Hello all. 3 years back, with your help, I replaced the LEDs on this TV. It's been working great. Yesterday, I turned it on (garage TV), and it has blurred horiz / vert lines as you see in photos. Definitely no physical hit or damage. Top 1/6th of the screen is perfect. Could it be main / TCON board? No tabs to cut on this model. Thank you...

👋🏻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...

Hello everyone,

I have a problem with the RAM memory that is soldered onto the motherboard. Can someone please help me with how to disable the soldered RAM, possibly by removing or shifting resistors? The model in question is an Asus VivoBook D415U.

I’m attaching some pictures.

Thank you all and best regards!...

Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

i know that in linear power supply the noise will be very low comparing to SMPS supply....

Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

It does power up when pressing the power button.

I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

Could this be an PSU or eMMC issue ?
