If you have on-screen display change to video input and try bypassing tv tuner using audio/video cables. If no osd, problem could be shorted picture tube or problem on crt board, often caused by leaking coolant from tube(s). This is fairly common on your model. Hope I've been helpful.

I have a Panasonic Quintrix F TV. About 6 weeks ago the tv screen started displaying

Rule out the signal source by seeing if same issue when a DVD etc is used.

Usually a wave like motion from bottom to top is either signal related or a problem in the power supply (wave moves from bottom to top suggests that).

If not on rear inputs (A/V) it is not the power supply.

Model number is not indicated here and might be helpful.

I have a Samsung Rear Projection TV HCL5515W. Getting a burning smell after the TV died wth a funny sound. (Red light still comes on). Any clues? One of the posts talks about a blown up capacitor. Any idea...

maybe theres other parts is opened causing to blow up the capacitor. the best is to have to repair your tv to the qualified technician coming from samsung service centers in your area. that problem is easy for them.

How do you adjust the focus lenses for an HCL5515w TV?

You have one of two problems. Sometimes both.

Problem #1) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc.

Problem #2)

Your TV may have a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can hire a pro. If you want to do the repair yourself check the site Their kits include a step by step picture instruction guide, original OEM parts, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Samsung HCL5515W...when using coax input pic convergence is off, red and blue seem off....when I use the component inputs it constantly flickers between the squigly lines and picture with convergence off?...

on component your device may have to be on progressive. old dvd players you could switch back and forth on progressive and normal. the squigly lines sound like you need to make sure its on progressive. hook it up using the yellow video slot on player and tv (any cable will work). go into menu and look for progressive and change it on.

My samsung HCL5515W turns on has audio but no pic

Your loss of video is likely caused by the failure of the high voltage power supply necessary for the projection CRTs in the set. The supply may be separate and user removable.
Check with Samsung and ask about a possible repair service or the replacement cost.
