Hi there.

The problem you are describing points to defective electrolityc capacitors
which form part of the start up crcuit in the power supply.
The culkprit capacitors are small and usually hide between heatsinks.
these heatsinks get very hot under normal operation and dry out
the capacitors.
Also after replacing these capacitors you may need to install a
cooling fan on the heatsinks to prevent them from getting to hot.

Phillips flat screen tv left half of screen is black right side is dim and flickering


Is your tv less than a year old? You need to call Phillips and see if it is covered under warranty. If that is not the case you need to get a few estimates. You want to know if it will be cheaper to repair or replace your tv set.

My phillips hdtv turns on with blue light but no picture and wont turn off unless its unplugged remote and buttons dont work either


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

LCD screen totally white when turn on


The HP is a flat screen monitor used with many desktop computers. When the LCD on your HP monitor goes white, it is an indication that your monitor's inverter board has gone bad. The inverter board is a small circuit board that transfers power from the monitor's main circuit board to the LCD screen. Replacing the inverter board means dismantling the HP monitor.

1. Power down your computer and unplug the HP monitor cable from the back of your desktop. Disconnect the power cable from the back of the monitor. Relocate the monitor to a flat work surface. Place the monitor with the screen facing downward.

2. Remove the Phillips-head screws from the monitor's base stand and from the back cover. Lift the base stand off of the monitor and remove the back cover. Peel away the foil from inside the monitor around the internal circuit board.

3. Locate the inverter board near the bottom of the monitor's casing. Unplug the power cables from either side of the inverter. Loosen the Phillips-head screws from the inverter board. Lift the old inverter out of the monitor's casing and set it aside.

4. Place the new inverter inside the monitor. Replace the Phillips-head screws and fasten it in place. Reconnect the power cables to the connectors on each side of the new inverter. Replace the foil around the outside of the main circuit board.

5. Replace the back panel and base stand, and their retaining Phillips-head screws

I hope you find it very helpful.

Vertical bars on the screen


You will be needing a main board or some times the power supply is erratic causingm the mainm board to lock up. I have not had good luck finding parts for this brand,but salvage sites such as shopjimmy.com have helped. If you want to try to solve and have technical ability look for swelled capacitors inm power area first....iof all looks ok,then price the main board
