Hello my prodcan 55 inch tv will not go out of YPbPr/AV not even with the remote control

Proscan is produced by ON Corp. They are a leading producer for most LCD screens used by a large group of TV makers. Proscan used to be a high end RCA product. The CEO of On Corp was the head of the Proscan division of RCA. After Leaving RCA and Beginning On Corp he purchased the right to the Proscan trade mark. Thus a new beginning for a old name. Many people still belive it to be an RCA TV but it is not. It has good ratings in most reviews for TV's in it price range. It is now a sears brand much like Dynex is a Best But brand.

My proscan did this. I took off the back. Spotted the buldged capacitor. Went to Fry's to find a replacement. They didn't have one but they referred me to someone down the street. Called, he had it. Cost like 2 bucks. Got a soldering kit for 15 bucks. Removed and replaced. And it's like brand new again! 4 years later, the main board is going out :/ that's not so cheap.

hi i'd check the speakers first, test the ohms with a multimeter if ok you could have a bad amp ic on the main board, or a faulty capacitor,thanks shaun

Hi Elissa, Here is the link to the manual online for your television. http://www.manualslib.com/manual/484186/Proscan-42la30h.html

Internal video ccircuit or card is damaged. If you Proscan is on warranty, claim the to change or repair it. If warranty is over and you can't repair it yourself, send it to repair.

Lcd/Backlight! Main Problem On the led,lcd is the Bad lcd ribbon or Bord, Try turning off all the lights and Turning it on, then kneel down to the ground and see if u can see Channels changing when u click up/dwn or volume or even the Fuzzy look when theres no cable going to it. if u can see then its probably a bad board or chip.Hope This Helps :)

Usually a voltage in the power supply constantly changing instead of being stable causes this.
