JVC LT-50A330 TV. Sound but no picture. Screen is blue

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.
Check the cables, connectors and connections.
Take it to a repair shop.

LG LED tv no picture but do have sounds,

the LCD screen has a light source (like a monitor). It can be an lamp (like a projector TV), a mercury tube (like a monitor) or a LED-based lamp (so-called LED TVs have that, not to be mistaken for OLED TVs, where each pixel is a LED). I don't believe this model is an OLED. It could be one of the others, most likely a mercury lamp that lays at one side of the monitor and illuminates the screen.
You could shile a flashlight to the screen (from close distance) while the TV is powered on and see if any image is being formed on the LCD. If it does, the lamp is burned out and needs replacing. If no ghostly image is seen, then it could be the video processor and then it's a bigger problem.

Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

Samsung 40" LED TV Display

Not familiar with this particular model of samsung LED TV, but ghosting and shadowing are usually an accepted manufacturer's defect.

If you're still under warranty or within 30 days of purchase, contact the company that sold you the TV or Samsung warranty department.

If you're out of warranty and you don't wish to deal with this, contact a TV repair shop. They will most likely tell you that it's not worth repairing and recommend you purchase a new TV.

michael spencer · Answer 2 · 4/2/2008 12:00:00 AM

This is caused by a failure of the main board. The failure causes the refresh rate of the unit to be off creating a trailing or ghost effect. This will require a technician to replace that board though. Hope this help.

Matthew Spark · Answer 3 · 11/28/2008 12:00:00 AM

your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.
