No image, Just red and blue vertical line on display.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

Screen problem

I have the same problem. rca 26lb30rqd. The red light is on (steady), and when I hit the power button, the blue light comes on for a second, then goes black, w/ no display. Before this happened, the display was extremely bright with ghosting. The picture was un-viewable. Did you every figure out the problem?

Sound and manufacturers logo show on tv screen when powered up however no picture.

The inverter may have gone out. If the display is momentary such as for the logo, the inverter cannot hold the high voltage to sustain for the back-light. Shine a flash light on the screen and see if you can detect any images. If you can, then the back-light inverter is bad.

My pltv 26 plugs in i have turned the switch near the power plug on the standby light comes on but when i push power it turns green for a second or two then shuts off

Sounds like a built in protector kicking in. Something probably has shorted. Try disconnecting the inverter (should look like this: to see if you can get the TV to power on without a picture. Be careful - this is a high voltage board.

PLTV 26 LCD TV sound-no picture

I would suggest to check the 24 volts from the power supply to the backlight inverter board. If the voltgage is missing or lower then 20 volts, the power supply is defective. If the voltage is correct, you might have a defective light inside the TV behind the screen since you've replaced the backlight inverter board; you now the failure is not there. The lights are connected to the backlight inverter board.
Let me know if you need further assistance.
