Pioneer pro99 standby problem

    Same Story - out of the blue. The set will not turn on. It attempts to, and the red light briefly goes to green, but then back to red, and no start up.

    I have the same problem,after I try to turn in on about 15 to 20 times it will come on. It seems that it comes on after it warms up. If iI accidently turn if off it comes back on right away. For now I have been leaving it on and just turning off the dish reciver , but I am afraid that the bulbs will burn out a lot faster if I do not turn it off when not watching it.

SOURCE: Pioneer SD-P6091K problem with turning it on

Is this set several years old, and has it been good till now? There is one on the internet, 8 years old for sale with the same symptoms as your friends. There is an internet site `tv-forums.com. Presumably you have already looked with the back off. Make sure there is not a build up of dust, which will cause overheating. If it has a 150 watt UHP lamp, or similar,(expensive!) it may need replacing. The lamp must be cooled by a fan, so make sure this is srill working. There should be a thermal cutout which automatically resets.

When the set goes into protection BANG like that, without any intermittencies, usually the convergence ICs have gone out and need replacing. I recommend using the STK 392-180s, which are the stronger upgrade to the 392-110s used originally. You'll need 2.

SOURCE: Pioneer SD-532HD5 Projection Screen TV won't turn back on.

the problem with pioneer projection tvs is that when they made the boards they never used enough solder for the circuits and you get cracks in the runs. thats why heat and cold will effect it. I had the same problem and I took out the board and resoldered every track I could and it works good now but my remote wont work if anyone has any info or prints to this tv please post on here

I have a pioneer Pro 200 and have had it for a dozen years. I have an HD in my office and the picture is so good and bright on the Pioneer I just cannot bring myself to get rid of it. The TV blinks off...


Im going to guess that if you try turning it on, sometimes you hear a "click" and nothing then the problem persists over and over until it finally turns on? If so, it's a problem with the power that "jumpstarts" the screen. Worn out capacitors on older models don't hold the necessary charge it takes to "start" the inverter that powers the screen. Once those start to go, it's usually bye bye for the tv. That is IF this is your problem. Let me know. Sometimes it makes hissing or cracking noises along with it. hope this helps!

Problem with Sony Grand Wega TV


This could be due to bad capacitors in the sweep supply, a bad High Voltage block, a bad regulator.

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!

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.

Sony Big Screen TV Not Powering On


This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,

The power supply or sweep power supply blew up, or the Horizontal/high voltage circuit went bad. If you have no tV repair experience, call in a pro to assist you in this repair. Good Luck
