Question about Samsung HCL4715W 47" Rear Projection Television

1 Answer

HCL4715W Red Tube needs replacement

Does anyone know where I can get a red tube for this model of TV? Sears won't replace it (they say no parts are available), so they're giving me credit for a new one, but I hate to get rid of it since it's performed flawlessly for 5 years. It only failed 2 weeks after I had them come out and clean it for the first time under the extended warranty (go figure!).

I have Zenith rear projection TV Model IQC60H95W.The blue tube does not work. The red and green project. Is this a bulb or tube and are they available to purchase? The TV was made in 2001


This is a CRT(cathode ray tube) not a bulb. A Bulb is totally different. If you replace one Tube, you need to replace all 3 or the colors will never match properly. However, This model no longer has parts available. Even if they were, the cost would be close to $1000 in parts. I would not recommend repairing this TV.

Can i fix my tv screen is red


Toshiba 36A10 36" TV is the model you have indicated---

If the screen is all red and or too bright (no green or blue can be seen) the problem is in one of two places: Either a shorted picture tube or the board that plugs onto the end of the tube.

That board sends red,green, and blue video and information to the picture tube via 3 pins on the tube (the K or cathode for each).

The set will have either 3 IC's on that board or 3 transistors, or a single larger IC for this.

to troubleshoot this:

I would locate the Red Cathode and unsolder that pin at the socket on that board--takes red out---if you have green and blue picture then---it is either the IC/transistor that feeds that on the board or the tube itself.

If it has 3 chips (usually will each have a metal plate attached for cooling) you can either remove and replace the red one OR what I do is swap it with the green or blue chip---if suddenly you now have a blue or green only screen you know that part is bad--simple as that.

If for any reason the picture tube turns out to be bad--you are finished and so is the set= way too expensive to replace it.

Let me know if you have questions or need advice.

The screen has a yellowish color tinting the entire surface. No blurring, just poor color. I'm thinking the 3 tubes(red, green, blue) may be toast?

Blue CRT issues?


Yes the puddle is related to the Blue CRT coolant leaking. You are most likely going to need a new Blue CRT drive circuit board and quite possibly a new Blue CRT if the CRT got too hot from not haveing a sufficent supply of coolant. You can get replacement CRT drives and CRts at the following link.

All screen is red


IF THE SCREEN IS ALL RED WITH VIDEO VISIBLE AND RETRACE LINES. ADJUST SCREEN CONTROL IN THE FRONT FOR THE RED TUBE ONLY. TURN CONTROL COUNTER CLOCKWISE. IF THAT DOESNT DO IT THE TUBE CAN BE REJUVINATED.

Red stand by light blinking


5 blinks = lamp driver (ballast) failure.

1-468-798-14 for the 610 model

replacement is done from the back of the set, should be straight forward, keep the red ballast wires apart for best results

if a tech replaced the red tube, you have an older tv where 5 blinks is the AKB error meaning your CRTs are getting old.

Need new green picture tube


You dont need a new tube. What you need is to repair the seal on your old tube and replace the CRT coolant fluid. There is a coolant chamber attached to the tube with long bolts with springs on them that contains coolant to prevent your tubes from getting hot. Yours may just need tightening, but I would replace the seal just to be safe as thecoolant can and will destroy your circuit board if its allowed to continue to leak on it.

Samsung HCL4715W will not power on


At five years old, I doubt it will be worth replacing the power supply , a picture tube or two and possible the signal board. Cut your loses and get a new set.

Toshiba 32A41 TV -- color problem


Toshibas are notorious for developing shorts in the inernal guns of the picture tube. In your case the green gun is shorted to G1. The noise you heard was an internal arc between the elements. It is unfortunate however, the repair of this problem usually requires the picture tube to be replaced. Sometimes a savvy technician with sencore picture tube rejuvenator can remove the short. This however usually does not last. Scrivitron
