My screen went out but i can still hear sound is my picture tube out ? its a 04 65" 1080 series

Most likely the power supply board needs to be replaced. It could also be the backlighting. A few TV's have a separate power board just for backlighting, but not many.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

take it in for repair and a quote to fix

Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

If the display isn't working and according to the conditions you described yes it is the picture tube. You could contact Samsung and get a replacement for it.

okay, 1080 Series isnt the model... the model number is on a sticker on the back, and that's what you need to find first. Just from the description, though, sounds like your focus block is bad; that will cause the problem you are describing... not cheap, but way cheaper than a new TV.

if theres power its more likely your picture tube went out or blowed & will have to be replaced or repair. If there is there sound other than the power like static or normal sound. then it's definely the picture tube but if theres nothing but juice & its a newer model tv its a problem with the fan or lamp

u need to reset the screen options back to regular spec if its not a 1080 p tv if its a regular tv you will need to use the 1080 p tv to fix it before you can use it on any tv

most likely the convergence Ics have failed. Check F9a04 and F9A05 pico fuses if they are blown you will need to replace them and the convergence Ics.They are located on the center board they are green and look like resistors without the color band. see the photo

check the capasitor near the plyback value 250 volts and also the B+ capasitor
