Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

When i turn my television on it shuts off and then turns back on a few times without any picture but sound. we just replaced the bulb but that does not seem to be the problem because it did it again with...


Bulb? LCD tvs do not have a bulb it only has a panel with a backlight sealed into it. Is that what you replaced? The problem though is related to the backlight not coming on. This is due to a faulty backlight inverter board(replacement costs about 50$) which should be replaced to solve this problem.

How to replace bulb


Bulbs are not replaceable on flat panel TVs. They are part of the back lighting "light box" assembly. You would need to replace the entire LCD screen.

Hearing sounds but no picture model #CS35505


if this is a LCD TV u most likely need to replace the LCD screen backlight, this highly specialized flouresent bulb is about $500 installed, I strongly suggest u have it done by TV repair tech, as there are adjustments that may need to be done as well as other parts parts like the bulb socket that may need to be replaced.

No backlight on Samsung 710N LCD Monitor


No, it is not easy to change the backlight on an LCD panel. The backlight is an integrated part of the LCD panel itself. The backlight for LCD monitors is also model and manufacturer specific, so there's no easy place to order a backlight to do it yourself. The good news is that your Samsung monitor should come standard with a 3 year warranty, so if it's less than 3 years old, you can call Samsung and they'll repair/replace it for free. If it's over 3 years old, then you may need to repalce the monitor... or pay to have it repaired.

Bulb keeps going on and off . does that mean the bulb is going bad


Hi,
If TV shuts off and turns On itself again then yes, bulb in TV is weak and need to be replaced.
Please buy Sony oirignal bulb/ lamp for your TV safety.
Lamp/ bulb replacement procedure would be written in user manual.
Thanks.

How to replace lcd tv bulb


Most of those models you replaced them through the front. The lower front panel pulls off. Some models have a knob that must be loosen on the back of the set at each end. Once the front panel is taken off the Lamp door is easily accessed. The new Lamp from Sony will come with the proper Wrench to remove and reinstall lamp.
Hope this helps,

You will need to replace the whole in-dash A/C control unit. Changing the small bulb won't rectify your problem, as the display is LCD.
