    Thanks for your tips - I have/can use a multi meter, but have never worked on a tv before - is it possible to give some guidance on where to test? (We live remote and it will take some time to access a technician).

    The model number is: TH-42PV30 and serial number: YB4530084. Thanks

Hello stanton01, Sounds like a main circuit may have blown out from your tv, this usually happens because of voltage regulation, meaning that if the voltage is not regulater correctly it might have been affecting your Tv until it eventually burned out the video card. It is not that expensive to fix if you plan to fix it yourself, but if you still have warranty I would rather get a warranty replacement.
good luck!

NO VOLUME bars means your Display panel isn't even PRIMING (that's when the panel "gently lights up" before the video comes online)

That also means that either the X-sus, Y-sus or the Z-sus board isn't powering up the pixels....I doubt the power supply is faulty since you do get sound.

It is better u should take it to service center...

If this was a laptop I would say that the backlight has blown. What is the model number of your tv? and when was it purchased?

I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats...


  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

Blinking timer light and cannot turn on


How many times does the LED blink? Does it blink 6 times, pauses, and repeats? Or is it some other number of blinks? Or does it just blink continuously, once a second? (Note: on Mitsubishi's it is normal for the TV to blink rapidly for about 90 seconds after you plug the TV in, while the TV runs internal self-tests.) If the LED continues to blink continuously after 90 seconds, then the problem is on the DM board. There are 4 electrolytic capacitors, grouped together. I believe they are either 820 uF (mfd - microfarads) or 1000 uF at 16 Volts. If you check them, you will see that their tops are swollen (slightly rounded; not flat across). They will check okay with a capacitance meter or ESR meter, but don't believe your meter! Replace those 4 capacitors with either 820 or 1000 uF capacitors rated at either 16 or 25 volts. Make sure you use good, high-temperature (105 deg C) low-ESR capacitors. I recommend the "FM Series" capacitors from Digi-Key corporation, part number P12366-ND or P12379-ND. Less than $1.00 apiece. Good luck!

FLASHING POWER RED BUTTON 7 TIMES


I believe that is a bad power supply board. You can unplug set ,open the back access panel and look for swollen electrolytic capacitors they will most likely be slightly rounded on top instead of flat top like the others.Not sure if just replacing caps is enough we mainly swap out whole board.Some models' replacement power supply is slightly different from original in that a couple of the plugs are in different spots and require an extension cable.

Turn on the TV and only Timer light is on , no sound & picture


after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.
