Philips 36RF82S / 36RF82 Q800 No power, no Sound or pic

Hi Guys

I have a Philips 36RF82S TV and it had the following symptoms before it went dead.

-initially the remote stopped responding after 10 minutes or so

-and then it shuts off randomely,

-sometime it finds it diffuclt to tune it self and

-some time the picture is bigger then normal and some part of it is
missing -from the edges as if the picture has gone in to higher
resolution.

Only soultion was to shut of the TV from the mains ( absolutely no power) and wait for 5-10 minutes and turn it back on.

Some times the pciture will stay for hours and some time it will go in 10 minutes.

After few days the TV will not power on at all with no standby lights what so ever.

I have the service manual with board schematics and from the latest symptom it seems its a power supply problem. I have little expereince with electronics so what I have found is as follows.

- It seems the AC to DC circuit part of the PSU is off by 10 volts or so. I was measuring the voltage at one of the testpoints on the schematics. In the schematics it said the standby volatge should be 158 volts DC but it shows 170 DC on my multimeter. Not sure if this is normal or if its within the error limits. I also measured the voltage accorss the GBU4JL-7002 bridge rectifer in AC-DC circuit and it showed 170v.

It could be the diodes around the rectifier.....

One thing I would like to mention is that when I plug the TV in power socket I can hear a minute sound from the picture tube. Its the high pitched sound that you hear normally when you power on a CRT TV. In my opinion its the sound of the voltage applied to the degausing assemply/circuit.

If some body experienced can guide me on this that will be geat. I can also email the service manual if the need arises.

Thanks and Best Wishes
