My search came up with a DLP manufactured by LG/Zenith. If you have the user's manual check the troubleshooting section to check for a lamp failure if the TV is not turning ON.
Let me know if you require further assistance.

What fault would cause this TV to not display?


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

9 year old Sony Trinitron TV 27 inch; a red light is flashing "standby, timer"; have tried to cancel this but the TV won't turn on, just hear a clicking sound when pushing the power button


The key here is the number of blinks. The standby light should blink a count followed by a few second pause with the count repeating. That count coupled with the model number will giveme enough information to provide you with a solution. Can you uipdate this with that info please?

Thanks,
Dan

Samsung HC-P4752W Does Not Turn ON


The proble you have is an intermittant power supply or sweep power supply. Unless you can find a bad connection on the power and deflection board, this could be a very difficult problem to find. I have ran across this problem a couple of times, and after spending countless hours troubleshooting, I replaced the main board and all the problems were taken care of. The board part number is at samsungparts.com and I found the board for you. it is located here: http://www.samsungparts.com/part_detail.asp?catalog%5Fname=Parts+and+Accessories&product%5Fid=BP94%2D01266A&search%5Fmodel=HCP4752W Good Luck

Pioneer 65" TV Model # SD-643HD5 won't power up.


I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?

Tv won't turn on....


There could be few reasons that tv does not power On.
Power supply board got fried, deflection section got bad if its rear projection tv and if its dlp tv, lamp could be dead etc.
Model number and brand of your tv will show us what kind of tv is that to provide you some helpful info about problem.

Projection TV Phillps 60PP9202/17F, bought 2004. Was watching and suddenly the picture went out. All connections are good and components work. Can you help?


Hi.

If there is no power at all, then it is either the power cord or power board inside the TV.

If after the fault the TV went in standby and does not wake up, then the TV is in protect mode.

In protect mode higher voltages from PSU gets shut down and TV remains in standby.(see also Why my TV does not start up and remains in...)

Try first leaving the TV power cord unplugged for some times, let say one hour or so. Then connect powr

If that does not work, and you keep having the TV in protect mode, it means that there is a fault.

In that case call the support number listed on Philips user manual to arrange repair.

If you are a technician I can try locating parts, service manual and giving more directions. Common faults that affect a Philips rear projections are convergence, PSU board, lamp and ballast assembly.

Regards.

I have a somsong hd tv and when i push the power button the tv want come on no picture. I hear a click sound every twenty seconds but no power seem to be getting to the picture tube tv mod# LNS4041DX


Based on your message, your TV has a bad high voltage section. Probably the HOT (Horizontal Output Transistor) failed or shorted and it either killed the high voltage or there's a current fluctuation; that is why the picture went, but there's a clicking sound. Then, when you turned it off or unplugged it the protection circuit remained active.

Once the high voltage fluctuates, that's the time the TV would create a clicking sound.

There's a 75% probability it will require a high voltage and horizontal deflection amplifier overhaul. The normal cost of that should be less than $200 if you take it in.

For this problem, I would suggest to contact a repair tech and have him take care of the problem.

Good luck!
