I got a Sony TV that keeps going off after 45 minutes to an hour. When the TV goes off it doesn't flash the red indicator. I am assuming the indicator stops flashing after a certain amount of time. I know the flashes is 7 because I went through the error code menu. Remote: Display, 5, Vol -, then power. It labeled TEMP with a number 7 next to it. Does anyone have any ideas what this maybe? When it plays it looks perfectly and no imperfections, and no the TV is not dusty.

Disconnecting did fix the issue but the downside is that I can't use the remoteComment

Hello,
on this laptop acer aspire v571p the led of the power indicator blinks blue for periods of 1s lighted and 3s off after switch on and this indefinitely.
i tried the hard reset, cmos reset, changing the ram without results.
in order to reach the cmos battery i disassembled the laptop and did several mesures with my multimeter.
The 19v, 5v, 3v are well established after the chip 5v-3v. the following signals : 3d3v_aux_kbc (which supplies the sio chip) and 3d3_s5 are well established also.
but the signals: 3dv3_s0, pw_slp_s3# and pw_slp_s4 oscillate at the same... -
Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Hello,
I have a Samsung DM32D display.
When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.
Here’s what I have tried so far:- Disconnected the cable between the mainboard and the power supply → the backlight turns on.
- Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
- Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.
From these tests, I suspect the problem might be on the mainboard. Could anyone...08-24-2025, 03:47 AM -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50

👋🏻I recently got a tx-pr42gt30, I bought it in non-working condition. When I opened it, I saw that all the transistors and diodes had been removed from the tnpa5330, and several microcircuits were in poor condition, so I decided not to try to repair it. Instead, I bought another tnpa 5330 (also AB), which was already repaired (according to the seller, the board was repaired and worked before the screen was damaged), transistors were also changed on it, but Chinese copies were installed (there is no round hole in the middle, the inscription is easily erased) and a pair of transistors that...07-19-2025, 07:53 AM
