Re: Jvc lt-50e73

Got myself a programmer, reflashed the firmware and sound works now!

Re: Jvc lt-50e73



Okay. The firmware needs some kind of external flasher I guess? Atleast the USB update with the file mentioned on this topic did not work via USB....

Re: Jvc lt-50e73

Did you got the sound problem solved? I recently got same JVC unit, everything works, except sound. Got sound working few times when I did factory reset, but was gone after shutdown.

Re: LG Plasma 42PG6010

Hi! My parents had this similar LG 42PG6010 set for years, had to replace some blown caps once. Now it's starting to act up again When turning on, it keeps flashing red light and clicks for a long time before light changes green and no picture. If you shut it down after that and immediately turn it back on, it wakes up and works flawlessly. There is also 2 pink lines on the screen, other one is solid and other one is coming and going, depends what kind of image is on the screen.

I'm pretty sure the startup issue is once again some bad capacitors...

Re: Sony STR-DE445 wont go out of PROTECT-mode

Yup, it could be possible too. I take my magnifying glass and check everything with care, hopefully that will help.

Re: Sony STR-DE445 wont go out of PROTECT-mode

Still in protect mode, but what I discovered now, left and center channels have 12 volts, and the right channel has -46VOther thing I noticed, on the front panel there is A.F.D and 2CH buttons which used to show orange light, now there is only flash or nothing. I guess one of those big chips or both of them could be faulty?

Hi! I got Sony STR-DE445 for free because it originally had weird noises in front right channel, which would go away if you bump the connectors or the amp itself. So, I took it apart and fixed a lot of cold solder joints, and then put it back together. Well, now the amplifier only shows up PROTECT message and wont let me do anything I checked that there should not be shorted contacts anywhere. I also noticed when I turn on the amplifier, there is over 9 volts going to speaker connections(way over voltage I guess), and on the digital pwb, there is 7805A voltage regulator(IC1009) which...

Re: Samsung LE32B455 intermittent loss of power
