Question about Philips Projection Televisions

Open Question

I have aphilips 37" TV model 37pf55200/10. It is two years old and it is jumping from 1 channel to another when watching the built in free view. It also shows green squares for a few seconds every now and then. I was watching free view last night , when at 11.15 i got "System software update in progress" this should last approx 45 mins. It is 11.44 the following day and it is STILL showing that message. I can't view any channel. It doesn't appear to be doing anything at all. Please advise. (I no longer have a receipt for the TV) but there is obviously a fault. Who do i contact ?. Is the update a common thing and how do i get my tv to work again. This was a lot of money and feel after two years i should NOT be having these problems as we went with a reputable company.

some of these tvs have internal adjustments for everything including alignment which fixes the double image problem. if you remove the cover you will find a lot of little adjustment dials. you may find that they have symbols that show what the adjustment is for. if you want more info. email me at sb1216us@yahoo.com

SOURCE: SONY KP-57WV600 - Small green lines across the screen

According to several sites, the problem is with the convergence via the voltage on the color ray gun tubes that get out of adjustment. They are also known as retrace lines

Sony wanted between $150-$300 to diagnose and fix -- instead I was able to complete this repair in less than 15 minutes!
Since I had been through the routine once more and I was sure others are running into this issue,
1. All you need to complete this guide is one flat-head screwdriver and one Phillips screwdriver as well as a delicate touch.
2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.

3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.

5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.

6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.

7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

SOURCE: TV will not turn on

Good Morning Chris,
OK, first of all lets unplug the TV and wait 15 minutes for the High Voltage to discharge.
Remove the back and follow the power cord to the power supply. Somewhere around there you should find a fuse. (there may be more than one) get a bright light to look inside and try to find as many fuses as you can. Remove each fuse one at a time and check them with an ohm meter.
If you don't get a good solid reading on any of them replace the fuse or fuses with the exact same rating. Even if you get a reading and the display is jumping around and will not stablize, replace the fuse. Usually a good fuse taken out of the circuit will display a good steady reading on the meter.
I hope this solves your problem.
Have a great day!

You need to clean the mirror inside the television and maybe even the optics of the light engine. The dust is building up and the light cannot reflect cleanly off of the mirror.

Those links all contain service manuals, your exact unit will be one of them...
I think, though, you will have to get a "Quote" for a repair.

These units are close enough to the warranty end period that I would suggest that you contact Sanyo and Sony requesting warranty service. Talk to a supervisor and be persistant. It may take a few calls.
Keep us posted.

My tv jumps from channel to channel and turns itself off you can be watching bbc1 and it goes off and comes back on to itv


It sounds like the circuit board that controls the channel/volume/power/etc. is shorted out. You'll probably have to contact the manufacturer and see if the set is still under warranty. If not, contact a local TV repair shop and tell them what the problem is and if they can give you a quote over the phone to fix it. You can then either get a second opinion from another repair shop, or weigh out the price of a new TV against the cost of repair. Hope this helps...

The short version: Will a 14-year-old TV work with digital-to-analog TV converter? Specifically, I have RCA Model G25342AT, built in Sept., 1994. In case yes, converter should work... Trying to connect...


The converter box should work. Getting the remote to work with the TV might be a challenge. You might have to stick with two remotes. It used to be in the old days you could plug your tv power into the remote that way you would turn the tv on with the tuner remote but I be they stop doing that.

There is website that will let you check the digital televison signals for your area. This site should help you:

Toshiba 51H83 51 in. Rear Projection pisture issue


I have a wild guess. I have the same tv and channel 72 is the proper channel to watch tv on. I don't know why, but maybe try channel 72 instead of the usual channel 3. Good luck, maybe a quick fix, maybe not!
