Having problems with your Flat Panel Televisions ?

My tv will turn on but no picture of sound will show. The screen is completely black. When I press the power button on the remote the standby light on the tv blinks red twice then a smaller than usual blue circle appears.



Answers :

Hi,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

I hope this will help in solving the problem....
Tv turn on now,have a flashes of a picture a few sec.before it is dying,than have sound left only?Yes,than those 2 long boards that call the LCD inverter board are dead.Those 2 long LCD inverter boards help the LCD screen panel to have a backlight to produre a picture.Tries websites like Shopjimmy.com.Ebay.com to buy those refurbihes 2 long LCD inverter boards for the replacement.

Hello, I have a Toshiba 57H84R rear projection tv that has developed a problem. Occasionally the screen would turn bright blue for a couple of seconds and then go blank (dark screen, like it had shut off). The red power button would go from a steady red light to blinking continuously and would have to be unplugged, then plugged back in to get it to come on again. One time it did this, there was a bright blue circle in the center of the screen and now there is a permanent yellow spot in the cente

My JVC HD56G786 rear projection tv is not powering on anymore. I have recently replaced the bulb (as I've done once in the past) and it worked fine for about 4 weeks. This weekend it began powering off on its own after being on for a couple hours and the blue and red lights would flash rapidly simultaneously. Now it won't power on at all- it begins to power up and then immediately shuts down and the lights blink rapidly. The bulb appears fine, but the owners manual says that this issue arise


It may be a fan or a power supply issue, as you said.If there is a fan or other cooling device near the bulb, make sure it is operating. If it is not operating, replace it and see if it works. If it is a fan problem, you will notice becau ... JVC HD-52G786 52" Rear Projection HDTV
