Question about Projection Televisions

1 Answer

I have a picture tube type television set I purchased brand new around November 2004 from a Sam's Club store - Sylvania 32" set, model #SST4324. I recently purchased a new house and set my TV up in my new living room. Everything seems typical for about three weeks - working fine, and normal as usual. One day I turn the set on and the screen is completely black except for a thin multiple colored line about 3/4 of the way up the screen that ran horizontal across the screen. Sound from the channel the set was on was clear, as if you were normally watching the set. You could also change the channels with the up or down buttons and could hear the different audio for those channels. However the screen did not change at all. Nothing but the thin colored line. Does this mean the picture tube blew? Is the TV worth fixing? Please let me know what you think. Thank you for your time and help.

What causes the yellowish hue in the centre of the screen


There are several different types of projection sets: some use 3 picture tubes, red,green,blue--if this kind of set is what you have the coolant used in the blue tube is bad-----this type of problem leaves red and green which = yellow.

Most common in Samsung, Philips, Magnavox type sets.


If it is a newer set without picture tubes (a dlp style set) yellow in the middle of the screen would denote a damaged optical light engine.

Let me know brand, model number, date made----all are on back of set.

What is the service call charge for replacing bulbs for a panasonic projection xf series tv ? the color is dim; the set is 10 years or so old


Your set uses 3 CRT's (Cathode Ray Tubes) to create the picture for your set. The cost for replacing all three of these tubes would be unreasonable for a set of this age. As a television technician for over 25 years I can tell you that the cost of parts, plus the labor would be in the range of $1,200 - $1,600, and that would be if the parts are still available.
But based upon the symptoms that you described in your post, there may be another issue with your set being dull. The CRT’s are cooled with a liquid that is pure, clear, ethylene glycol. This liquid can have an algae growing inside of the blue and the green CRT’s, I have seen this many times over the years, and all that needs to be done is to replace the fluid inside of the set. This can be a less expensive repair than the first, but, it can still be a bit steep because the liquid is not cheap.

I would suggest that you call around and see what it would cost for a local servicer to come to your house and diagnose the problem with the picture quality. You should be able to get a servicer to your house for between $50.00 - $75.00, and they should be able to provide you with a very accurate estimate for the cost of the total repair.

My next suggestion is to look into what a new set would cost in your area, (as a repairman this is not what I would normally suggest because repairmen do not get paid to tell you to purchase a new set, we only get paid to repair televisions).
You are the customer and you should be well informed about the cost of a new set especially since we are moving toward the digital only signals and the LCD sets are becoming more affordable. I am not sure where you live, but if you have a Best Buy, Costco, Sam’s Club, or Walmart close by have a look around and don’t forget to check out the internet for these stores before you visit them in person.

If you choose to replace your set, I have some suggestions for you to consider.
You currently own a Panasonic, this is one of the best televisions still on the market today, (My Opinion as a consumer and a technician).
Try to stick with the trusted name brands like Panasonic, Samsung, Sony, Toshiba and Pioneer. Please stay away from brands that you have never heard of or cannot pronounce,(such as ILO, Dynex, Vizio, (again, just my opinion) they are only trouble for the customer and for the repairman, (I have seen many customers that have had buyer’s remorse after I give them an estimate on a television that is just over a year old).

I hope this information allows you to resolve this issue.
If I have helped you, please help me, and rate this suggestion the highest FixYa rating. (Two Thumbs Up)

On a white picture my screen has a yellow color to it and at times mill have a blue blur on the bottom left corner of the screen. also i get blue dots in the middle on the screen.


Hello: Seems like you have a picture tube problem. The yellow color is from a weak green crt. I suggest replacing the Red and Green Crt's in this model. They are nortoriuos for Failure especially the Red. The cost for these tube vary from 110.00ea to 150.00each. I don't know if you want to spend that type of money on this set, as i Know this peticular set has an expectional picture quailty, my experience with replacing sony picture tubes, is to replace all three tubes, as the new ones will show brighter. So replacing the red and green crt's and not the blue is not recommened. But thats up to you, you might not notice the color difference yourself. You also have the option of sending the Crt's for refurbished ones or having the originals rebuilt by a company in Calif, called VDC, Video display Corp. They sell and refurbish sony CRTs. This route is much cheaper, the only problem is having the crt's taken out and sent for repair. The other option is to think about purchasing a new set. As this repair price could reach into hundreds of dollars, Around $600 to $700 for parts and Labor..

I have a Sylvania SRT2227S with video rollover a the top of the screen.


I am unfamilliar witht this model however it appears to sound like a Cathode ray tube Television , roll over is caused by a fault in the vertical frame output stage if it is an old Hybrid set it will probably be a vacum valve that controls this ( however havent seen this type in 20 years all transistor and intergrated circuit outputs now ) and repair should be undertaken by a qualified engineer . if an engineer is not available then someone with electrical knowledge and safety precaution training as the insides of these type of televisions generate lethal voltages at several points in the system . The coils around the tube base are the deflection controlers and they control the size and shape of the picture depending on the voltages and positioning of the screen mask's to shape and stabilize your picture . Any one touching these without the correct tools may damage the set further by distubing the convegence settings , in short I suggest that this is a job for a trained TV technician ...

Need new lcd screen for 32" sylvania


I am not aware of replacing just the front screen, that is the LCD display and is most likely more than the set cost. Please be very careful when purchasing something like this on e-bay. I can't see how they will have a display for such a new set. Can you give me a model number and I will do the homework for you?

I was not aware that there are HD specific antennas. But, that aside, I don't know enough to answer without the model number of your set and information about the antenna, such as how you have it connected, is it amplified?
Best Buy is usually pretty good about helping with solutions. Have you called or visited a store? Be sure to ask for the Geek Squad person/s that are specifically assigned to TV's. Also most of their Dept heads are pretty knowledgeable concerning conversion and the associated problems. My apologies for not having a better answer.

Philips Projection TV Bulbs need changing


Buy a new television. The "bulbs" are actually small picture tubes, also referred to as CRT's or guns. There are three of them, Red, Green and Blue. The cost for the tubes alone will probably exceed the original purchase price of the television. If the new tubes do not have the lens assembly attached, then you will need to transfer the old ones. This involves draining, cleaning, and refilling the coolant chambers. Once installed in the set, there is a series of mechanical and electrical adjustments required, to get the picture aligned or converged. This procedure is not recommended for the inexperienced. If cost and time are not an issue, then everything can probably be found on the Internet. Simply search the web for your model number. You will need the remainder of the model number first. There are at least eight models starting with 46PP9302. You are missing three additional characters.

JVC AV-56WP74


You would need the service manual in order to change the picture tube properly as there are dangerous voltages stored inside the tube also the tube would have to be set up properly as well. You can get the service manual for your model at the following link. They will email it too you right after purchase. Heres the link.

replacement of a picture tube in a itc222 chasis is one of my least favorote things to do here at the shop. average cost for a tube is around 250... replaceing the tube takes some time and the set has to be completely disasmbled. then reassemble and adjusted. i believe union electronics offer these tubes. you have to get the tube type of the tube itself there are several tube +lens combinations that have to be considered. willie at fordtv.com

RCA P52830BL picture is bowed and colors separated.


There is a convergence printed circuit board that likely has a few bad components. If you decide to get it repaired, the technican will probably check for fluid leaks from the picture tubes coolant area which has given problems on this model also. If the picture quality leaves a bit to be desired, it may be a wise move to upgrade to HDTV. A Sony KDS-55A20 model has a great picture and should be less than $2300. I just saw one at a local Sams Club store.
