Top 20 Sony KP-46WT500 46" Rear Projection HDTV-Ready Television Questions & Answers

I Get a similar problem with my Philips TV, which I believe is a relay playing up. I find pulling the power and leaving it ten minutes usually discharged the capacitor holding the relay open and when I plug it in again, all is well. Had the issue for 3 years, it always works for me

you might have burned to LED screen out GET A NEW TV

you will need to trouble shoot the amplifier section which have bad capacitor or the amplifier get bad. if you don't have enough knowledge in repairing in electronics as will as tools and device as my advice just send it in the trained trusted tv repairman.good luck

Pull the lamp out and with a flashlight look at back of the compartment. There should be a cutoff contact switch at the bottom where the lamp pushes it inward when connected. If you dont see this, it is possible you may have inadvertently pushed to hard when inserting the lamp and that switch has to be replaced. It is part of the projection engine/unit and unfortunately that will be expensive if that is the issue. Good Luck

yes their is a built in tuner.

2x2" tweeters and 2x5 1/2" as for watts and ohms I can look and see

Check the speakers with a meter (like checking a fuse--the ones in this set are fairly standard and will have ohms and wattage marked on them.Rather unlikely both would fail and if they test good you may want to see they did not get switched to OFF in main menu.There is a reset but try these suggestions first.

Try using the MENU button on your remote control to go into the TV picture settings menu. Change the mode to NATURAL, You can also try to manually adjust the color in the COLOR SETTINGS mode.If that doesn't work, check out the handy troubleshooting chart in TV color problems and see if another solution will work. I hope this helps!

The power indicator should blink a series of blinks pause slightly the keep repeating the blink sequence. let me know the blink sequence and I can let you know why the set is shutting down.

follow power cord (set unplugged) to power board and the glass fuse there--check it first.

Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

very common issue indicating the Green CRT has shorted and will need replacement. You can get the Replacement Green CRT for your model from www.tvrepairworld.com they are listed under the Projection Tube CRT catagory

Unless you have experience repairing power supplies, best to have a shop look at it. it could be dangerous.

Ur tv have a problems known as a convergence pictures problems,it is dead.Tv have any colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?Yes,than the tv have a dead convergence board to causes these problems.The tv convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost u like $300-350 for parts and labors.

Can you verify the model number and see if its A KP46WT500 model? If so chances are just the convergence Ics ( stk 392-560 ) and pico fuses are the problem. There are 6 3.5 amp pico fuses directly beneath the heat sink fins on the D board ( where the Convergence ICs are located) Check those six pico fuses and also two 5 amp picos on the G board ( where power cord plugs in) if any of the picos on either board are open then the Convergence ICs will require replacement.

Unfortunatly there is no magic reset to fix something like this. Most likely one of the power supply boards is bad and keeps shutting the unit down. You can however unplug the set for 30 min and try it then if it is something hanging the unit up this could clear it. You also need to make sure all your cooling fans are running and the bulb is good and intact. There are sevral issue that can cause these problems but without testing them I would just be having you buy parts till we figured it out and thats not the best way to approach this. If it were me I would have a service tech the set and give you an estimate and a cause for the problem. I would also get it in writing what he is going to fix and if the problem is not fixed after the first attempt, that the repair service garuntee their estimate and give you a warranty on the repair. the reason I state this is that there can be more than one issue and it can snowball and before you know it your spending more on a repair than to replace the set.

Check the 4.7 ohm resistors often one or two will blow when the Ics fail

Hello LIAM DOYLE,Welcome, and thank you for using FixYa!To answer your question: The symptoms you see are typical after a rough moving of the television, the television being hit, or knocked over.The Red Drive Jet will have to be replaced, to bring the colors back online properly. Then all three jets will have to be re-calibrated and tuned into focus.Hopefully you can find a local television repair center to do all of this work for you in an affordable manner. Most of the time though, the cost of the part and labor is very close to the cost of a replacement set.Have a great day!

very common problem the 2 convergence ICs and the pico fuses will need to be changed. The Sony type 1 convergence repair kit from www.tvrepairworld.com is the correct kit for your model and contains the two ICs and the 8 pico fuses plus the CD with repair instructions.
