Having problems with your Flat Panel Televisions ?

I have not serviced one of these models before, 26XR9DA. The problem is no Picture Sound OK. The Bachlights come on for about 3 Seconds with Sanyo LOGO visible then go off with the High Voltage inverters powering down. 5 12 and 22 V lines are clean and steady I have changed a few electro caps but this TV seems too new for the common caps problems The B ON pin sits at 3.2 Vs and never changes during startup etc. Im hoping there is a common fault for this symptom. Any help is most welcome

Hi mroulston,\015\012
\015\012First check the brightness of the logo when it's first come on, you will notice that there was a slight changed in brightness if the one of the backlights was already busted. This is the very common fault I've encountered with the symptoms you've stated.If one of the backligths failed, it will produced an overload to the high voltage transformer and caused the subsequent shutdown. Busted backlight has a blackened end and can easily identified.\015\012
\015\012Another was the inverter board gone to overload. More prone to this fault is the high voltage transformers(secondary side). You're inverter board has more than one high voltage transformer, using the multimeter, compare the resistance of the secondary side to one another to determine which is the faulty one. Check also the driver transistors, fusible resistors around(low resistance resistors)...\015\012
\015\012Hope I helped you.\015\012
\015\012Have a nice day!\015\012

I was watching T.V. and when I went to change the channel, the remote control wouldn't respond. I changed the batteries (generic) & the new ones didn't make the remote work either. I hit the power button on the T.V. and it did turn the T.V. on & off & changed the channels. I think the bulb or the eye on the remote is the problem. I can't remember ever seeing the bulb actually lit up. It is dark, so it seems it would be red. It's an old T>V> & remote, but has always worked. HELP PLEASE.


You won't be able to see the light from remote's LED (Light Emitting Diode) because it is IR (Infra Red) which is invisible to the human eye.\015\012\015\012Try re-entering the code for your tv to see if it works.\015\012\015\ ... Flat Panel Televisions

We have a Toshiba 42HM66 DLP. It is at least 3 years old and the lamp had never been changed. Lately the picture has gotten darker and once the unit is on for awhile the picture starts flickering and colors are not right. We assumed it was the lamp. Changed the lamp and still the same problem. Called Toshiba, they could not help but said picture flickering is not a symptom of needing a new lamp. They suggested we call a tech and they gave us a reference. The tech came out and agreed the
