This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.

Re: VIZIO E550i-B2 Sound - No Video Problem

Fixed an E550i-B2 today with fractured Power Supply CN202 solder joints.

This failure may be due to a 3-4X difference in CTE (coefficient of thermal expansion) between the glass reinforced plastic chassis and PCBs clamped to it by 13 screws, resulting in high forces directly applied to CN202.

To remove the force on CN202 I decided to 'float' the LED Driver PCB as follows:
- Remove LED Driver PCB
- Under LED Driver PCB, trim off the plastic locating pin near upper left corner and both right edge...

Re: Another SAMSUNG 2493HM !

Another 2493HM saved by this thread...

- Only 5.3V standby voltage present
- Both FQPF9N50C FETs shorted and RM801 open
- One FQPF9N50C drive transformer secondary open due to glue dissolving wire in a bobbin groove above the mounting pin.

- Scraped glue off everything!
- Replaced RM801, both FQPF9N50C FETs, diodes and zeners in the FQPF9N50C circuit.
- Repaired the transformer by digging glue out of bobbin groove to expose a mm of wire, and adding a piece of 30 AWG wire wrap wire to extend it...

Re: Samsung 2433BW: 2 seconds til black

Adding a 2443BW variant, "2 sec to black with input signal present"

- Monitor would toggle between dim Analog & Digital no signal present icons all day, yet go dark 2 sec after a signal was applied to analog or digital inputs.
- Determined the top lamp output would not fully light a spare lamp with either top or bottom internal lamps connected. Under this test the Analog & Digital icons were visible at the same dim level so both internal lamps appeared to be working.
- Removed the transformer,...
