go off for 1-2 minutes, then return.

Sony KDSR50XBR1 RPLCD - Picture and sound go off after set has been on for 5 minutes. Standby light blinks rapidly, then sound and picture return. Repeats in about 3-5 minutes. Checked all the input connections (cable, DVD); did a reset- nothing helps.

The most likely the TV has a power supply related problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Hi!

Please try disconnecting all the cables from the TV then reconnecting them back after a few minutes. You may also try connecting the power cord from the TV directly to a functional wall outlet. If the issue persists then the projection lamp needs to be replaced.

We keep losing sound and picture on our TV


If you haven't replaced the lamp, it is almost certainly time to change it. A weak lamp will cause the TV to play for a short time. As the old weak lamp heats up, it draws more current, and the reflector in the lamp, having become cloudy over time, converts the light into more heat rather than reflected it out into the set. Eventually the lamp draws too much current and the set turns it off, going into a restart cycle. Buy an original Sony lamp, as the aftermarket replacement lamps are known trouble makers. Be sure to rate this solution. Thanks!

Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks
