Re: model 32v434tyx6 RCA TV
SEEMS THAT YOUR POWER SUPPLY IS ON SHORT AND IT'S SELF PROTECTING YOU WILL HAVE TO HAVE A PROFESSIONAL TECH TO DO THE JOB I JUST FIXED ONE WITH THOSE SYMPTOMS AND I REPLACED THE COIL PLUS A COUPLE OF RESISTORS AND IT'S ALIVE AGAIN
THE DOWN SIDE IS THAT THERE IS NOTHING YOU CAN DO IF YOU DO NOT KNOW WHAT TO DO, IT'S NOT AN EASY TASK
I had same problem and thought it was the flyback and the horizontal transistor,
so i replaced them as to the internet stating thatwas the most common.
tried it - same old thing, nothing. tested a resistor i beleive. its number is r801 i beleive.
it has four color bands - red, ?black,green, and yellow.
going to the tv fella for the part tomorrow.
will try and see.
if anyone has anything else on this - please post.

A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.
Trying installing a new power supply. This is the main problem with tv's with the issue. But if you just bought it I would try to get my money back from where I bought it from. Installing a power supply for a tv is not that hard at all.
We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.
i dont have a soultion for you but can tell of my experince with rca 52"dlp after having mine for six months did same thing sent it to the repair shop it stayed there for three months then they said they couldnt fix it tried to talk to rca cust serv reps who basicly said they didnt care after two more months i finaly got the store manager where i bought it to go to bat for me and they agreed to replace it but with a lower grade model and no warrenty as they said mine had expired even though it had been broken for eight months after three months the new one did the same thing i was told it was the light engine which cost 2 grand and were on forever backorder and id just get another tv before putting that much in that tv but it wont be another rca hope this helps now i have a 100lbs paper weight firstname.lastname@example.org
