For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

Hi,
4 times blink shows Temp Error and requires temperature sensor replacement in Sony KF-50WE610 TV

Hi Lucian

This is a common Mainboard failure problem on Projectors.

The unfortunate thing is that this can only be solved by having the part repaired or replaced.

Sound but no picture, tv will not turn off. Light goes red but a dim overall blue screen remains and fan is still running.

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )

if the lines on your screen looks anything like the image below, you do have a problem with the lcd, problem is you need to replace what is called the light engin. unfortunatly the price of this part is just about as much as a new replacement tv. Get a sceond opinion fron a sony service center near you, as i cannot see your picute. good luck

4 blinks = No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505.
